This membrane communicates with the urachus, which in brutes is open, and tranf- mits the urine from the bladder to the allantois. 5. The waters are contained within the amnion, and are called the liquor amnii. They are pureft, cleared, and mod limpid in the firft months ; ac- quiring a colour and becoming fomewhat ropy, towards the latter end. They vary in different lubje&s, both in regard to confidence and quanti- ty ; and, after a certain period, they proportion- < ally diminifh as the woman advances in her preg- nancy. This liquor does not, in any refpect., re- femble the white of an egg ; it is generally faltifh, and therefore unfit for the nutrition of the child ; fome of it may perhaps be abforbed by the foetus, but the child is chiefly nourifhed by the navel firing. In the early months, the organs are not fit for fwallowing ; and monfters are fometimes born alive, where fuch organs are altogether want- ing. Water is fometimes collected between the cho- rion and amnion, or between the lamella? of the chorion. This is called the falfe water : It is gen- erally in much fmaller quantity than the true wa- ter ; and, without detriment to the woman, may Sow at any time of pregnancy. Having
