110 Mr. Gulliver's Observations on the Blood Corpuscles 



In the venous blood of the monkey tribe, besides lymph 

 globules of the common size and appearance, there are ge- 

 nerally spherical bodies of a very white colour, and fre- 

 quently of semi-fluid consistence, as may be inferred from 

 their being seen occasionally to alter in shape, like a drop of 

 any viscid matter subjected to currents of particles on its mar- 

 gins. The white round bodies vary in diameter from l-'iOOOth 

 to 1-1 777th of an inch. Their number is often very great, 

 and they may be observed very remarkably in blood from the 

 mesenteric veins. In the blood of the right ventricle they 

 are also extremely common, though the semi-fluid appearance 

 is more frequently seen in the former. These observations 

 were made on monkeys, apes, and baboons, dead of various 

 diseases, chiefly tubercular phthisis. Tubercle seems in these 

 animals to be as common in the spleen as in the lungs ; in- 

 deed, this deposit is not unfrequent in the former organ when 

 none can be found in the latter. 



86. European Brown Bear, {Ursus Arctos,) female, hardly a 

 third grown. Most frequent diameters of corpuscles 1-S600th, 

 l-3692nd, 1 -3750th, l-3790th, and l-4000th. Extreme sizes 

 ]-4'570th and l-3048th. Blood from a prick of the upper lip. 



87. Black Bear, {Ursus Americanus,) a male, nearly same 

 size and apparently of the same age as the European Bear. 

 All the following diameters common : 1 -3600th, 1 -3693rd, 

 l-3790th, 1 -3840th. Extreme sizes l-4570th and l-3000th 

 of an inch. Blood from a prick of the upper lip. 



88. Cinnamon or Chocolate Bear, ( Ursus Americanus, var.?) 

 a male, from North America, apparently of the same age as the 

 Black and European Bears. l-3693rd, 1 -3790th, l-3840th, 

 l-4000th, all common sizes. Extreme diameters l-4800th 

 and l-3000th. Blood from a prick of the upper lip. 



S9. Polar Bear, [Ursits Maritimus,) an old female. The 

 following sizes very common : l-3600th, l-3693rd, l-3764th, 

 and I- 3840th. Extreme diameters l-4570th and l-3048th. 

 There were seen, though rarely, some as small as l-5333rd 

 of an inch. Blood from a prick of the upper lip. 



90. Sloth Bear [Ursus labiaius,) an aged female and a full- 

 grown male. Most common diameter of corpuscles from 

 l-4000th to 1 -3555th. Extreme sizes l"4800th and l~3000th 

 of an inch. Blood from the different cavities of the heart of 

 the female ; from a prick of the lip of the male, which was a 

 healthy animal. The unsatisfactory result of the examination 

 of the corpuscles in the female has been already noticed ; the 

 specimen from the male was not a very good one. 



91. Raccoon, (Procj/o?i /o/or,) nearly full-grown male. In 

 the dried corpuscles, the following sizes all very common:
