corresponding in their meas snt with Heulandite. But, ac- 
cording to Prof. Hitchcock, en differ from Heulandite in the 
proximate measurement of planes Mon T about 10° (or 120° in- 
stead of 130°) as determined by the measurement of three differ 
ent crystals with the common gonior It must be confessed, 
that the comparison of one set of che 
other corroborative evidence,—especially wh en, as in the present 
instance, the crystals are too small to admit o , | 
of the common goniometer, does not authorize the makin ing of a 
new species. Having received a few crystals of this mineral 
from Prof. Hitchcock, I also requested Mr. Teschemacher to 
- measure them. The resui? showed the same agreement with 
the recorded measurements of W. Phillips, and has therefore 
established the true nature of this mineral beyond any doubt. 
I would remark that crystals, precisely like those described by 
Prof. Hitchcock, have lately been found in gneiss on New York 
island; and apparently in the same rock associated with phos- 
phate of lime at Suckasunny, New Jersey.* There can be no 
doubt, I think, that the radiated or fasciculated mineral accompa- 
nying these crystals is stilbite, and not a variety of Lincolnite or 
Heulandite, as Prof. Hitchcock supposes.

Ar the same time that Dr. Johnson attacked the “collector of 
shells and stones,” and other objects of natural history, with his 
raillery and wit, he was compelled to acknowledge that there was 
“nothing more worthy of admiration to the philosophical eye, 
than the structure of animals, by which they are qualified to sup- 
port life in the elements or climates to which they are appropria- 
ted.” And, indeed, the most gifted minds have contemplated 
* Among some specimens which I have lately received from Copenhagen, 
through a distinguished friend of science, Compte de Vargas Bedemar, I observ 
precisely the same modified crystals with those of Lincolnite, but no near ap- 
proach to the form of Beaumontite. These specimens are from Faroe, a region | 
which the Count has personally examined. -
