16S Miscellanies. 
We notice also, with pleasure, a valuable horticultural Repository, 
published monthly in New York, and various occasional addresses, 
containing interesting facts and details: that of Dr. J. W. Francis, 
delivered in September, in New York, is a rich and elegant docu- 
ment; and that of Mr. G. W. Clinton, pronounced at Canandaigua, 
in the preceding June, exhibits a vigor and spirit for improvement, 
creditable to the writer, and the fine region of western New York. 
Among the publications that commemorate the productions of our 
great gardens, those of the Messrs. Prince, possess much interest 
and value. 
29. Literary and scientific societies of Canada.—We have had 
occasion, repeatedly, to notice the promising and already successtul 
efforts which are making to promote science in Canada. We under-

the Transactions of the Literary and Historical Society of Quebec, 
may be soon expected. 
The last report which we have seen of the Natural. History Soci- 
ety of Montreal, dated May 31, 1830, exhibits a sound and vigor-

liberal direction. 
We wish all success to our intelligent neighbors in their merito- 
rious efforts, which it will be always a pleasure to promote in any 
way in our power. 
30. Affinity of the Diallage family, in chemical constitution, with 
augite.—Fr. Kéhler has given (Poggendorff, Ann. XI. 101) the 
results of a mineralogical and chemical examination of the species 
Metalloidal Diallage, Bronzite and Hypersthene, from which he 1 
fers their general identity with augite; to which species he refers 
them, under the denomination of the Schiller spar family. (Ze 
schrift fiir Mineralogie, Nro. 5. Mai. p: 386.) _ 
31. Collections of Insects —M. J. L. Laporte, of Bordeaux 
in a letter to Dr. J. Porter, of Plainfield, Massachusetts, states, that 
he is engaged in a work upon the insects of both Americas, and that 
he is therefore anxious to receive insects of every species from al 
parts of North and South America. He requests particularly thet 
the butterflies may be put up in paper triangles, that they may 4 
rive in the best state. He promises liberal returns in insects from
