JVovember. — Capt. Delafield, of the U. S. Engineers, presented 

 fossil crabs and shells from the dry dock excavation, Gosport, Va. ; 

 and Mr. G. Gibbs, of Turks Island, a collection of choice specimens 

 of Echini and other radiary animals, together with zoophytes and 

 shells from the Bahamas. 



Information was received through the President, that Dr. Thom- 

 son, of Glasgow, has continued his analyses of American minerals, of 

 which a part have already appeared in the Annals of the Lyceum. 

 Prof. T. announces that the radiated tremolite of Corker's Hook is 

 hydrous AnthophyUite ; the Scapolite of Bytown, Canada, is a vari- 

 ety of pyroxene, which he calls JllaUte ; and he gives the name of 

 Perthite to a new mineral from Perth in Upper Canada. 



3. Academy of JVatural Sciences of Philadelphia. — Since the no- 

 tice of this institution in our last number, its collections have received 

 some munificent additions. The first of these is from Dr. Burrough 

 of Philadelphia. This gentleman has recently returned from a voy- 

 age round the world, in the progress of which he visited some of its 

 most interesting regions. The scientific zeal and industry evinced 

 by him on these occasions have few examples on record. South 

 America, India, and the intervening ocean, were all laid under con- 

 tribution, and he has returned to his native country, freighted with 

 the treasures of nature. Among these are extensive collections of 

 birds, quadrupeds and shells, together with smaller ones of the sub- 

 ordinate classes of animals. Some of these productions have never 

 before reached this hemisphere, among which we may mention, as a 

 prominent object, the Thibet ox, one of the rarest of its kind. Dr. 

 B. also obtained, by unwearied personal exertion, the complete skel- 

 eton of an adult Rhinoceros. 



This varied series of organized beings, has been deposited with a 

 munificent hberality, in the Academy of Natural Sciences, in which 

 no expense or labor will be spared, to have them arranged and dis- 

 played in a manner equally consonant with elegance and usefulness. 



In addition to the former splendid collection of birds, plants, &£c. 

 received from Dr. Hering of Surinam, the Academy has more re- 

 cently to thank that indefatigable naturalist, for some valuable addi- 

 tions to their cabinet. These consist of a very extensive series of
