?43 by Major Gibbs and published in my report on Mhow. The amount of water passing through the sub-soil under the barracks and mounting by capillary attraction up into the solid plinths is a matter that in my opinion most seriously affects the health of the soldiers. As a rule barracks are not overcrowded, but sometimes owing to military exigencies overcrowding does take place; but this subject at all time engages the most careful and immediate notice of medical officers in charge of troops. The ventilation of the barracks in many stations is, during the monsoon, ex- cessive. If the doors are kept open, the men sleep in a draught and are liable to get a chill; if the doors are shut, they breathe the emanations from their lungs and bodies. What is required is that, fresh air should be admitted about half way up the wall, and such would be provided by the adoption of the door and window recommended by the Army Sanitary Commission and by Mr. Lumsdaine. The wastage water from the non-commissioned officers' rooms in barracks as a general rule is received into iron receptacles which either stand on the surface of the ground or are let down into a chunamed pit. Too often, either from the spout leading from the bath-room not being immediately over the centre of this receptacle or from the wind blowing the stream away, the water does not fall into it, but into the pit in which it stands. This wastage water is generally removed from the receptacles by puckauli bhisties by means of a dholl or tinpot, but a little always remains behind, and sometimes a not inconsiderable quantity. I have heard complaints that a smell from these receptacles sometimes finds its way into the rooms. The wastage water from the wash-houses, as at Nasirabad, is utilized in their immediate vicinity over gardens-a very dangerous proceeding with such a previous history as the sub- soil in the Infantry Lines at that station has. In other stations it is removed by puckauli bhisties and is either utilized for watering trees or is discharged into a nála. Dry earth is used in all latrines attached to barracks and hospitals, and the greatest care is taken throughout the Presidency to keep these places clean; but I cannot help regarding the standard latrines as a disease cause. Many are insufficiently ventilated, such as the left flank latrine at Ahmednagar, the Artillery latrine at Karáchi, the Artillery latrine at Nasirabad, the heavy battery latrine at Mhow, and others. I think the iron pans in use are more than probable the nidus of disease. These pans are dammered inside and out and they present inequalities of surface which, in spite of every care on the part of the sweeper, it is simply im- possible to keep perfectly clean, and they retain particles of filth which cannot be removed. The same remark applies also to the iron urinal tubs, no amount of ordinary cleaning can remove the salts deposited on them. The use of dry earth by the men also is not habitual. Some do throw a scoopful of earth into the pan after using, but very many do not. On in- spection morning it was generally found that dry earth had been deposited in each pan, but very frequently a sweeper would be seen hiding himself from observation. On visiting the latrines at odd times without notice the use of dry earth by the men was found in some stations to be exceptionable. The greatest attention in this respect was observed at Belgaum in the regimental latrines of the Royal Irish Fusiliers where the Quarter Master, Captain Watkins, is very particular in seeing that they are kept as clean as it is possible to keep them. In each latrine the following notice is pasted up:- "The soldiers of the battalion are directed never to leave a latrine without throwing a scoopful of dry earth into the privy pan. The application of the dry earth must be imme- diate, and the Commanding Officer desires to impress upon the men the necessity for a strict observance of this valuable sanitary precaution. He hopes that it will be unnecessary for him to place sentries on the latrines to enforce this order." The night-soil and urine are removed from the latrines and urinals in closed iron tubs which are kept in a passage behind these privies. These, too, it is im- possible to keep thoroughly clean, and they are not inspected as often as the privy pans. In my opinion they are a source of great danger and very possibly the nidus of enteric fever. B 357\?\
