GENERAL INDEX. 



331 



Corpuscles, red, of the blood, (continued.") 

 each portion of the divided vesicle 



red, xlvi, 226. 

 run into rolls in mammalia, 228, but 



not so regularly in the Camelida3 



and in the lower vertebrata, 228. 

 supposed not to alter their shape, 



when circulating in a narrow vessel 



228, but they do, being very pliant 

 and elastic, 228-9. 



the forms which they assume, 229. 

 their flatness preserved by the salts 



of the serum, 229, 231. 

 shrivelled by strong saline solutions, 



229, 232. 



effects of weak solutions and of urine 

 on, 229-31 ; the salt keeps the 

 corpuscles from running together, 

 229, 231 ; and alters their shape 

 variously, 229-32. 



effects of various salts on, 230-31. 



effects of acids and alkalies, 230-31. 



effect of spirits of wine, 231. 



differ in size and in chemical pro- 

 perties in the same animal, 232-3, 

 236. 



differ in size and form at different 

 periods of life, 233. 



their size and shape in fishes, ten- 

 derness of the envelope, and shape 

 of the nucleus, 234. 



wanting in the amphioxus, 234, 273. 



general diffusion of in the animal king- 

 dom, 209, 211, 235. 



supposed to convert albumen into 

 fibrin, 235. 



supposed to be formed by certain 

 organs, 236, 273, 275. 



supposed uses of, 212, 235-6. 



differ in chemical properties from 

 pale cells, 235, 254. 



supposed separation of the envelope 

 during the formation of fibrin, 

 xli, 235-6. 



alter in shape or size if they come 

 with difficulty from a minute prick, 

 236. 



of mammals larger when quickly dried 

 than when kept moist, 236-7. 



of birds and reptiles, smaller in the 

 dry state than when wet, 237. 



shape of in birds and reptiles, 218-19, 

 312. 



on the formation of, from the pale 

 globules of the blood, 254. 



in the splenic lymph, 273. 



on the manner in which they are 

 formed, 274. 



vesicle and nucleus of, 274 ; and ad- 

 hesion between them, 275. 



Corpuscles, red, of the blood, (continued.} 



the nucleus temporary in mammals and 



permanent in lowervertebrata, 275. 



differ in figure and size in different 



animals, 275, 279-19. 

 vesicles of, supposed to have nuclei in 

 all animals, 275. 



the corpuscles supposed to be formed 

 by the lymphatic system and its 

 appendages, 275. 



in the lymphatics, 276, 277 ; and in 

 the thoracic duct, 276 ; but not so 

 perfect as those in the blood, 277. 



supposed formation of, from chyle or 

 lymph-globules, xlvii, 254, 277. 



red envelope of, formed in the lym- 

 phatics emerging from a lymphatic 

 gland, 277 ; and in the spleen, 

 282-6. 



lymphatic vessels and glands may 

 form the red part of the blood ,277. 



formed in lymphatic vessels indepen- 

 dently of the glands, 278, 284. 



nuclei in those of the spleen of a 

 bird, 283. 



from the heart and spleen compared, 

 283. 



envelope of, see Envelope. 



HEWSON'S letter to Dr. HAYGARTH 

 concerning, 287. 



in birds, the shape of the nuclei com- 

 pared with that of the lymph- cor- 

 puscles, 253, 279. 



nuclei of, formed in the thymus and 

 lymphatic glands, 289. 



figure of a narrower ellipse in the 

 slow-worm than in the snake or 

 adder, and examples of a difference 

 of shape in the corpuscles of other 

 nearly allied animals, 312. 

 Corpuscles in the fluid of the lymphatic 

 glands described, 253. 



compared to the nuclei of blood-discs, 

 253. See Nucleus. 



do not vary in size and shape like 

 those discs in different animals, 

 and differ in figure from the nucleus 

 in the blood-disc of birds, 253. 



their size in the musk-deer, 253. 



of the usual round shape in the ca- 

 melidffi and in birds, 253. 



smaller than the pale globules of the 

 blood, 253. 



insoluble in water, 253. 



their structure and chemical charac- 

 ters, 253-4. 



differ in chemical properties from the 

 red corpuscles of the blood, 254. 



considered as nuclei or immature 

 cells, 254.
