Miscellaneous Examinations.—Examinations were also conducted
during 1905 in the Borough Laboraiory on the following :
1. Urines—
(1) Chemical examinations (6).
(2) Bacteriological
For detection of B. Typhosus in cases convalescent of
Enteric Fever. Thirty specimens, of which eight
gave positive results.
2. Blood—
(t) Blood from three patients ; the examination of their blood
was of great assistance in diagnosis and prognosis.
The one led to an operation for an abscess, and recovery,
and the second was one of Splenic AnEemia followed
rapidly by death. A third case shewed Lencocytosis
after Pulmonary Tuberculosis, but as death
occurred from a subsequent complication, the
examination was not of great help.
(2) Blood and tissues from a supposed case of Anthrax in a
bullock gave negative results. The bullock had died
from advanced Tuberculosis of the lungs and internal
organs.
(3) Several specimens of blood were also examined of a case
of Malta Fever, but this gave no definife results.
(4) Further investigations were also conducted on the blood
of severe and malignant cases of Scarlet Fever.
3. Pus —
(1) Three for gono-coccus (all j ositive).
4. IVater—
(1) The experiments on the softening of the Croydon Water
Supply were continued during the earlier part of the
year. Altogether 20 samples of water were analysed.
In artificially polluted water it was shown that the bacteria
could be diminished in the water (by softening and
sedimentation) by 92 to 96 per cent.
5. Ringworm—
Thirty-six specimens of hair were examined microscopically ;
of these, 26 shewed Ringworm spores (all small spored—
M. Audouini) and 10 shewed 110 spores.
