26 Mr. G. Gulliver's Observatio?is on the Blood Corpuscles 



digestion ; but, in their deep-red colour and chemical pro- 

 perties, they differ remarkabl}' from the granules observed in 

 the chyle. 



1. Dog-faced Baboon, hardly half-grown, [Simia Cynoce- 

 pJiahis). Blood from the right ventiicle of the heart. Cor- 

 puscles generally 1-31 92nd of an inch in diameter; extreme 

 sizes l-4<000th and l-2666th of an inch, the largest more fre- 

 quent than the smallest. 



2. Greenyionkey, ?i^\x\{,[CercopithecusSabceus). Average- 

 sized corpuscles l-f^;200th to l-3000th of an inch in the dry 

 state, l-3600th in their own serum. Extremesizes l-4000th and 

 l-2666th. Thickness of the corpuscles as seen on their edges 

 1-1 2,000th to l-10,000th of an inch, i. e. a rouleau of five or 

 six filled two of the micrometer spaces. The blood examined 

 was obtained from both ventricles of the heart, from the vena 

 cava, and vena porta?, no appreciable difference appearing in 

 the corpuscles. 



3. White Monkey, adult, {Macacus radiahis^ albino var.). 

 Corpuscles from the right ventricle generally l-3200th of an 

 inch in diameter. 



4. Rhesus Monkey, old male, {Macacus Rhesus). Size of 

 disks very variable from l-4572nd to 1 -2666th of an inch: most 

 common diameter r3200th. Blood of both ventricles exa- 

 mined. 



a. In a young male the same measurements were obtained. 



5. Capuchin Monkey, adult, {Cebus Capiicitius). Most 

 common diameter of corpuscles l-31-28th and l"3200th of an 

 inch dried; in their serum, exposed to the air some hours, 

 l-4000th was a more frequent diameter. Extreme diameters 

 1 -4572nd and 1-29 10th of an inch. Blood from both ventricles 

 of the heart examined. 



6. Mangabey Monkey, adult male, [Cercocehus j^thiops). 

 Common sizes l-3200th and 1- 3000th. Extreme sizes, also 

 common, l-4000th and 1 -2666th. Blood examined from both 

 ventricles of the heart, from the portal and renal veins. 



7. Grivet Monkey, [Cercocehus griseo-viridi's). Most fre- 

 quent sizes l-3200th and l-3000th. Extreme diameters 

 I -4000th and 1 -2666th of an inch. Blood from both ven- 

 tricles of the heart. 



8. Slow Lemur, full-grown, [Loris tardigradus). Most 

 common size l-3552nd. Extreme diameters l-4000th and 

 l-3000th. Blood from a prick of the fore-hand. 



9. Common Bat, [Vespertilio murinus). Blood from right 

 ventricle. Common diameter of corpuscles 1- 4365th to 

 l-4000th of an inch. 



10. Common Squirrel, adult male, [Sciurus vulgaris). Cor-
