Abstract
ALTHOUGH the second ecdysis of certain species of nematodes which parasitize sheep is known to take place in the alimentary tract of the host, the actual site is not definitely known. In the horse, some knowledge of this subject has been gained by placing larvæ in fluid from various parts of the intestinal tract1; but this method has not always been successful with sheep. However, it has been reported that the abomasal fluid plays a part, at least in so far as Haemonchus contortus 2, Trichostrongylus colubriformis 3 and T. rugatus 3 are concerned.
