CHYLE AND LYMPH. 347 



example of the composition of human chyle two analyses will be given. 

 The first is by OWEN-REES, of the chyle of an executed person, and the 

 second by HoppE-SEYLER, 1 of^the chyle in a case of rupture of the thoracic 

 duct. In the latter case the fibrin had previously separated. The results 

 are in parts per 1000.

The quantity of fat is very variable and may be considerably increased 

 by partaking of food rich in fats. I. MUNK and A. ROSENSTEIN 2 have 

 investigated the lymph or chyle obtained from a lymph fistula at the 

 end of the upper third of the leg of a girl eighteen years old and weigh- 

 ing 60 kg., and the highest quantity of fat in the chylous lymph was 47 

 p. m. after partaking of fat. In the starvation lymph from the same 

 patient they found only 0.6-2.6 p. m. fat. The quantity of soaps was 

 always small, and on partaking of 41 grams of fat the quantity of soaps was 

 only about gV f the neutral fats. SCHUMM 3 found in the creamy 

 contents of a chylous cyst of the mesentery, 357.8 p. m. fat and compara- 

 tively large amounts of calcium soaps. 



A great many analyses of chyle from animals have been made, and 

 they chiefly show the fact that the chyle is a liquid with a very changeable 

 composition which stands closely related to blood-plasma, but with the 

 principal difference that it contains more fat and less solids. The reader 

 is referred to special works for these analyses, as, for example, to v. GORUP- 

 BESANEZ'S " Lehrbuch der physiologischen Chemie," 4th edition. 



The composition of the lymph is also very changeable, and its specific 

 gravity shows about the same variation as the chyle. In the following 

 analyses, 1 and 2, made by GUBLER and QUEVENNE, are the results 

 obtained from lymph of the upper part of the thigh of a woman aged 

 thirty-nine; and 3, made by v. SCHERER, is an analysis of lymph from 



^wen-Rees, cited from Hoppe-Seyler's Physiol. Chem., 595; Hoppe-Seyler, 

 ibid., 597. See also Carlier, Brit. Med. Journ., 1902, 175, and T. Sollmann, Amer.
