110 Mr. Gulliver’s Ohsermtiojis 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 1 -4000th 
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 ArctoSi) female, hardly a 
third grown. Most frequent diameters of corpuscles l-3600th, 
l-3692nd, 1-S750th, l-3790th, and l-4000th. Extreme sizes 
J -4570th 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 : l-3600th, l-3693rd, 
1-S790th, 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, ( JJrsus Americanus, var.?) 
a male, from North America, apparently of the same age as the 
Black and European Bears. l-3693rd, l-3790th, l-3840th, 
l-4000th, all common sizes. Extreme diameters l-4800th 
and l-3000th. Blood from a prick of the upper lip. 
89. Polar Bear, [Ursus Maritimus,) an old female. The 
following sizes very common : l-3600th, l-3693rd, l-3764th, 
and 1- 3840th. Extreme diameters l-4570th and l-3048th. 
There were seen, though rarely, some as small as I -53 33rd 
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 
1 -4000th to 1 •'3555th. Extreme sizes 1 -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, {Procpon lotor,) nearly full-grown male. In 
the dried corpuscles, the following sizes all very common ;
