plates, two colored. 7% Thymallus vexillifer, Ag., three plates, two 
colored. This work is to the fishes of Europe what Audubon is to 
the birds of America, a perfect iconography. 
We are happy to state that two copies of it are on sale in the 
hands of M..Augustus Mayor, of New York, who has been before 
mentioned as the friend and correspondent of M. Agassiz,* and we 
hope that they will be speedily placed in the libraries of some of our 
societies, where they will be accessible to the student of this much 
neglected but most interesting branch of natural history. There are 
three prices for the first division, viz. on ordinary paper, 75 francs ; 
on superfine paper, with selected plates, retouched with great care, 
100 francs; on Bristol board, (carton vélin,) the most sumptuous im- 
pressions, 150 francs. This work is published at the expense of the 
author, and we hope that the public will, in this case, do what the 
British Association did for the Poissons Fossiles, indemnify him for 
the cost 
17. Elements of Chemistry, containing the elements of the sci- 
ence, both experimental and theoretical, intended as a text-book for 
academies, high schools and colleges ; by Alonzo Gray, A. M., teach- 
er of Chemistry and Natural History in the Teachers’ Seminary, An- 
dover, Mass. 1840—12mo. pp. 359. 
A Manual of Chemistry, on the basis of Dr. Turner’s Elements 
of Chemistry; containing in a condensed form all the most important 
facts and principles of the science,—designed as a text book in col- 
leges and other seminaries of learning; by John Johnston, A. M., 
Professor of Natural Science in Wesleyan University, Middletown. 
1840—12mo. pp. 453. 
th the above compilations made their appearance about the same 
fime, and are both published with the same object—that of bringing 
the subject into a moderate compass, and within the means of all stu- 
dents. Unhappily for our reputation as advancers of science, almost 
all the works on chemistry which have yet been issued here, have been 
written on the basis of some foreign treatise. We hope the day is 
not far distant when American chemists will take a high rank as ori- 
ginal investigators.
