Principio coelum, ac terras, camposque liquentes, Lucentemque globum lunae, titaniaque astra, Spiritus intus alit, totamque infusa per artus Mens agitat molem, et magno se corpore miscet.--VIRG. AEn. vi.
Earth, on whose lap a thousand nations tread, And Ocean, brooding his prolific bed, Night's changeful orb, blue pole, and silvery zones, Where other worlds encircle other suns, One Mind inhabits, one diffusive Soul Wields the large limbs, and mingles with the whole.

Table of contents (by pages)
- 1: Zoonomia, Vol. I by Erasmus Darwin
- 2: How sphere on sphere Earth's hidden strata bend
- 3: Not considering that to think is to theorize
- 4: Those belonging to gravitation
- 5: Probably consist of moving fibrils
- 6: After the lacteals have drank up the chyle from them
- 7: And is intermixed with the slender fibres
- 8: When fibrous contractions succeed sensorial motions
- 9: Spectra of black objects become luminous
- 10: Or a new configuration immediately takes place
- 11: That as the retina is nearly transparent
- 12: Now if these spectra were impressions on a passive organ
- 13: As our perceptions had formerly produced
- 14: Are associated together like our muscular motions
- 15: And conversely the convulsions shall supervene
- 16: Which were every day succeeded by delirium
- 17: When fibrous contractions succeed sensorial motions
- 18: Of the four faculties or motions of the sensorium
- 19: That exertion or change of the sensorium
- 20: That exertion or change of the sensorium
- 21: In like manner the sensual motions
- 22: When the focus is formed before or behind the retina
- 23: And the quantity of sensorial power
- 24: Are nevertheless occasionally causeable by volition
- 25: That are most frequently connected with volition
- 26: Many voluntary muscular motions become associated
- 27: That are sometimes indissoluble but with life
- 28: And the hollow muscles are excited into action by distention
- 29: Which are the motions of the extremities of the sensorium
- 30: For when we exert our volition strongly
- 31: To distinguish it from volition
- 32: These muscles act from the irritation of distention
- 33: Prevent unnecessary expenditure of sensorial power
- 34: That the paralytic limbs moved also
- 35: If the sensorial power continues to act
- 36: And the diastole in health be twelve lines in circumference
- 37: And the sensorial exertion be increased
- 38: Its quantity of sensorial power
- 39: Which is another sensorial faculty
- 40: And with their whole sensorial power
- 41: And the quantity of sensorial power
- 42: That the two other sensorial faculties
- 43: And a consequent torpor or quiescence succeeds
- 44: Because now the sensorial power
- 45: On Catenation of Animal Motions
- 46: Producing an increased exertion of sensorial power
- 47: In respect to the spectra in the eye
- 48: Producing a decreased exertion of sensorial power
- 49: And the consequent defect of sensorial power
- 50: The greater distention of the heart and arteries
- 51: This accumulation of sensorial power increases
- 52: If venesection and a cathartic have been previously used
- 53: A proportional debility is the consequence
- 54: A tree is a congeries of many living buds
- 55: And of the pistils of some flowers to the anthers
- 56: And in consequence a sensorium or union of their nerves
- 57: So true is the observation of the famous Malbranch
- 58: It acts wherever there is the medulla above mentioned
- 59: That an ivory globe may revolve on its axis
- 60: And by the particles of sapid and odorous bodies
- 61: The stimuli of surrounding objects
- 62: And therefore with the choroide coat of the eye
- 63: It appears that zinc was always found minus
- 64: And from those combinations of animal fluids
- 65: The refluent blood again distends or elongates them
- 66: The males have also pectoral glands
- 67: The great excess of pressure or distention
- 68: But it is the very rhinoceros that I saw
- 69: Invention is an operation of the sensorium
- 70: These catenations of ideas and muscular motions
- 71: Makes a part of this catenation
- 72: The sensations of cold and warmth
- 73: Puppies before the membranes are broken
- 74: It does not slightly compress the nipple between its lips
- 75: Nonne canis nidum veneris nasutus odore Quaerit
- 76: Is possessed of amazing ingenuity
- 77: Than of the odour and flavour or warmth
- 78: From this our aptitude to imitation
- 79: And from which there is a duct
- 80: And the lacrymal sack empties itself into the nostrils
- 81: And sternly surveys his adversary
- 82: Whenever they hear his cuckooing
- 83: But this proportion must always fluctuate
- 84: Assert that rooks can smell gun powder
- 85: And then repeatedly wash their faces with it
- 86: Was witness to a cat's suckling a young hare
- 87: He saw a great number of pelicans
- 88: And even under water in this torpid state
- 89: Pennant observes that the hoopoe
- 90: The same species of birds migrate from some countries
- 91: The rooks removed to the church
- 92: So that the materials of the nest
- 93: Of the cuckoo sometimes making a nest
- 94: To encompass a shoal of haddocks and cod
- 95: Like the operculum of some sea shells
- 96: There is one species of ichneumon fly
- 97: And in a few days the large caterpillars died
