very satisfactory. As tested at the depôt and in Shillong, results were also satisfactory. Fifty-three
children were vaccinated in the depôt or by the depôt authorities, all successful. Experiments
were made with lymph kept in stock at various times, and found successful and just as satisfactory
47, 59, 97, and 109 days after loading as when just loaded.

The Political Agent, Manipur, reports he has received his supply regularly, and the quality has
been good.

Revd. Clark, the Missionary at Mokokchang, reports very satisfactory results: of 289 vaccina-
tions, quite 280 were successful. He says the development was very fine in most cases.

Dr. Gillespie, the planters' doctor at Addabari, Darrang, says the fortnightly supply has
been of most excellent quality, giving the most satisfactory results. He afterwards got a weekly
supply.

Surgeon-Major Macnamara stated to me verbally he had seldom had a failure, and the vaccina-
tors averaged well over 90 per cent. successful, and this was in Sylhet, to which district 2,000 tubes
were sent weekly.

Surgeon-Captain Dobson of Dhubri also informed me that the supply was of very good
quality.

Lanoline lymph

17. No experiments were made with lanoline during the season, as it required all the time of
the depôt establishment to carry on the routine work of loading
tubes with glycerine lymph. A fresh supply of lanoline has been
received from England from Ferris & Co., and already I have started manufacturing lanoline
lymph, and will send a report on it and the comparative results compared with glycerine tube lymph
in October, as experiments can be fully carried out during the non-working season. As glycerine
lymph in tubes has proved so successful, it would be a mistake at present to change to lanoline,
unless it can be proved more successful, easier of manufacture, keeps better, and as practicable for
general use.

General remarks.

18. One of the drawbacks to this depôt was the want of a proper water-supply, as water had
to be brought from the foot of the hill some little way off, and this
was a hardship, as the quantity of water required for flushing and
cleaning out the two calves' sheds and the operation room was considerable. The Government of
Assam has sanctioned Rs. 400 to build a masonry tank and supply water to the depôt for the ensuing
year, which will be a great improvement.

19.  The Hospital Assistant in charge, second-grade Hospital-Assistant Pratab Chandra Bose,
has worked zealously, and I hope the Government of Assam will see its way to allowing the extra
grant proposed by the Deputy Surgeon General, as this special work requires a skilful and zealous
worker, and can only be a success if he is careful and attentive to his duties.

20.  The work has increased very much this year, as may be seen from the increase in the
number of tubes distributed, i.e.,—

which is almost double what it was in the previous year.
