REMARKS.
13
Death-rate 0.58
per cent.
In 31 outbreaks of rinderpest from the four districts of Assam, 3,905 cattle
were injected with " serum alone " of which 23 died with a mortality of 0.58
per cent.
From the above returns, it is difficult to determine the cause of the large
mortality previous to injection with serum, as we are not in possession of
facts with regard to the respective breed of bovines operated upon. One thing,
however, is clear, namely, that the great majority of animals were highly
susceptible to rinderpest and that the injection of serum was not carried out
until sometime after outbreak commenced.

REMARKS.

Municipal
cattle.
Death-rate 0.91
per cent.
It is evident from the above return that, of 6,335 cattle injected with
" serum alone " in 118 outbreaks, 58 or 0.91 per cent. succumbed to the
disease, and that a large proportion of bovines were susceptible to rinderpest.
59. Foreign countries.—The Veterinary Surgeon, Singapore, in his letter
dated 25th April 1906, to the address of the Imperial Bacteriologist states :—
" The serum has been of the greatest use in cutting short what promised
to become a very serious outbreak, and I have applied to my Government to
provide this Department with a stock of 400 doses to keep on hand in case of
emergency."
60. The total number of outbreaks in India and Burma dealt with during
the year under report was 910, in which 124,015 animals were injected by
the " serum alone " method against 56,483 during 1904-1905. The mortality
was 0.31 per cent. amongst the injected animals as compared with 0.46 per
cent. during the last year.
In estimating the good work accomplished during the year with anti-
rinderpest serum, the number of animals injected is not of so much importance
as the number of different outbreaks of the disease successfully dealt with.
Before the serum treatment was introduced, some years ago, the disease
was observed to spread across the country like a wave of the sea, leaving the