- 98: Or lie torpid the greatest part of the time
- 99: Or the centipes from devouring them
- 100: Then new catenations take place
- 101: All these catenations of animal motions
- 102: They are catenated tribes of ideas
- 103: Which confirms the other catenations
- 104: A very remarkable thing attends this breach of catenation
- 105: This association being dissevered
- 106: Or by gently vellicating the soles of their feet
- 107: And become dissevered by some violent stimulus
- 108: Or those catenated with pleasurable sensation
- 109: We either gradually awake by the exertion of volition
- 110: But even in our waking reveries
- 111: And are hence perpetually falling into new catenations
- 112: Hence an interesting play produces reverie
- 113: Which are generally subservient to volition
- 114: The irritation from external stimuli
- 115: Or in what is termed the convulsive asthma
- 116: As the expectorated mucus in coughs
- 117: All external stimuli are excluded
- 118: Which diminishes the general quantity of sensorial power
- 119: A tumour is protruded in consequence
- 120: No suspension of volition in reverie
- 121: And the reverie began suddenly
- 122: But the few stimuli of the tuberose
- 123: Which in reverie is not affected
- 124: Why drunken people are vertiginous
- 125: And he frequently becomes sick and vertiginous
- 126: The circumjacent objects become quite indistinct
- 127: Additional Observations on VERTIGO
- 128: After revolving till we become vertiginous
- 129: Which many vertiginous people experience
- 130: As are occasioned by faint ocular spectra
- 131: The irritative ideas of objects
- 132: Are accompanied with vomitings and vertigo
- 133: And of the associate motions catenated with them
- 134: Which were usually catenated with them
- 135: After great fatigue or inanition
- 136: So much sensorial power is expended
- 137: As soon as he begins to be vertiginous
- 138: Or of daily taking much vinous spirit without inebriety
- 139: Accumulation of sensorial power in hemiplagia
- 140: Because the sensorial power of association
- 141: When we possess an accumulation of sensorial power
- 142: Or configurations of the organs of sense
- 143: So as to produce pain and hydrophobia
- 144: Heat given out from glandular secretions
- 145: Till by the stimulus of distention they contract themselves
- 146: Which are called conglobate glands
- 147: And of the lacteals and lymphatics
- 148: And the salival glands are excited into action
- 149: That open their mouths into the ducts of the salival glands
- 150: Stimulates the excretory duct of the lacrymal gland
- 151: Further account of the inversion of lacteals
- 152: By stimulating the excretory ducts of the liver and pancreas
- 153: And regurgitate their contents
- 154: And the bile and pancreatic juice
- 155: The urinary absorbents act weakly
- 156: Like other diseases from torpor
- 157: Together with much viscid mucus
- 158: Are in truth unorganized materials
- 159: Haemorrhage from venous paralysis
- 160: Otherwise it is cured by venesection
- 161: Hence haemorrhages from the kidneys
- 162: And from the many vibices and petechiae
- 163: That sometimes the mouth of the lymphatic
- 164: BEDDOES very ingeniously concludes
- 165: And a part of the bronchial mucus
- 166: Which are called conglobate glands
- 167: As in the diabetes and scrophula
- 168: With the lacrymal sack and nasal duct
- 169: Kratzenstein put ligatures on the ureters of a dog
- 170: Whenever the lacteals are much stimulated
- 171: Which may be termed the aqueous diabetes
- 172: Hence this mucilaginous diabetes is a cure
- 173: The mucilaginous diabetes will require the same treatment
- 174: And cantharides in large quantities
- 175: The cause of diabetes might be more certainly understood
- 176: If the lymphatics cease to absorb that mucilaginous fluid
- 177: Pour them into the lacteal branches
- 178: He took a large spoonful of the decoction of foxglove
- 179: And died universally dropsical
- 180: When the original disease is a general anasarca
- 181: That the sudor anglicanus which appeared in England
- 182: The material still arrested in the mesenteric
- 183: Seem to be taken up by the cutaneous branch of lymphatics
- 184: When chyle is observed in stools
- 185: I then passed a ligature round several branches of lacteals
- 186: And refuse to obey even these stronger stimuli
- 187: And is brought into retrograde action
- 188: That the motions of the secretory vessels
- 189: And into solution of mild alcali
- 190: The inflammations of this viscus
- 191: Or paralysis of the secretory vessels of the kidneys
- 192: The Temperament of decreased Irritability
- 193: There is not properly a temperament
- 194: Such as delirium or inflammation
- 195: Owing to deficiency of sensorial power
- 196: Which may be called Synocha irritativa
- 197: Than that an additional stimulus
- 198: And the deficiency of sensorial power
- 199: Owing to the accumulation of sensorial power
- 200: Why people of these inirritable constitutions
- 201: Which induces the second fit of quiescence
- 202: The muscular system by the distention
- 203: And thus tends to induce quiescence
- 204: Return at regular solar periods
- 205: The quiescence may commence at any hour
