proteids. Among the albuminous bodies WEYL found one sub- 

 stance similar to vitellin and with great probability also serum 

 albumin, besides small quantities of mucin. Glucose is regularly 

 found in the amniotic fluid of cows, but not in human beings. On 

 the contrary, the human amniotic fluid contains some urea and 

 allantoin. The quantity of these may be increased in hydramnion 

 (PROCHOWNICK, HARNACK), which depends on an increased secre- 

 tion by the kidneys and skin of the foetus. Creatin and lactates 

 are questionable constituents of the amniotic fluid. The quantity 

 of urea in the amniotic fluid is, according to PROCHOWNICK, 0.16 

 p. m. In the fluid in hydramnion PROCHOWNICK and HARNACK 

 found respectively 0.34 and 0.48 p. m. urea. The chief mass of 

 the solids consists of salts. The quantity of chlorides (NaCl) is 

 5.7-6.6 p. m.
