Abstract
The eggs of Fasciola gigantica are laid by the flukes in the bile ducts of the liver, passed with bile to the gall bladder and thence to the intestine and they are finally deposited with the faeces of an infested animal. It has been found that the eggs in the gall bladder are at the earliest stage of their development, when the embryo is represented by a single cell. In many eggs recovered from the gall bladder the sperm nucleus and the nucleus of the egg can be seen lying side by side in this single cell ready to fuse and thus complete the process of fertilisation of the egg.
