CHYLE, LYMPH, TRANSUDATIONS AND EXUDATIONS. 119 



according to PFLUGER and STRASSBURG, smaller than in venous but 

 greater than in arterial blood. 



The quantitative constitution of the chyle must naturally be very 

 variable. The analyses thus far made refer only to that mixture of 

 chyle and lymph which is obtained from the thoracic duct. The 

 specific gravity varies between 1.007 and 1.043. As example of 

 the constitution of human chyle we will here give two analyses. 

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

 the second by HOPPE-SEYLER, 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 1000 parts.

The quantity of fat is very variable and may be considerably in- 

 creased by partaking food rich in fats. 



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 chief difference that it contains more fat and 

 less solids. The reader is referred to special works for these 

 analyses, as, for example, to v. GORTJP-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 QUEVESTNE, 

 are the results obtained from lymph from the upper part of the 

 thigh of a woman aged 39 ; and 3, made by v. SCHERER, is an analysis 

 of lymph from the sac-like dilated vessels of the spermatic cord. No.
