    (more especially Case 4) the whole mucous membrane of the affected part appeared rough and irregular,as if ulcerated, and innumerable parasites lay upon and in it. The mature females could easily be distinguished, not only by their larger size, but by the opaque whiteness of their bodies. The majority of the female worms examined were im- mature, and did not contain developed ova. The males were not nearly so numerous as the females. Forms inter- mediate between the adult worms and the young embryos (some of which, as already mentioned, existed free in the mucus) were not met with. “ The occurrence in the bronchial tubes of the lower animals of nematoid worms belonging to the genus strongylus is by no means uncommon. Owing to the irrita- tion caused by their development in the mucous mem- brane an inflammation of the tubes is produced, hence the affection is known by the names of parasitic or verminous bronchitis, popularly called ‘ husk ’ or ‘ hoose.’ It is not altogether unknown in man, but very few instances are on record. Infesting the domestic animals there are three well-recognised species of strongylus : the S. filaria of the sheep and goat; S. paradoxus of the pig ; and S. micrurus of the calf, more rarely of the horse and ass. In calves and lambs parasitic bronchitis often constitutes a serious and fatal epidemic, so much so that in the latter it goes by the name of the lamb disease. So far as I know, no epidemic of the kind has been noticed in Canada. The species I have here described differs in several particulars from either of the above mentioned, and is most probably new to science. “ The origin of the epidemic must, I am afraid, like that of so many other diseases, remain obscure. We have abso- lutely nothing to aid us in forming an opinion on the sub- ject. There had been no change in the locality nor in the food. The straw upon which the dogs slept was of the ordinary kind, and the usual attention had been paid to
