Some years ago gas was laid on in the Sisters’ rooms in Guy’s Hospital. In the other Hospitals there is an allowance of candle to each Sister. The disadvantages of gas are its alleged unhealthiness and its certainly being disagreeable to some eyes. Its advantage is its cheapness. Liberty to buy a candle and not use the gas is allowed at Guy’s. As it will be a very important thing to conduct the Nursing Service as economically as possible, and as there must not be any wretched false economy as to essential matters, which in the end always proves waste, it will be well to save as much as can be in matters not essential. It would be worth while to ascertain the average amount of saving which the substitution of gas for an allowance of candle has effected at Guy’s. Gas is used in the wards of St. Bartholomew’s, St. Thomas’s, and Guy’s, day and night. It appears, when ventilation is properly attended to, to answer well, and to do no harm. At night the gas is lowered so as to leave the ward just light enough to see all that is done in it: if bleeding, &c. occurs, it can in an instant be raised, and the ward lighted up. London Hospital burns gas in the evening, and throughout the passages at night; but when the night watch begins at nine, the wards are dark, except the Nurse’s candle. A spare candle, un-lighted, is always at hand. It is very important for the order of a ward that the attendant in charge, and also any inspector suddenly entering, should see at once all that is going on in the ward. Where there are dangerous cases, this is of great moment; and where there are not, it is equally necessary for the police of the ward. A candle or a rushlight give insufficient light. Properly lowered, gas at night does not disturb the patients. After a night or two, those who are accustomed to sleep in the dark get used to it. If the Nurse sleeps adjoining the ward, there _must_ be sufficient light in the ward at night. If the gas-fittings are properly tight and if every gas-burner has a ventilator, so that the products of combustion are effectually conveyed away, for each gas-jet consumes as much air as eleven men, it would be greatly preferable that there should be a low gas light in the wards at night. [Sidenote: II.--1. Should it be necessary to serve one Pavilion with one Nurse means by which this could be effected.] II.--1. Suppose the Lariboisière plan retained, as proposed at Aldershot, for a Military Hospital, with wards of twenty-four beds each--then, with fear and trembling, but with the firm conviction that it is better for human nature, most of all, for nursing human nature, to have somewhat too much than a great deal too little to do, I respectfully recommend that one Nurse serve the three wards of each Pavilion.