- 206: The same quiescence of other fibrous motions accompany it
- 207: The quiescence of all the muscles
- 208: Depend much on the quantity secreted by the kidnies
- 209: After great exhaustion of sensorial power
- 210: And liable to inflammation after a temporary quiescence
- 211: Flatulency and hypochondriacism affect the intestines
- 212: And the febris sensitiva pulsu debili
- 213: May be considered as the febris irritativa pulsu forti
- 214: Which produce or elongate the vessels
- 215: There is a great absorption of variolous matter
- 216: Like the variolous matter above mentioned
- 217: Which cure the itch and lues venerea
- 218: 's pustules continue advancing
- 219: That the variolous matter is diffused through the blood
- 220: They were afterwards inoculated with variolous matter
- 221: That the variolous infection can be received but once
- 222: Which acts upon the mucus lining of the stomach
- 223: It is termed typhus sensitivus
- 224: Owing to the exhaustion of sensorial power
- 225: Why no external objects are perceived in syncope
- 226: He immediately exerts this act of volition
- 227: The fauces become more sensible
- 228: As well as by the excess of their appropriated stimuli
- 229: For this purpose of alleviating unavoidable pain
- 230: As the various kinds of epilepsy
- 231: The cataleptic lady had pain in her upper teeth
- 232: Similar to this is the syncope
- 233: And by other causes of quiescence
- 234: Many of the paralytic patients
- 235: Which are employed solely in voluntary exertions
- 236: The dropsy ceased for several weeks
- 237: Who towards the end of violent peripneumony
- 238: By expending a large quantity of sensorial power
- 239: Digestion strengthened after an emetic
- 240: A temporary coryza or catarrh is produced
- 241: When an emetic medicine is administered
- 242: And the secondary part increased sensation
- 243: Of a decaying tooth in hemicrania
- 244: Or inflammation of the membrane of the nostrils
- 245: Natural actions catenated with lunar periods
- 246: Which are frequently catenated with our daily habits of life
- 247: In this respect resembling the female catamenia
- 248: The laudanum was continued a fortnight
- 249: The periods of the haemorrhoids
- 250: Lacteals absorb by animal selection or appetency
- 251: These lacteal vessels have mouths
- 252: Selected from the aliment we take
- 253: Even though the stimulus be continued
- 254: The placenta is a pulmonary organ like the gills of fish
- 255: That the placenta was a respiratory organ
- 256: And the numerous placentas in consequence
- 257: And this ice was the liquor amnii frozen
- 258: Afterwards it swallows the liquor amnii
- 259: Hence new parts are acquired by addition not by distention
- 260: Since a part of the embryon animal is
- 261: The liquor amnii is secreted into the uterus
- 262: Be all of them rudiments of homunculi
- 263: Which are their viviparous offspring
- 264: Being supplied with nutriment by the mother
- 265: As the embryon increases in the womb
- 266: Who have attended to microscopic animalcula
- 267: And consequent secretion of the semen
- 268: Without the seminal or amatorial propagation
- 269: Which consist of a duplicature of the limbs
- 270: For about what can the fetus deliberate
- 271: Which are monsters thus produced and propagated
- 272: In others tushes instead of horns
- 273: And with gills instead of lungs
- 274: Which are termed vermes by Linnaeus
- 275: The breasts and teats of all male quadrupeds
- 276: That that action of the retina
- 277: The liquor amnii prepared for the fetus in the uterus
- 278: When the embryon has produced a placenta
- 279: Or that of deficiency of original nutriment
- 280: If the snail or worm could have impregnated itself
- 281: Hence those hermaphrodite insects
- 282: By the apposition of a duplicature of limbs
- 283: Into the membrane of the uterus
- 284: And in the unimpregnated seed vessels of vegetables
- 285: The new fetus exactly similar to the father
- 286: And besides the chemical attractions of affinities
- 287: And the matter of the apple the inert cause
- 288: Which compose the mouth of that lacteal vessel
- 289: Spectra from defect of sensibility
- 290: Activity of the Retina in Vision
- 291: Of spectra from defect of sensibility
- 292: Of spectra from excess of sensibility
- 293: So that those parts of the retina
- 294: After having been long exposed to little or no stimulus
- 295: The spectra described in this section
- 296: These reverse spectra are similar to a colour
- 297: Like oscitation or pandiculation
- 298: Of a combination of direct and inverse spectra
- 299: The internal spectrum was yellow
- 300: Or by looking through an opake tube
- 301: The reverse spectrum of any colour became faint
- 302: They change it into the reverse spectrum
- 303: And also the reverse spectra of both
- 304: Whose spectra are thus reciprocally similar to each colour
- 305: But that of the spectrum continues the same
- 306: Communicate with vena portarum
- 307: Bathing in pulmonary haemorrhage
- 308: Exertion of sensorial power defined
- 309: Jaundice from paralysis of the liver
- 310: From greater contraction of fibres
- 311: Motions distinguished from fibrous motions
- 312: Possess sensation and volition
