The analysis of Eupyrchroite, described by Dr. Emmons in the 
second annual report, proves it to be a phosphate of lime 92.85, 
with oxide of iron 5.26 and a trace of fluoric acid; and Rensse- 
__ laerite is “ pyroxenic steatite ;” its crystalline form is the oblique 
thombic prism, M on M 94° and 86°, P on M 106° 30’; and 
resembles the steatitic pyroxenes of Sahla noticed by Beudant, 
and its composition, 59.75 silica, 32.90 magnesia, is similar to 
that of steatite. 
Dr. Torrey’s report on Botany, is the first of importance re- 
ceived from him. He is charged with the collection and preser- 
vation of séven sets of each species, and the arrangement and 
naming of the whole. From the nature of his duties, the assist- 
ance of many observers and collectors in various portions of the 
State, was indispensable, and they seem to have placed at his 
disposal, with truly scientific liberality, their catalogues and col- 
lections, for the ‘purpose of enabling him to make out his own 
catalogue. . 5 
“'The whole number of species, indigenous and naturalized, in 
the State, including the lower orders of the cryptogamia, proba- 
bly exceeds 2,400. Of the phenogamous, or flowering plants, 
1,350 species have been found; of ferns and plants allied to 
them, 53 species ; of the mosses, 150 species; of Hepatice and 
Characex, 30 species ; lichens, more than 150; and fungi, at least 
300. Of the flowering plants, 277 are trees or shrubs ; 150 are 
Teputed to possess medicinal properties ; 250 are ornamental herba- 
ceous species; and 140 are plants whieh have been introduced 
from other countries, and are now naturalized in our soil. O 
Proper grasses, our Flora contains 150 species, twenty four of 
Which are of foreign origin. In ‘the nearly allied tribe of the 
sedges, there are 140 species, more than half of which belong to 
the genus Carex.” 
‘The natural method is employed in the catalogue, with the 
synonyms, locality, time of flowering, &c.; and the final report 
will contain full descriptions of all these plants, and of others 
that before its publication may be discovered and added to this 
catalogue of 81 pages, 8vo. 
» Mr. Conrad’s report is short, and occupied in detailing the prog- 
tess he has made in identifying the New York strata as equiva- 
lents of Murchison’s “ Silurian System.” The view he took of 
these in his first report, has been completely confirmed by more 
careful comparison of the organic remains; and it is impossible,
