§ Mr. H. Morrison
The published return for 1939 shows that the total number of experiments performed in that year was 954,691, of which, as pointed out on page 5 of the return, a large number were almost wholly simple inoculations and similar proceedings performed either on behalf of official bodies with a view to the preservation of the public health or1742W directly for the diagnosis and treatment of disease. The figures for the next three years were:
1940 … … … 889,677 1941 … … … 764,013 1942 … … … 932,448
I regret the figures for 1943 are not yet available.
