During the finishing processes of cloth-weaving at spinning factories, the workers perform their labour almost always in a standing posture. However, the author's examination of these worker's urine has revealed the absence of any diseased symptoms in it. The author's subsequent examination of the pH, Donaggio-Sato Reaction and Takeya-Kawata Reaction, shown by the urine, has produced the following results. Generally speaking, during the first half of the working hours, the fatigue of the workers gradually increases, while in the second half their fatigue decreases by degrees. At the commencement of their labour, the workers of the later shift show greater fatigue than those of the earlier shift. Probably because the former, before leaving for the factory, are allowed to spend more time at home than the latter. However, as the shift, both earlier and later, go on with their labour, they get more and more accustomed to it, hence less and less fatigue results. To sum up, labour required by the finishing processes of weaving cloth is one below medium degree and the fatigue it causes is one that is completely relieved in the course of the day.
