14.—Spring called “Niegawa no yu.” (Destroyed). The following diseases were treated there.

Spring in the Nakasawa tea-house.

(This spring is not cited in the above work. It has a taste strongly tainted with alum, and contains sulphur and sulphate of copper. The inhabitants use it but little on account of its temperature which they find was 38° to 42°). Europeans suffering from slight complaints seem to derive benefit from it. Constant use of it seems to provoke irritation of the skin especially in the folds. It stimulates the functions of the kidneys. The following rules of Japanese hygiene are applicable.

‘On arriving at Kusatsu after a long journey and fatigued, it is well to repose for some days before commencing the treatment. The baths must not be resorted to in excess at first. During the first three days of treatment not more than three a day should be taken. After five or six days one may advance to five or six baths but never more than this. In general rather than decrease the daily number of baths it is better to intermit a day if necessary. The ordinary duration of the cure is three weeks, and for more serious cases from seven to ten weeks. For the gravest cases from 100 to 150 days. It is well to repeat the treatment the next year at the same season, in order that the germs of the disease may be uprooted. The number of baths should be limited, and their effect is diminished if this rule be neglected. During the first six or seven days, simple bathing should be resorted to, after this period the action of the douche may be submitted to. It is most dangerous to take this too early.
