carbonate of soda ; sulphate of lime, and traces of salts of po-

According to Vauquelin and Buniva, the liquor amnii of a 

 woman was composed of,

According to Dr Bostock, the constituents are, 

 Water, . 97-34 



Albumen, . 0-16 



Uncoagulable matter, 1-10 



Salt, . 1-40

Four specimens of liquor amnii examined by Dr Rees, ex- 

 tracted from four individuals in the 7J month of gestation, con- 

 tained the same constituents. Specific gravity from 1-0086 to 

 1 -007. They all contained urea as a constituent. The caseous 

 matter floating in the liquid contained cholesterin. The salts are 

 the same as those of blood. The following table shows the con- 

 stituents of one specimen :

Fromherz and Gugert did not attempt a quantitative analysis of 

 liquor amnii, but merely to determine the different constituents 

 which it contained.
