SUMMARY OF CURRENT RESEARCHES RELATING TO 
outside, cementing particles, excretory granules, &c. ; the nucleus shows 
nine phases, and is highly differentiated ; linin and chromatin increase 
as nucleoli (or “ Binnenkorper ”) disappear ; with changes in the nucleus 
is associated a cleansing of the cell substance from excreta and intrusions, 
a “ defecation process ” which may be very rapid ; perhaps this process 
is antecedent to reproduction, which was not observed. Various particles 
— fiecal, mineral, Ac. — have been misinterpreted in connection with 
reproduction. Rliumbler names the five intruding organisms, Bliyncho- 
gromia variabilis , Bhynchosaccus immigrans, Dactylosaccus vermiformis , 
Ophiotuba gelatinosa , and Dendrotuba nodulosa. All are probably 
Protozoa, but the author does not commit himself to a classification. 
Prof. W. Zopf * describes the plasmodial state of a Myxomycete very 
like Enteromyxa paludosa Cienk., which spreads within the tests of 
Saccammina. 
Double Coccidian Infection.! — M. A. Labbe adds three cases to the 
scanty list of the coexistence in one host of a monosporous and poly- 
sporous Coccidium. It will be remembered that this coexistence in the 
case of young Rabbits led Pfeiffer to his theory of the dimorphism of 
Sporozoa. 
M. Labbe finds a great difference in size between a monosporous and 
a polysporous Coccidium , and he has had no difficulty in distinguishing 
their early stages ; the thick membrane of the polysporous form is a 
simple cuticular membrane in the monosporous ; the former are common, 
the latter rare and never present without the former. The fact of two 
parasites being present in the same organ of one host is not a proof of 
their derivation from one another, and if they are different in every stage 
of their life-history, we must conclude that they are different species. 
Amceba-Enteritis.+ — Drs. Roos and Quincke isolated from two cases 
of chronic enteritis two species of Amoebse which differed both morpho- 
logically and as to their pathogenic action on cats. In one case the 
parasites had apparently been obtained in Sicily, and these were smaller, 
more transparent, and moved more actively than those of the second case. 
They frequently contained a large number of red corpuscles, and rarely 
other foreign bodies in their interior ; whilst the sluggish large Protozoa 
of the second case, which had in all likelihood been picked up in Schleswig- 
Holstein, never had blood, but bacteria or food-particles inside them. 
Even in the resting stage marked differences were observed, and a large 
number of inoculations on cats showed that the first Amoeba was ex- 
tremely virulent and the second harmless. The intestines were much 
ulcerated, and numerous abscesses were found not only in the intestinal 
walls but also in the liver. This organism is called A. coli Losch s. felis ; 
the harmless species A. coli initis, the latter being probably identical 
with A. intestini vulgaris. 
Protozoa in Endometritis.§ — Dr. T. R. Doria found in three cases 
of endometritis bodies which he took to be Amoebse. They were dis- 
covered in the canal, the glands, and in the epithelial cells of the cervical
