Calf Lymph Operations.
During the six months (Jan. 1st to June 30th) twelve
calves have been inoculated, nine Buffalo calves and three
English calves. Of these, one calf died of Rinderpest and one
did not take well, the rest gave apparently good lymph which has
been stored at-10°C till required.
A continuous supply of lymph has been kept up during
the period and 5782 tubes have been issued.
As an instance of the great value of cold storage of
lymph in a hot climate such as HongKong, it may be of interest
to record that tubes of a lymph made by me over three years ago
and kept in the Cold Store were issued this year at the hottest
season and were reported on as giving excellent results. It is
now quite practical to make lymph only at the most suitable
season 1.0. in the cold weather and still have a continuous supply
of lymph all through the year.
The addition of clove oil to lymph as a purifying agent
as recommended by Dr. Blaxall (appendix C. Report of Medical
Officer, Local Govt. Board 1911 12) is also being tried and
the results will be reported when sufficient experience has been
required.
