Fourth Meeting: 13th August, 1907.
The President, Dr. R. Fulton, in the chair.
New Member.—Dr. Russell Ritchie.
Exhibits.—Professor Malcolm gave an account of certain optical illusions produced by lines drawn at various angles to one another, and by parallel lines crossed obliquely by lines at different angles, &c.
Professor Benham exhibited, on behalf of Mr. G. M. Thomson, cases made by the larva of the moth æceticus omnivorus, in which black thread was woven with the usual materials.
Professor Benham also exhibited a method of mounting models of aquatic animals in glass cases in such a way as to represent water.
Dr. Hocken showed a Boyle's tube, for illustrating the method of formation of dew and rain.
Dr. Marshall gave an address on “The Volcanoes of the Taupo Region.”
He prefaced his remarks by mentioning that he had spent some portion of last summer in this volcanic district, but he did not intend to enter into a full description of it. There were certain features connected with the district from which certain inferences could be drawn, and a comparison could be made with other areas, and to some extent a relationship traced between New Zealand and other parts of the world. There were many theories about the isolated position New Zealand occupied, but it was not so isolated as it was supposed to be. By the aid of the lantern he showed a large number of pictures of the volcanoes of the North Island, upon which he made a running commentary.
Dr. Fulton, by means of the lantern, showed a cock-pit, said to be several hundreds of years old.
In 1849 the sport was finally abolished, but in 1860 it was carried on in Dunedin by educated gentlemen.
Professor Park gave a description of visits he had made to the volcanic region of the North Island, and thought Dr. Marshall deserved a hearty vote of thanks for his address.
