64 REMAINING CONSTITUENTS OF THE RED BLOOD-CORPUSCLES. 



THE REMAINING CONSTITUENTS OF THE RED BLOOD- 

 CORPUSCLES. 



The red corpuscles contain further: Lecithin, 1.867 P er cent, in dry 

 erythrocytes; urea, equally divided between erythrocytes and serum; 

 cholesterin, 0.151 per cent.; no fats; lactic acid, in the dog. 



Lecithin and cholesterin can be obtained by agitating considerable amounts 

 of stroma or isolated blood-corpuscles with ether. If the ether is permitted to 

 evaporate the characteristic globular myelin-forms of lecithin and the crystals 

 of cholesterin will be recognized. 



Water, 631.63 in the thousand. 



After abstraction of considerable quantities of blood the amount of water 

 diminishes and the amount of dry substance, as well as the nitrogen of the ery- 

 throcytes, increases. The opposite effect is brought about by infusion of physio- 

 logic salt-solution. 



Inorganic matters, 7.28 in the thousand, particularly combinations 

 of potassium and phosphoric acid. The phosphoric acid is derived 

 only from consumed lecithin, the sulphuric acid in large part from the 

 hemoglobin consumed in the analysis. Some manganese also is 

 present. 



Blood-analysis. One thousand parts by weight of horses' blood are made up 

 as follows : 



344.18 parts blood-corpuscles, with 128 of solids 383 in the dog, 

 655.82 parts plasma, with 10 per cent, of solids 617 in the dog. 

 One thousand parts by weight of moist blood-corpuscles are made up as 

 follows : 



Solids, 367.9 (swine), 400.1 (cattle), 435 (horse), 



Water, 632.1 (swine), 599.9 (cattle), 565 (horse).

CHEMICAL CONSTITUENTS OF THE LEUKOCYTES. 



Leukocytes from the plasma of lymphatic glands, as well as pus- 

 corpuscles contain proteids as follows: little albumin, alkali- albuminate 

 and an albuminate resembling myosin and coagulating at 48, two 

 globulins coagulable at 48.5 and 75 C. respectively, together with 

 serum-globulin, peptone and a coagulating ferment, further consider- 

 able nucleins from the nuclei, nucleo-histon, little glycogen, lecithin, 

 cerebrin, cholesterin, fats, protagon, inosite, amidovalerianic acid. 



Lymphocytes contain 11.5 per cent, of dry matter. In 100 parts by weight 

 of dry pus there are 0.416 earthy phosphates, 0.143 sodium chlorid, 0.606 sodium 

 phosphate, 0.202 potassitmi, in part in the form of monopotassium phosphate.
