starch, provided pepton be present. If ammonia he the only source of 
nitrogen in the medium, then the microbe has no fermentative power. 
Bacillus cyaneo-fluorescens.* * * § — Herr W. Zangemeister describes a 
bacillus found in coagulated milk on the surface of which were dark 
blue flakes. The pigment was of Berlin blue colour, and insoluble in 
water, alcohol, ether, and chloroform. The bacillus is oval in shape, 
short and thick, with flagella at both ends. It is very mobile, grows 
well at room temperature, does not liquefy gelatin, and the colonies on 
this medium are round and white. The medium becomes stained of a 
greenish-yellow colour and fluoresces briskly. The gelatin colonies 
smell strongly of trimethylamin. This organism combines the charac- 
ters of two species, viz. fluorescent and cyanogenus. The pigment is 
formed only when the reaction of the medium is acid. 
Bacteria of the Conjunctiva and Eyelid.f — The communication of 
Dr. C. Brandt on bacteria which have been detected on the eyelids and 
conjunctiva, has for its chief object certain measures for the repression 
or removal, by means of bandages and ointments, of the parasites. Of 
the therapeutic and longer portion of the author’s work, notice need not 
be taken ; and of the shorter and preliminary portion it need only be 
said that it is practically confined to an enumeration of the bacteria and 
fungi which have been found by different observers on the lid margins 
or on the conjunctiva. 
Pneumobacillus of Friedlander.J — M. L. Grimbert found, from a 
study of the fermentative products of the bacillus of Friedliinder, that 
these were ethyl-alcohol, acetic acid, lscvolactic acid, and succinic acid. 
While glucose, galactose, arabinose, mannite, and glycerin give lsevo- 
lactic acid only, saccharose, lactose, and maltose give both succinic acid 
and laevolactic acid, while dulcite, dextrin, and potato produce only suc- 
cinic acid. Acetic acid was met with in a state of purity in all the fer- 
mentations. Ethyl-alcohol was sometimes absent, as in the fermentation 
of arabinose and potato ; or traces only were found, as with glucose, 
saccharose, and maltose. With dextrin, it is mixed with a small quan- 
tity of the higher alcohols. With mannite, the ferment produces hevo- 
lactic acid, while dulcite gives only succinic acid. In consequence of 
his results differing from those obtained by Frankland, the author con- 
cludes that there are two Pneumobacilli Friedliinder, which, though 
morphologically alike, differ in their fermentative action, and suggests 
that the action on glycerin should be ascertained before a definite con- 
clusion is arrived at. 
Streptococcus and non-Diphtheritic Angina.§ — Prof. G. H. Lemoine 
examined 168 cases of angina, of which 112 were scarlatinal (74 pseudo- 
membranous, and 38 erythematous), the remaining 58 being distributed 
among measles, mumps, simple and membranous tonsillitis, and chronic 
tonsillitis (3 cases). The material used was obtained from the tonsils. 
The patient having washed out the mouth with sterilised water, the 
surface of the tonsil was swabbed with’ cotton wool,' and a portion of
