87 . the Lipins of the Earthworm

THE majority of aniimal fats examined in detail have been from vertebrates. In connexion with the feeding experiments described in the preceding paper, a knowledge of the composition of the mixed fatty acids of earthworms was desirable and a large quantity of worms was collected over a considerable period and kept in cold storage until sufficient was available for fatty acid analyses. In view of the unexpectedly complex mixture of acids found, a second, larger quantity of worms was collected and a second analysis carried out, which confirmed in every respect the first conclusions.
