IX. Summary of Parasitological Investigations from Greenland. 143 
gave the impression of being merely occasional visitors. The cocci were 
always predominant in the microscopical illustrations. 
In the two cases in which cultivations were made from the Aphthæ- 
patches, the cocci were proved to be able to grow in the usual nutrient 
media and to liquefy gelatine, forming large cup-like hollows upon the sur- 
face of the gelatine, but the liquefaction took place slowly and imperfectly 
(as was the case with the strepto-diplococci which were cultivated as men- 
tioned above, from the panaritium upon the left hand). 
On microscopic examination of the white,, soft, shiny layer which 
covered the tooth-neck of two extracted teeth, bacteria were found which 
agreed with the common bacteria of the mouth described from other 
countries, viz. Leptothrix innominata, Bacillus buccalis maximus, Spirillum 
sputigenum, etc. 
V. Catarrhus intestinalis acutus. 
In the six cases of Catarrhus intest. acut. in which cultivations were 
made from the dejecta, the bacteria present proved to be Bact. coli com- 
mune; in two cases Proteus vulgaris, Hauser, was also found, but only 
few in number, and possibly due to contamination outside the organism. 
In eight cases of acute catarrh of the intestines, when only microscopic 
examination of the evacuation was made (without simultaneous inoculation 
and cultivation) bacteria were seen which were exactly similar to Bact. coli 
(coccobacilli — long rods with rounded ends, etc.) and which usually also 
could not be stained by Gram's method. 
Cultivations from normal, solid, definitely-shaped fæces from a 56 years 
old, married ‚Greenlander gave pure cultures of Bact. coli commune (the 
transparent. variety). It was stained (in the шиезНпа! contents, not in the 
cultivations) by Gram’s method, but did not differ in any point from the 
specimens of the bacillus found during the catarrh of the intestines. 
Cultivations from the intestinal contents of a recently shot ptarmigan 
(Lagopus mutus) showed Coli-like coccobacilli which were not stained by 
Gram’s method, but liquefied gelatine. 
VI. Diseases of the Urinary and Sexual Organs. 
A. Hæmaturia, Bacteriuria, etc. 
In seven patients with Hæmaturia, microscopic examinations of the 
urine were made; in six of these seven cases cultivations were also made 
from urine which was taken under sterile conditions. Bacteria were present 
in the urine of five of these patients; only in two cases the urine was sterile. 
In the five cases in which bacteria occurred in the urine they always proved 
to be Bact. coli commune. 
The Greenland Bact. coli commune (Bacillus coli) does not appear to 
differ. in any special points from the intestine and urine bacillus described 
from other countries. In gelatine, plate- and “rolled” cultivations it occurred 
under the two usual forms: the transparent and the opaque variety, united 
by a series of transitional forms. The bacterium proved to be very poly- 
morphous, it moved rapidly, did not liquefy gelatine and was not (in the
