Note 61 — PART II. PREGNANCY.

The hot-water bag, or bottle as it is sometimes called, is composed of vulcanized india-rubber, and is made purposely to hold very hot water. The bag ought not to be more than half filled with water, as it will then better adapt itself to the shape of the bowels. The water must be hot, but not boiling hot; if it should be very hot, the bag ought to be wrapped in flannel.
