[Sidenote: L. S.]

Be it remembered, that on the twenty-second day of October, A.D. 1825, and in the fiftieth year of the Independence of the United States of America, RUFUS PORTER, of the said District, has deposited in this Office the title of a book, the right whereof he claims as proprietor, in the words following, to wit:--

"_A Select Collection of valuable and curious Arts and interesting Experiments, which are well explained and warranted genuine, and may be performed easily, safely, and at little expense._"

In conformity to the act of the Congress of the United States, entitled, "An act for the encouragement of learning, by securing the copies of Maps, Charts and Books, to the Authors and Proprietors of such copies, during the time therein mentioned;" and also to an act, entitled, "An act supplementary to an act, entitled, an act for the encouragement of learning, by securing the copies of Maps, Charts and Books to the Authors and Proprietors of such copies, during the times therein mentioned, and extending the benefits thereof to the arts of designing, engraving and etching historical and other prints."

It is not so much the object of the author, with regard to the various arts treated of in the following pages, to convey to professed artists, a more accurate and extensive knowledge of those arts, as to explain some of the first lines and principles of them, for the advantage of those, who may be induced to practice them occasionally, either for profit or amusement. The chemical experiments are such as are calculated to combine recreation, with improvement in useful knowledge--a knowledge of some of the leading principles of chemistry.--The true chemical terms, according to the new nomenclature (which, perhaps, may not be so readily understood, by some, as the more common and familiar names, but will be found sufficiently explained in the appendix) have, in this work, been applied to the various articles occasionally mentioned. Very few substances have been mentioned, which are generally considered poisonous, or otherwise dangerous; but it may be proper, however, for those who may attempt any of the chemical experiments, to proceed with caution, and carefully avoid the fumes produced by chemical action, especially in metallic solutions in nitric acid, and sublimation of mercury. Several articles in this little collection, will probably be found to contain some improvements, and if it prove as interesting to others, as a similar work would formerly have been to the author, his object will have been attained.
