exertion such as digging or rpowing a rough lawn with an old lawn-mower.The abdominal wall felt icy to the touch, and aftersuch exertion I would have an acute attack as described.It could not be put down to icy water as we had no refrigerator and usually the water remained tepid after boiling.Stools were negative.Apart from these acute attacks I normally had three or four loose stools daily during the hot weather.I eventually found that a " belly pad " consisting of about a square foot of woollen vest, lined on the inside with an old piece of " lock-knit " cotton material, tied round the neck and waist, was almost specific.The Chinese (Hakka) people dress their small children in a "belly pad " in the hot weather.-Iam, etc., Leyburm, Yorks.
