LYMPH. 419 



The coagulum did not consist of globules, as is the case with 

 the crassamentum of the blood. It had originally been in solu- 

 tion in the liquid, while the globules were suspended in it. The 

 globules separated and contained in the coagulum might be seen 

 scattered through it, and these were much smaller than the glo- 

 bules that still remained in suspension in the liquid. 



Professor Muller gives a method of obtaining pure lymph 

 from the frog. When the skin is removed from the thigh of a 

 large frog, and the muscles laid bare without wounding any 

 large blood-vessel, a clear, colourless, salt- tasted lymph flows 

 out. It contains \ of fibrin. If the frog has fasted long no 

 lymph can be got by this process. The globules in the lymph 

 of the frog are exceedingly small. Lymph in the lymphatic 

 vessels is commonly colourless, in those of the spleen it is reddish. 

 We know little about the motion of the lymph. Muller describes 

 an organ which he considers as connected with that motion.* 



A quantity of lymph from a wound after the removal of the 

 foot was collected and examined by MM. Marchand and Col- 

 berg.f About 1^ gramme was collected in twelve hours. Its spe- 

 cific gravity was 1O37. It gradually deposited a thin web of 

 fibrin, amounting to about half a per cent, of the lymph. The 

 opalescent liquid above it had a yellow colour, and the consist- 

 ence of almond oil. Its constituents, as determined by these 

 Chemists were, 



Water, . . 96-926 



Fibrin, . . 0-520 



Albumen, . (K34 



Osmazome and loss, . 0*312 



Fat oil, | 



Crystalline fat, / 



Chloride of sodium, 



Chloride of potassium, 



Carbonate and lactate of potash, 



Sulphate of lime, , 



Phosphate of lime, 

 Oxide of iron,
