SUMMARY OF CURRENT RESEARCHES RELATING TO 
formation of the embryo and the multiplication of the corpuscles are 
cotemporaneous it is because they are associated with one another. 
The corpuscle remains inert in the liquids of the egg, and only begins 
to make use of them when they have become lit for the evolution of the 
embryo. This is very much the same as the latent microbism of 
M. Verneuil, but the position is more strictly defined. 
Endoglobular Parasites of Blood of Dog.* — Sig. G. P. Piana and 
Sig. B. Galli-Valerio had an opportunity of examining the blood of a 
dog which sickened with fever weakness and slight jaundice, after a 
day’s hunting in a marshy locality. In 3-4 per cent, of the blood-cor- 
puscles the authors found pyriform bodies 3’5— 2*5 /x in size, with a 
small oval or round figure in the interior. They stained well with 
methylen-blue, but showed in their interior a small white spot. When 
treated with quinine the pyriform bodies disappeared, and the dog got 
well. The authors consider the pyriform bodies to be Protozoa, and 
very similar to those described by Smith and Kilborn in Texas fever. 
They name them Pyrosoma bigeminum var. canis. 
Flagellata in the Intestinal Canal of Man.f — Dr. B. Schiirmayer 
records the case of a child one year old, which was seized with cramps, 
vomiting, and diarrhoea. The stools were typhoid-like, and had an acid 
odour. Microscopical examination of fresh and stained preparations of 
the stools revealed nothing specially characteristic. Cultivations from 
the stools in albuminous media contained, in 24 hours, large numbers of 
Flagellata. Examined in hanging drops, they were found to be 12-14 /x 
long and 4-5 /x broad. At the front end were two thick cilia, longer 
than the body-length. The posterior end was somewhat pointed. At 
the anterior end was a bright round vesicle, the rest of the body being 
filled with a granular plasma. The general form of the adult body was 
spindle-shaped, but while some of the spindle forms had the vesicle, 
others showed a large dark nucleus. Reproduction was effected by 
fission, after conjugation of two individuals, the result being spores 
with spheroidal shape and large nucleus. 
Sporozoa of Vaccine Lymph.J— Prof. M. Ogata has made micro- 
scopical examinations of human lymph, calf lymph, and variola lymph, 
and has found in all three appearances so similar that he comes to the 
definite conclusion that the three diseases are caused by the same para- 
site. Though there are slight differences in the form of the parasites 
these are probably due to differences in the growth stages, or of the 
host. The parasite itself is declared to be the Gregarinid Clepsidrina. 
In human lymph it manifests itself as a nucleated and non-nucleatcd 
body, as cysts of various descriptions, and as wormlike bodies. The 
parasite is found free in the lymph or in epithelial cells. In calf and 
variola lymph the appearances observed were much the same, though 
there were slight differences of colour-reaction and of size. 
The examinations were made with fresh unstained and stained pre-
