tactics are needed in going about, but in the frequently troubled water of Dublin Bay these matters are noteworthy when we remember that she is 60 feet long, has a beam of 12 ft. 6 in., and draws only 3 ft. 6 in. of water. [Illustration: Storm without, calm within.] [Illustration: Kingstown, Dublin Bay.] _Report of the Hon. Medical Officer_ In one of the steamers of which I had medical charge it was a common saying that all that was medicinally required by the crew and passengers was a weekly dose of 'one pint of sulphur wash and 2 oz. bilge nails,' and that teeth might be drawn by the 'key of the kelson.' No such drastic treatment should be required on a yachting cruise, but a few medicines and surgical appliances should always be on board, and the sanitary condition of the boat should be rigorously and minutely inspected, not only before starting, but daily during the cruise, be it long or short. To begin with, before stores or passengers come aboard I have the carpet or other covering taken up and some of the flooring lifted along the entire length of the boat, and I carefully see that no fragments of food, animal or vegetable, have accidentally got about the ballast, that no pieces of paper, however small, nor sawdust, nor shavings, nor 'matter out of its proper place' of any kind whatever, is left below the flooring. I personally see that the limbers are cleared, and that a copious flush of water redolent of calcium chloride or 'Sanitas' is poured in forward and pumped out of the well aft. Next, I inspect the sail lockers, and if there be any musty smell, I have the sails, &c., removed on deck and hung up to thoroughly dry; in the meantime the locker beams and ceiling are washed over with a solution of chloride of lime and thoroughly aired. The steward's store lockers and cooking utensils are carefully examined, a solution of potassic permanganate being freely used; the mattresses are turned over and searched for the slightest mouldiness, and, if any be detected, are sent ashore to be taken asunder and stoved; the lockers under the berths are aired, and the Indian matting with which the bunks are lined taken down and examined, and, should there be any mustiness, which will surely be the case if it has not been kept dry, I condemn it and get fresh--fortunately it is a cheap material. The w.c.'s are of the underline type and consequently require rigorous examination, as that kind is subject to leakage, and they should always be provided with simple means for tightening up the joints, and so devised that all the strains due to pumping, &c., are self-contained. There should also be an automatic supply of a strong solution of permanganate of potash every time the w.c. pump is used. Besides this, however, I always make the boy pour in a pint of strong permanganate solution night and morning, and with a good air-draught, secured by having the door made so that there are several inches above and below between it and its
