DYSENTERIES.

It is to be regretted that no reduction in the incidence of these diseases can be recorded th s year, but at the same time it should be noted that the figures for the last three years show no marked increase and are specially consistent with regard to the bacillary type, to which the European population are more prone.

Of the total cases of both varieties notified, 23 deaths were presumed to have been due to dysentery or a case mortality of 7%.

With regard to bacillary dysentery among Europeans, a circular is being printed and issued giving advice on the protection of foodstuffs in kitchens, pantries and ice-chests and recommending a yearly examination of all servants. Also a trial is being made with disinfectant in each conservancy bucket, and greater attention is being paid to inspection of servants latrines which are thought to be a source of danger. Constant inspection of the stables, kitchens and outbuildings of all European houses, by a British sanitary inspector and immediate remedying of all nuisances in and around these houses, offer the best of hope of reducing the incidence of dysentery in Khartoum.

The following tables show the incidence of each variety by nationalities, sexes, age periods and the types of organism isolated in cases of bacillary dys¬ entery.
