SUMMARY OP CURRENT RESEARCHES RELATING TO 
partially in nitric acid, shrivelling up in water. (7) Paraglycogen, in 
the granules ; iodine reaction red-violet with help of sulphuric acid, or 
acetic and nitric acids ; changed by warm sulphuric acid into sugar 
(Biitschli) or also by saliva and sulphuric acid. (8) Pyxinin, the cor- 
responding substance in Pyxinia, changed by acetic or nitric acid into 
an amorphous substance without iodine reaction. (9) Anti-enzym, a 
hypothetical substance which hinders digestion. (10) Morulin, the 
substance of the nuclear-morulite ; soluble in nitric acid, not in acetic, 
nor thoroughly in enzymes. (11) Paramorulin, the network in the 
nucleus, fixed by acetic and nitric acids, digestible, = Linin ? (12) 
Nuclein, in the nucleoli of Pyxinia , &c. (18) Nuclear-sap. (14) Cell- 
sap. And besides these, account must be taken of the granules which 
occur in regular rows, those of the anterior protomerite, of the deuto- 
merite, and of the epimerite, and finally the sarcocyte-fibrils and the rare 
vacuolar spaces. Frenzel has also endeavoured to prove the likelihood 
of the occurrence of a diastatic ferment. He compares the Gregarine to 
an absorbing intestinal cell, and believes the above analysis to be of 
interest in considering the processes of digestion and absorption in 
Metazoa. 
New Sporozoa.* — Dr. P. Mingazzini describes Gonobia colubri g. 
et sp. n., which occurred mixed with the spermatozoa in the vas deferens 
and testes of Zamenis viridiflavus. In the oviduct and ova of the female 
the coccidian appears to complete its life-cycle. The author gives other 
examples of Sporozoa associated with ova, e. g. in Lacerta. In the 
pyloric appendages of Sphyrsena vulgaris another new form, Cretya 
neapolitana g. et sp. n., was found by Dr. C. Crety; it exhibits an 
exceedingly distinct plasmic reticulum. 
Pulmonary Gregarinosis in Stillborn Child.| — Sig. A. Severi re- 
lates the case of a stillborn child in whom the lungs were extremely 
large and atelectatic. Sections showed that the pulmonary tissue was 
beset with cell-elements, partly singly, partly arranged in nests, and 
these the author took to be Gregarinae (Monocystidea) from their 
morphological and tinctorial characters. 
Coccidium Infection.^ — Of the Coccidia hitherto recognized, says 
Dr. L. Pfeiffer, some inhabit epithelial cells, some the blood. The best 
known example of the former is Coccidium oviforme Leuckart, the ovoid 
cysts of which are found in the intestine and liver of rabbits and of man. 
In the salamander dwells Karyophagus Salamandrse Steinhaus which is 
identical with C. proprium s. sphsericum described by Schneider. In 
the intestinal epithelium of the Myriopod Liihobius fortificatus is found 
Eimeria Schneideri. The micro-organisms infesting the intestinal 
canals are very pathogenic to their hosts, ninety per cent, of rabbits 
attacked perishing from diarrhoea and spasms. Blood infection by 
Coccidia has not been often detected, although Bordier and Smith have 
found some forms in cattle, and Texas fever appears to be due to
