Doderlein (loc. cit., p. 149) found in the cow a marked and rapid increase in 

 the amniotic fluid in the first half of pregnancy, and then a very marked fall 

 towards the end ; and an almost continuous increase in the allantoic fluid — an increase 

 which became more marked in the second half of pregnancy, when the amniotic fluid 

 was decreasing. 



We have been unable to procure the original papers of Majewski (De substantia?* um 

 quse liquor ibus amnii et allantoidis insinit: Dissertatio, Dorpat, 1858) on herbivora, 

 or those of Tschernow (De liquorum embryonalicum in animalibus carnivoris : 

 Dissertatio, Dorpat, 1858), referred to by Doderlein, p. 145.
