SUMMARY OF CURRENT RESEARCHES RELATING- TO 
rounded ends. Other bacilli are longer, 6-8 /x, and these have one swollen 
end like the clubs of Actinomyces. Indeed the general arrangement is 
strikingly like that of Actinomyces , though no mycele was made out. 
iEtiology of Leukhgemia.* — Prof. M. Lowit communicates the more 
important results of his observations on leukliaemic blood. In myelaemia 
there is a leucocytic haem-amoeba which he proposes to call Hsem - 
amoeba leuklisemise magna. Multiplication takes place in the blood by 
means of spores, as in acystosporous sporozoa. In blood-forming organs 
spores having the characters of resting spores can be demonstrated ; but 
whether there is a proliferation through chromatozoits (crescents) is 
not yet determined. 
In lymphasmia the parasites are rare in the peripheral blood. In 
the blood-forming organs another parasite, Usemamceba leuklisemise vivax , 
is found both in the cytoplasm and in the nucleoplasm. In cases of 
mixed infection both parasites are to be found. To certain animals the 
leucocytic infection can be transferred from man and also from animal 
to animal. 
Morphology of Glanders Bacillus. j — Dr. H. Marx has observed in 
cultures of glanders, forms with bulbous swellings, branching forms, 
buds and filaments of varying shape and size. The preparations were 
taken from potato, carrot, and gelatin cultures. The author considers 
that these branchings indicate the relationship of glanders bacillus to 
Actinomyces. 
Bacterium from Diabetic Urine.J — Herr G. Marpmann has detected 
the constant presence of a bacillus in the urine of persons suffering from 
alimentary diabetes. The bacillus is from 1*5-2 fx long and 0*2-0 *3 /x 
broad. Attempts to cultivate on agar at blood-heat failed. The bacillus 
was not found in cases of traumatic or nervous diabetes. 
iEtiology of Epidemic Conjunctivitis.§ — Dr. L. Kamenhas had an 
opportunity of observing an epidemic of acute conjunctivitis which 
attacked the garrison at Czernowitz. Pie is of opinion that it was 
caused by the Koch- Weeks bacillus. Pure cultures were most easily 
obtained on Pfeiffer’s blood-agar. Morphologically and biologically, 
the bacillus appears to belong to the influenza group. It is extremely 
perishable and but little adapted to a saprophytic existence, as is shown 
by the difficulty of obtaining subcultures and their rapid decay on 
artificial media. It seems to be little, if at all, pathogenic to animals. 
Bacillus from Relapsing Fever Blood. || — Dr. S. M. Afanassiew has 
found in the blood of relapsing fever patients (17) a bacillus as well as 
the spirillum. The bacilli were always found during the fever. In the 
early stage (first day) they are small (1-1*5 /x X 0*3 /x) with rounded 
ends; later they became longer, 5—6 /x, and sometimes filaments 10-14 /x 
were observed. In every field 3-30 individuals were present, and it 
was noticed that the spirochmtm, as well as the bacilli, were invested 
with a non-staining sheath. Cultivations were obtained in bouillon,
