Also Bruntons paper on the Chemical Comp. of theNuclei of Blood Corpuscles in Journ. of Anat. and Phys., vol. iv. 1870, p. 91. The distinctivechemical characters of nuclein appear to constitute an answer to Mr. Savorys view that the existence of a nucleus in the red corpuscles of Ovipara is due to changes after death orremoval from the vessels. See his paper in Month. Micr. Journ. 1869, vol. i. p. ITS PHYSICAL, CHEMICAL, AND STRUCTURAL CHARACTERS. 233 that the white corpuscles only contain glycogen as long as they exhibit move-ments, and that when they become rigid they lose their glycogen and containsugar. The white corpuscles of the blood, both of the frog and triton, as well asthose of man, have been observed by Klein to multiply by fission ;* but they areessentially regenerated from lymph corpuscles of lymphatic glands and fromcertain endothelial cells of the serous membranes. The proportion which the white or colourless corpuscles bear to the red, isvery small in the blood of man and the higher Vertebrata ; being, in the stateof health, according to the estimate of Moleschott (which is confirmed byKblliker),}- not more than 2*55 to 1000.
