Our results on the cow and sheep confirm the observations of Doderlein, as is shown

We further find — what Doderlein did not record — an excess of phosphorus and 

 sulphur compounds in the allantoic fluid. Our single examination of the fluid in the 

 pig does not show the differences in the magnesium and calcium contents of the fluids 

 which are observed in ruminants. 



Doderlein lays great stress upon the distribution of these inorganic constituents, 

 maintaining that the high content of the amniotic fluid in chlorine and sodium indicates 

 its origin as a transudate from the plasma, and that the large amount of magnesium 

 in the allantoic fluid indicates its origin from the kidneys. But Vierordt 



* These results should be lower, as in some cases he gives " traces."
