1. The consumption of lucerne hay and water by merino sheep has been recorded in two separate but identically concluded experiments under the following conditions: (i) Both food and water given ad lib. (ii) Water restricted to 2 litres, food ad lib. (iii) Food restricted to 0.6 Kg. water ad lib. 2. A highly significant positive correlation was found between the amounts of hay and water consumed when both were offered ad lib. 3. A highly significant positive correlation was also found between the amount of water consumed and the maximum atmospheric temperature for the day. This coefficient was enhanced by feeding a fixed amount of hay in the first experiment but not in the second. 4 . No direct correlation could be shown between the hay consumption and atmospheric temperature when water supply was unrestricted. In the first experiment a highly significant negative correlation was found between these two factors when a fixed amount of water was given, but this could not be confirmed in the second experiment. 5. Urine was collected from representative animals from each group. It was found that the animals on a restricted water supply maintained a low water to food ratio by passing small amounts of highly concentrated urine (urea up to 8.1 gm. per 100 c.c.). Marked variations were found between individual sheep receiving both hay and water ad lib. in respect of volume and concentration of urine.

An analysis has been made of the stomach contents of cod, chiefly of the 0-group, some also of the I-II groups from deep water in some fjords in North Norway during the years 1946-1949. The cod were all caught in the period August-November, except for single samples from March and May. The cod were found to feed almost exclusively on Euphausiacea, mainly Thysanoëssa inermis. In some places the Mysidacea were also important, chiefly Erythrops serrata and Michteimysis mixta. More locally other food species may be of importance, such as Decapoda (Pandalus borealis), Amphipoda (Rachotropis macropus and Halirages fulvocinctus, Isopoda (Eurycope cornuta), Copepoda (Calanus finmarchicus, Undinopsis similis, Harpacticoida), fish (Lumpenus maculatus and others). Decapoda and fish play a greater part as food of cod of the I-II groups than of the 0-group.
