IX. Summary of Parasitological Investigations from Greenland. . 141 
Inoculations from two cases of hygromata in Bursa olecrani sinist. (into 
bouillon and into gelatine respectively) gave negative results. 
In two cases of periostitis acuta costæ with sequestrum-formation, 
staphylococci were detected in the pus with the aid of a microscope. 
It will thus be seen that I found staphylococci in furunculi, abscesses, in 
an adenophlegmon, a subcutaneous panaritium and in two cases of acute 
periostitis with necrosis of the costæ; while in all the carbuncles, in a 
phlegmonous process upon the hand and in two cases of diffuse phlegmon 
I found streptococci or diplococci. 
ll. Diseases of the Skin. 
In three cases of Eczema seborrhoicum capitis (Unna) in young 
Greenland children the microscopical investigation of the crusts, etc. demon- 
strated the presence of streptococci, diplococci and monococci which were 
stained by Gram’s method. In some of the streptococci-chains, from one of 
the young patients, the individuals were distinctly arranged in diplococci. 
Impetigo. Microscopical investigation of the contents of the entire 
uninjured vesicles and pustules in three cases of Impetigo in Greenland 
children showed mainly diplococci besides monococci and short chains 
(consisting of 3—4—5 individuals) which were stained by Gram’s method. In 
one of the three cases, cultivations were made from the vesicles, with the 
result that small, yellowish, roundish colonies were developed which did 
not liquefy gelatine. In puncture cultures in gelatine the bacteria grew out 
from the mouths of the punctures and spread upon the surface of the gelatine; 
in this the cocci differed from Streptococcus pyogenes. 
In а case of Ecthyma in a nine-years-old girl the microscopic investiga- 
tion of the contents of a pustule showed a few scattered cocci and short chains. 
Favus. In a case of wide-spread scurf (Favus) which had resulted in 
almost complete baldness in a young Greenland woman, on investigation of 
the brimstone-coloured crusts from the scalp, the fungus Achorion Schønleinii 
was found. 
In Herpes tonsurans (Tinea tricophytina) in Greenland cows 
“Tricophyton tonsurans” was demonstrated. 
In the Greenlanders, Scabies apparently can be produced both by 
Sarcoptes scabiei and by Psoroptes longirostris. I have found both these 
parasites in the inhabitants of Greenland; but judging from the clinical 
symptoms, etc., I must conclude that in the home-born inhabitants of Green- 
land itch is most frequently due to the presence of Sarcoptes scabiei.

Ш. Diseases of the Eye. 
Among the twenty-two cases of disease of the eye which were investigated, 
twelve apparently should be referred to the heading: Conjunctivitis, without the 
action of bacteria being able to be demonstrated. In the ten cases in which 
the bacteria which were found måy be presumed to have produced the 
Conjunctivitis, or at least to have been instrumental in increasing the affec- 
tion, I found in five cases pneumococci (Diplococcus pneumoniæ, WEICHSELBAUM) 
or varieties of pneumococci in the discharge. In five cases bacilli were demon- 
strated, most frequently coccobacilli, which were not stained by Gram's method.
