Bioelectric Characters of Amphibian Ganglia.

A description of the action potentials obtained from the cervical ganglia of Buffo marinus (Fijian toad) and the use of the ganglia to show the mode of action of such drugs as curare, prostigmine and acetyl-choline, with particular reference to the nature of synaptic transmission.

Bioelectric Recording and Measuring Technique.

The occurrence and significance of bioelectric potentials was discussed under the headings of (a) potentials produced by organs, (b) potentials of the nervous system. Methods of measuring or recording these potentials and outlines of apparatus required were described under the headings (1) action potentials of muscle, (2) action potentials of nerve tissue, (3) steady potentials.

A Survey of Fishery Research Progress in New Zealand.

By A. E. Hefford, Chief Inspector of Fisheries (Retired), Marine Department.

A review of the progress which has been made towards an understanding of fish and fishery problems in our marine and fresh waters: the relation of such research to fundamental hydro-biological factors and its bearing upon economic and utilitarian questions.

Observations on the Fat Content of Eel.

By F. B. Shorland, Dominion Laboratory, Wellington.

Using eels of 50 cm. and above, the length—weight relationship of A. australis was found to be linear. In A. dieffenbachii the first stage of growth differed markedly from the final stage in which the weight increase per unit of length was relatively some five times as great. The proportions of the body and the organs were not found to vary appreciably with weight while the oil (fat) content increased with weight. Just prior to migration the oil content was found to become much more uniformly distributed. The development of protein and fat conformed to that observed for mammals.

Bird Illustrators, Past and Present, with Reference to New Zealand.

This paper was divided into three parts: (a) Review of the Western World up to the twentieth century. With rare exceptions, after pagan times artists used birds as adjuncts not as the principal subject of their pictures. The eighteenth century saw the beginning of an era of bird-artists. (b) Review of Oriental art. In the greatest period of Chinese and Japanese art the pantheistic outlook of remarkable priest-artists led them to study birds as outward expressions of the Divine. (c) Brief review of bird-illustrations since 1900 including New Zealand work. A recapitulation of the salient requirements of an outstanding bird-illustrator.
