SUPPURA TION.                          205

Bouchard, Boisnet, and Bordas also found micro-organ-
isms in the blood and saliva.

Netter, I^averan, Catrin, Mecray, and Walsh have all
studied cases and isolated a diplococcus thought to be
specific. The organism is described as occurring in pairs
and in fours, sometimes in zooglea. It grows slowly in the
ordinary media, clouding bouillin in twenty-four hours,
and appearing on gelatin after forty-eight hours as small
white punctiform colonies which develop very slowly
and liquefy some considerable time after coalescence.
It grows on potato, and has a whitish appearance not
easy to detect. Laveran and Catrin found the organism
in 67 out of 72 cases examined. In their method a
few drops of exudate are withdrawn from the inflamed
gland with a hypodermic needle, some of the negative
results being due to the fact that the needle withdrew no
exudate. The blood gave pure cultures in 10 out of 15

Mecray and Walsh report that by disinfecting the
mouths of patients, suffering from mumps, with a satu-
rated boric acid solution, and cleansing Stensen's duct,
by careful massage expressing its secretion, and then
allowing a piece of cotton saturated with a boric acid
solution to remain for five minutes between the orifice of
the duct and the jaw, they were able to secure from the
interior of the duct upon a bougie of sterile catgut a
micrococcus identical with that Laveran had found. Of
tubes inoculated with the contents of Stensen's duct 6
gave a mixed growth. All, however, showed the diplo-
coccus. Out of 8 carefully made blood examinations, 3
gave pure cultures of the coccus and 3 mixed cultures; 2
were negative.

From Stensen's duct in healthy children they obtained
the various oral bacteria, but not the diplococcus found
in the cases of mumps. The experimenters do not think
it possible that this diplococcus is the Staphylococcus
epidermidis albus, as its growth is slower and the lique-
faction of gelatin is accomplished only after a longer
