The form of the “Conversations” is generally considered as de- 
tracting from its merits and utility, and any attempt at improvement 
in books for elementary instruction is recommended by the previous 
familiarity and experience of the author, which in the present in- 
stance give the work claims to public notice. 
6. Lyceum of Natural History, New York.—This Society, since 
our last notice of its proceedings, has been actively engaged in en- 
deavors to extend its resources, and enlarge its prospects of future 
usefulness, which appear likely to result in speedy and gratifying 
success. The friends of science in New York have come forward to 
aid it, by subscription to shares of a stock, formed by the Society, 
which has already enabled them to purchase ground in a command- 
ing and desirable spot, where, when the subscription is completed, a 
building adequate to all the purposes of the Lyceum will be erected ; 
in which their valuable and rapidly increasing Museum can be efficient- 
ly displayed; courses of lectures on scientific subjects delivered; and 
where the students, and friends of natural science, may find a ren- 
dezvous not unworthy of this great metropolis. The following are 
Some extracts from their minutes.

Dr. Harlan communicated information received from Dr. Troost,. 
of the discovery of the remains of the Megalonyx in a cave in Ten-

as having been found in White Cave, Kentucky, he has since ascertain-
