1. Individually caged wild house-mice (Mus musculus L.) were fed 0·025% warfarin in a pinhead oatmeal/oil/sugar base. In all, 345 mice were tested for a fixed period ranging between 4 and 28 days.

2. There was considerable variation in the susceptibility of individual mice. The lowest effective dosage was 26·1 mg./kg. of body weight in 4 days and the highest dosage survived was 1067·2 mg./kg. eaten over 21 days.

3. The time required to obtain a 100% kill of house-mouse populations with 0·025% warfarin under field conditions is discussed.
