CURATIVE TREATMENT OF SURRA IN EQUINES               99

13 mules treated ; 10 cured, 3 developed paralysis during treatment and were
destroyed. Bombay — 1 charger cured. To sum up, the total number of animals
in the four outbreaks mentioned above was 76, out of which 68 (or 89.5 per cent.)
were cured, and, according to the Administration Report of the Army Veterinary
Services in India for 1928-29 (p. 7), none of the animals declared as cured in the
Mona outbreak relapsed during a post-treatment observation period of about one
year. In the same Report, mention is made of 45 further cases of equine surra,
and of these, " 18 were destroyed as the condition of the animals did not warrant
treatment, one died under treatment and 26 [96.3 per cent.] were cured". In the
Report for 1929-30 (p. 8), mention is made of 40 cases of equine surra — " 39 in
the Burma Independent District amongst mules and 1 amongst horses in Southern
Command". Of these " 31 were treated with Naganol by the combined method",
and out of these ''24 [77.4 per cent.] were cured, 5 died and 2 were destroyed. In
the remaining 9 cases, the condition and age of the animals were such that treat-
ment was not warranted".

The recent Reports of the Civil Veterinary Department of Bihar and Orissa
mention occasional cases of equine surra having been treated with Naganol in that
province, and, so far as can be gathered, the combined method of injection was
adopted in all the cases treated. The following extracts are of interest as being
illustrative of the extent to which drug intervention is likely to prove useful under
the ordinary field conditions in India :—

Report for 1927-28.—8 cases of surra were reported. Out of these, 5 died,
1 was destroyed and 2 were cured with Naganol.

Report for 1928-29.—5 cases were reported. Of these, 3 died and 2 were cured.
"The Mounted Military Police horses, while on their way back from Jamshedpur,
were successfully treated by Naganol injection."

Report for 1929-30.—Four cases of surra were reported. I died before treatment
and the others were cured with Naganol.

Report for 1930-31.—Seven cases of surra were reported. Four died before treat-
ment ; one—an advanced case—died soon after treatment, and the remaining 2 were
cured with Naganol.

IV.—THE RELATIVE EFFICACY OF THE INTRAVENOUS AND THE INTRAVENOUS-
                      INTRATHECAL METHOD OF TREATMENT.

From what has been stated in the foregoing sections, there would appear to be
on record hardly any comparable figures to allow of any definite conclusions being
drawn as to the relative advantages of the intravenous and the intravenous-intra-
thecal method of using " Bayer 205 " in the treatment of natural cases of equine
