inoculation, one after inoculation and two did not take well so that the lymph was discarded. All of the 14 calves from which lymph was taken were subsequently slaughtered and declared healthy by the Colonial Veterinary Surgeon. About 1,200 grammes of lymph are now in stock, sufficient for about 18,000 people, presuming it to be all potent.*
It is reasonable to expect that by means of this cold storage a plentiful supply of potent and more or less (extraneous) germ-free lymph can be kept ready for use at any time and quite irrespective of the hot summers which we experience here.
A sample of lanolinated calf lymph was received from the Lister Institute for testing in July last. Carefully following the special instructions sent with the lymph, a calf was vaccinated—half with the lanolinated lymph and half with our own stock lymph. Our stock lymph took well, whereas the Lister Institute lanolinated lymph did not take satisfactorily. This result is similar to that obtained with a similar sample sent out for testing by the Acting Government Bacteriologist, Fleet-Surgeon Shaw, R.N., (see report for 1909 Annexe L).
Seven thousand nine hundred and ninety-seven (7,997) tubes of lymph have been issued during the year compared with 9,591 in the year 1909. Of the 7,997 tubes issued, reports have been received on some 1,092 cases only. This is unsatisfactory, and it is proposed to reorganize the method of reporting next year so as to get a larger number of cases reported on if possible.
Table I shows the results derived from the reports on the 1,092 cases. The obvious objection is that these figures are too small to be safely accepted.
