ACCLIMATIZATION. 
the wall of an unopened vessel so that its ends may lie in the 
blood, it is found on examination, after a certain time has 
elapsed, that the needle is surrounded with an encrusting 
clot. It is scarcely necessary to point out how entirely the 
ammonia theory and the oxygen theory, as well as that of 
rest, fail to account for facts like these. 
While the blood may remain fluid for forty-eight hours in 
the jugular vein of a horse or an ox, it coagulates soon after 
death in the heart of very small animals, such as mice; so 
that it is obvious that the continuance of the fluidity in 
small vessels is not due to their small size.

ACCLIMATIZATION. 
We continue our promised condensation of Mr. J. Ince’s 
papers in the Pharmaceutical Journal , in which he thus 
describes the Garden of Acclimatization of Paris : 
“ A garden of acclimatization differs essentially from 
either the zoological or the botanical garden, nor is it the 
result of the two combined; for whereas both these latter 
are meant to be the living text-books of the subjects to which 
they are specially devoted, and are just so far perfect as they 
contain accumulated illustrations of their respective studies, 
a garden of acclimatization, having no technical boundary 
line of science, selects from all living objects whatever of 
either use or beauty may be deemed worthy of home intro¬ 
duction. Its range is from the yak to the silkworm, and 
from the lama to the sponge; to quote its own announce¬ 
ment, ‘ its great object is to acclimatize, to multiply and to 
distribute to the public, animal or vegetable species which 
are or may be hereafter newly introduced into France, and 
may seem worthy of interest from their usefulness or 
ornament/ 
“ For France read Europe, and then w r e shall clearly 
understand the scheme. In the remarks about to follow, I 
have been painfully hampered by the difficulty of compressing 
discursive details into journal space; the w 7 hole zoological 
section has been necessarily omitted, w 7 hile at the same 
time many of the topics here barely mentioned form the 
basis of successive lengthy papers in the official ‘Transactions’ 
of the society. Enough, however, is brought forward to 
guide the steps of future students, and possibly to stimulate 
their interest; and if all,the hidden gold has not been dug
