tion of a yet unknown hasmatozoon, inhabiting the portal vein or 
hepatic artery, and allied perhaps to Bail let’s Strongijlus vasorum 
found in the larger divisions of the pulmonary artery of dogs, and 
causing a very similar infection of their lungs. One more point in 
the literature of the subject remains to be noticed, and this is that 
]\lazzanti* speaks of the embryos as having been carried to their 
destination by a capillary which occupies the centre of the nodule. 
I have not been able to find any trace of this capillary, the only 
thing I have met with at all like it within them, being sections of 
the embryo itself, which occasionally present a deceptive resemblance 
to those of a small vessel. In conclusion I would wish to point out 
that the micropbotographs illustrating this note are intended to show 
general relations only, as I have purposely avoided entering into any 
minute details of the micropathology of the tissues surrounding the 
parasites described.
