Review of Cleaveland’s Mineralogy. SF 
of pyrites, gave assurance of the existence of the precious 
metals in those substances ; or that the cutting of glass by the 
garnet, and by quartz, proved that these minerals were the 
diamond ; but if they were not precious metals, and if they 
were not diamonds, we in vain inquired of our companions, 
and even of our teachers, what they were. 
We do not forget that Dr. Adam Seybert, in Philadelphia ; 
Dr. Samuel L. Mitchell, in New-York ; and Dr. Benjamin 
Waterhouse, in Harvard University, began at an earlier pe- 
ried to enlighten the public taste on this subject ; they began 
to form collections ; Harvard received a select cabinet from 
France and England; and Mr. Smith, of Philadelphia (al- 
though, returning from Europe fraught with scientific acqui- 
‘sitions, he perished tragically near his native shores,) left his 
collection to enrich the Museum of the American Philosophi- 
cal Society. 
- Still, however, although individuals were enlightened, no 
Serious impression was produced on the public mind; a few 
lights were indeed held out, but they were lights twinkling in 
-an almost impervious gloom. 
The return of the late Benjamin D. Perkins, and of the late 
Dr. A. Bruce, from Europe in 1802 and 3, with their beauti- 
ful collections, then the most complete that this country had 
ever seen; the return of Colonel Gibbs, in 1805, with his 
extensive and magnificent cabinet ; his consequent excursions 
and researches into our mineralogy ; the commencement a- 
bout this time, of courses of lectures on mineralogy, in several 
of our colleges, and of collections by them and by many indi- 
viduals ; the return of Mr. Maclure, in 1807 ; his Herculean 
labour in surveying the United States geologically, by per- 
sonal examination ; and the institution of the American Jour- 
nal of Mineralogy, by Dr. Bruce, in 1816 ;—these are among 
the most prominent events, which, in the course of a few 
years, have totally changed the face of this science in the Uni- 
ted tes. 
During the last ten years, it has been cultivated with great 
ardour, and with great success : many interesting discoveries 
in American mineralogy have been made; and this science,
