31 I would suggest that a copy of this report be circulated to the Veterinary Inspectors and Officers, so that they will know the numbers of cases of various diseases diagnosed and the work which has been done, and in the hope that it may stimulate interest in the collection of pathological material for the laboratory, and also in veterinary survey work.

In conclusion, I wish to acknowledge the assistance obtained from Major R. G. Archibald, D.S.O., Captain N. T. Whitehead, M. C. and Mr. A. Marshall of the Wellcome Tropical Research Laboratories.

I have the honour to be, Sir, Your obedient servant, (Sd.) R. H. KNOWLES, Bimbashi, Veterinary Bacteriologist, Sudan Government.
