Lymph was stored and prepared for experimental purposes in the following
forms :—
(1) Simple lymph, capillary stored.
(2) Simple lymph, capillary stored, sealed at either end with
glycerine.
(3) Lymph pulp, glycerised.
(4) Lymph pulp, lanolised.
The first method was successful when used shortly after preparation.
The second and third methods were not successful.
The fourth method was highly successful.
The vaccinia disease in the calves operated on in the hills runs a regular and
typical course, and in some is most active and attended with secondary vesicles.
But in all it is somewhat retarded on account of the great coldness of the winter,
so that about twelve hours longer than in the plains are required for maturation.
The maintenance of a sufficient supply of calves is the chief difficulty in con-
nection with the working of the depôt at Darjeeling, but this it is hoped, as
time advances, will be overcome. On the whole, I have every reason to be
satisfied with the starting of the depôt at Darjeeling, and am quite sure that
as long as it is under able management, like that of Dr. Waddell, it will be a
success and a source of dependable lymph-supply. With this depôt in the hills
and the central depôt in Calcutta, the Vaccination Department is now in a posi-
tion to dispense with lymph obtained from the human subject, and to supply
the whole of Bengal with calf lymph. It remains for Civil Surgeons under
the reorganization scheme of vaccination to indent on the Animal Vaccination
Depôt nearest them for their requirements, and to encourage the use of bovine
lymph, which they should have no difficulty in doing, as it is of itself fast
growing in popularity.
Scarifier method of vaccination.
19. In advocating the use of lanoline as a preservative of vaccine
lymph, Dr. King of the Madras Sanitary Depart-
ment urged the necessity of substituting an instru-
ment called the scarifier for the ordinary lancet, and Dr. Waddell considers this
instrument to be all but indispensable to the successful use of lanoline lymph,
but my experience and that of several medical officers with whom I have
discussed the matter is that as satisfactory results can be obtained with
the lancet, and this is proved by the results of the experimental operations
shown in the appendix to this report, the majority of which were performed
with the ordinary lancet. As, however, the scarifier is a much cheaper instru-
ment, costing 6 annas only, while a lancet costs Rs. 2, and as its use is so
strongly advocated in preference to the lancet by Drs. King and Waddell, who
have made the subject a special study, I obtained the permission of Govern-
ment to Dr. Waddell's deputation to teach the officers of the Vaccination
Department its use. As the deputation extended only from the middle of
January to the end of March 1892, and as Dr. Waddell at the same time retained
charge of the routine office work of his circle, and also of the newly-started
Animal Vaccination Depôt at Darjeeling, this limitation of time rendered it
physically impossible for him to visit all the districts of Bengal. But starting
on the 26th January 1892, he visited the following 23 districts :—
