GREY SEAL MILK FAT 193 near future an opportunity may be afforded of studyingthe blubber and milkfats of a seal at various stages during lactation, and also the blubber fat of the calf.SUMMARY 1. Grey (Atlantic) seal (Halichoerus grypu8) milk resembles whale milk in that its fat content is of the order of ten times that found in the milks of land animals.2. The composition of seal milk fat has been investigated: it contains only those acids which occur in its blubber fat.3. Qualitatively grey seal milk fat resembles that of the blubber oil of the same and of a number of other species, notable differences, however, occurring in the proportions of palmitic and un- saturated acids.4. Grey seal milk fat is relatively more saturated than that of the blubber oil in contradistinction to that of the blue whale, for which the reverse holds true.
