PROGRESS OF ZOOLOGY. 
tory congestion is due to the blood-corpuscles acquiring 
adhesiveness such as they have outside the body, in conse¬ 
quence of the irritated tissues acting towards them like ordi¬ 
nary solids. 
I cannot avoid expressing my satisfaction that this inquiry 
into the coagulation of the blood has furnished independent 
confirmation of my previous conclusions regarding the nature 
of inflammation. 
THE PROGRESS OE ZOOLOGY. 
By Shirley Hibberd. 
[Continuedfrom p. 348.) 
In the Biblical narrative there are numerous evidences of 
the abundance of beasts of prey in Palestine and Phoenicia, 
where there is now scarce anything more rapacious than a 
fox to be found. David’s adventure with the lion and bear 
could not now be repeated by any brave shepherd within a

kingdom under tribute to furnish him with meat and labour, 
and entertainment and knowledge, but he busies himself to 
disturb the balances, and the gamekeepers of this country 
might be collectively described as destroyers of the British 
fauna. The relations of Sir Emerson Tennent and Dr. 
Livingstone make it pretty evident that the “ half-reasoning 
elephant ” is fast passing from the face of the earth to be 
numbered among the extinct animals by the naturalists of a 
century hence. When we read of the wanton slaughter of 
thousands of elephants, with no object but the gratification 
of the passion for destruction, we are tempted to lament that 
man possesses such complete dominion to subjugate, and 
such unlimited power to destroy. “ Had the motive,” says 
Sir Emerson Tennent, (e that invites to the destruction of the 
elephant in Africa and India prevailed in Ceylon,—that is, 
had the elephants there been provided with tusks,—they 
w r ould long since have been annihilated for the sake of their 
ivory. But it is a curious fact that, whilst in Africa and 
India both sexes have tusks, with some slight disproportion 
in the size of those of the females, not one elephant in a 
hundred is found with tusks in Ceylon, and the few that
