420 Miscellanies. 



Many other such varieties are known, not only of apples, peaches, &c. 

 but of wild trees also, differing in shape of leaf, form of growth, color 

 and size of fruit, &c. and also time of ripening. It was therefore to be 

 expected that these should be like in respect of times of leafing. This 

 may throw some light on the question respecting " acclimating." It may 

 be that species may be brought to bear climates originally ill suited ; not 

 by any especial virtue in the seeds, ripened in any particular climate, but 

 by multiplying seedlings, a few of which, out of multitudes, may have 

 qualities suited to this or that country ; e. g. some to cold, some to drought, 

 some to wet, &c. In some cases, a plant's beginning to vegetate later 

 may secure it from spring frosts, which would destroy a precocious va- 

 riety; in others, earlier flowering may enable a tree to ripen fruit in a 

 climate in which a later would be useless. Further, the experiment 

 shows that the common opinion respecting the commencement of spring 

 vegetation — the rise of the sap from the roots through the trunk and 

 branches to the twigs, is groundless. 



7. Neio York State Reports. — Since our last, seven of these important 

 volumes have made their appearance, and in such quick succession that 

 we have hardly had time to glance at their contents. It is our purpose, 

 as these reports will probably be seen by few of our readers, to give in 

 future numbers of this Journal a somewhat extended notice of each of 

 the great divisions of the work ; and in carrying out this design, we shall 

 have the aid of gentlemen eminent in the several departments, and whose 

 opinions will be received as authority. 



8. Flora of North America, by Drs. Torrey and Gray. — The third 

 part of Vol. II, of this work, was published in February last. It is 

 smaller than any of the preceding parts, comprising only 112 pages, and 

 including merely the remainder of the vast order Composites. The spe- 

 cies of Composites described in this work, amount to one thousand and 

 fifty, (doubtless one tenth of the phenogamous flora of our country,) 

 which are comprised in one hundred and ninety-nine genera. The en- 

 suing portion of the work will close the second volume, and contain the 

 remaining monopetalous exogenous families. 



9. Thracia inequalis. — We are requested by Prof Adams to state, 

 that this shell, which was described in our last July number, is the Pe- 

 riploma trapezoides, Desh. Consequently the name of Thracia ine- 

 qualis must take the rank of a synonym. The species has recently 

 been found in Mobile Bay.
