The foregoing paragraphs contain the leading features of all the information which I have been able to glean with reference to the existence of hsema- tozoa in dogs: I could find no allusion whatever to any such condition being manifested by dogs in India. Whilst making a microscopic examination of some gland tissue from the mesentery of a to^oaTnVpwiah dlg™fn pariah dog (last July), I observed that the sanguineous fluid squeezed out of the preparation on the slide contained numerous minute nematode worms in a state of great activity, and pre- senting at first sight a marked resemblance, both as to the character of their movements and their size, to the hsematozoon referred to above as existing in human blood. I had for a long time been desirous of obtaining living specimens of a canine heematozoon so as to be able to institute a comparison between this kind and those found in man, although I had not entertained any very sanguine hope of being able by this means alone to pro- nounce definitely as to the identity or otherwise of the two parasites, for it has long been known that the em- bryos of many filarise of widely differing size and habitat present no appreciable difference either of size or form :
