196 B, T. LOWNE ON THE FLAMINGO. 



which the corpuscles might pass through the capillary walls by an 

 alteration in their form. 



Even if the process in the flamingo is an unhealthy one, it may 

 still afford some evidence on this interesting point. In that case 

 it may be considered analogous to the excretions of blood-stained 

 sweat from the skin. Although cases of this kind are rare, yet 

 they are well authenticated in man. 



Mr. Bartlett assures me that the hippopotami in the Zoological 

 Gardens frequently exude blood-stained sweat when furious, and 

 the same gentleman told me a very curious and interesting story 

 about a pair of rhinoceri which Mr. Jamrack, the celebrated dealer 

 in beasts, once bought, I think at Calcutta. It appears that the 

 poor animals suddenly conceived a desire to see their native forests 

 once more. They both escaped and rushed wildly away from their 

 keepers, who did not overtake them for a long time — something 

 like twelve hours, I believe — and when they did they found their 

 hides covered with blood, which did not issue from any wound, but 

 from the whole surface. A few hours after both died.
