248 TYPHOID FEVER. MALTA FEVER 



in this asylum during August-December 1900. 

 Inoculations were begun on 6th September, by Dr 

 Cullinan, and by 30th November 511 persons were 

 inoculated. After careful criticism of all doubtful 

 cases, Professor Wright gives the following 

 figures : — 



Comparative Incidence of Typhoid Fever in Inoculated and Non- 

 Inoculated, calculated upon the average strength of the repre- 

 sentative groups during the period intervening between the 

 com?nence?nent of the inoculations and the termination of the 

 epidemic.

11. Deelfontein. The Lancet, 18th January 

 1902, contains a paper by Dr Washbourn and Dr 

 Andrew Elliot, on 262 cases of typhoid fever in the 

 Imperial Yeomanry Hospital at Deelfontein during 

 the year March 1900 to March 1901. (See Dr 

 Washbourns earlier letter, Brit, Med. Jour., 16th 

 June 1900.) They say: " In 211 of our cases, it 

 was definitely recorded whether the patient had 

 been inoculated or not : 186 of these cases had not 

 been inoculated, with 20 deaths, or a mortality of 

 10.7 per cent ; 25 had been inoculated with 4 deaths, 

 or a mortality of 16 per cent. The mortality was 

 thus higher among the inoculated than among the
