    In a brief resume of the more generally known The canine hsematozoa discovered in France, hsematozoa among lower animals which was given in the former paper, reference was made to the discovery made by MM. Grube and Dclafond, more than twenty years ago, of microscopic nematode worms in the blood of dogs in Prance.* They were about yi^th of an inch in length with a transverse diameter somewhat less than that of a red blood-corpuscle. Out of 480 dogs examined, from foui.* to five per cent, were found to be thus affected; but on one occasion only were MM. Grube and Delafond able, by post-mortem examination, to detect parasites in the bodies of the animals, visible to the naked eye, which could be looked upon as parents to the microscopic worms in the blood. On the occasion referred to, however, they were able to satisfy themselves on this point by the discovery of six white, filiform worms (four males and two females) in the right ventricle of one of the animals. These were from five to seven inches in length and from ¥15-th to TJ¥th of an inch in width; the anatomical details could be clearly made out, as also the stages of the development of the ova in the ovaries and of the embryos in the oviducts, the embryos being considered identical with the mi- croscopic worms in the blood. In the same paper attention was also drawn to the observations recorded concerning the worms found, frequently and in considerable numbers, in the right cavities of the hearts and. in China, Japan, &c. # Comples llendus, tome XXXIV, 1832.. pp. 11 n.
