The salts found by C. SCHMIDT in the lymph of the horse have the fol- 

 lowing composition, calculated in parts per 1000 parts of the lymph: 



Sodium chloride 5 . 67 



Soda 1.27 



Potash ; 0.16 



Sulphuric acid . 09 



Phosphoric acid united with alkalies . 02 



Earthy phosphates . 26 



In the cases investigated by MUNK and ROSENSTEIN the quantity of 

 solids in the fasting condition varied between 35.7 and 57.2 p. m. This 

 variation was essentially dependent upon the extent of secretion, so that 

 the low amount coincides with a more active secretion, and the reverse 

 in the other case. The chief portion of the solids consisted of proteins, 

 and the relation between globulin and albumin was as 1;2.4 to 4, 

 The mineral bodies in 1000 parts lymph (chylous) were: NaCl 5.83; 

 Na 2 CO 3 2.17; K 2 HPO 4 0.28; . Ca 3 (PO 4 ) 2 0.28; MgsCPOJa 0.09; and 

 Fe (P(>4) 0.025. CARLSON, GREEN and LUCKHARDT 2 have recently made 

 comparative estimations of NaCl in blood-serum and lymph of the same 

 individual (horse and dog) and find that the lymph is regularly richer in 

 chlorides, a condition which, according to them, is difficult to reconcile 

 with the view of the filtration and transudation processes in the forma- 

 tion of lymph. 



Under special conditions the lymph may be so rich in finely divided 

 fat that it appears like chyle. Such lymph has been investigated by 

 HENSEN in a case of lymph fistula in a ten-year-old boy, and by LANG 3 

 in a case of lymph fistula in the upper part of the left thigh of a girl of 

 seventeen. The lymph investigated by HENSEN varied in the quantity 

 of fat, as an average of nineteen analyses, between 2.8 and 36.9 p. m.; 

 while that investigated by LANG contained 24.85 p. m. of fat. 



The quantity of lymph secreted must naturally change considerably 

 under various conditions, and there are no means of measuring it. The
