districts had been depopulated by it, and the same thing had occurred in America. The subject was one of immense importance to the world, and particularly to our Empire. Some of the guesses in the past regarding the cause of this disease had been singularly near the truth, and modern scientific research had proved up to the hilt that the mosquito grew the germ in its own tissues, carried it to human beings, and infected them with the disease. It was not every kind of mosquito that did this, but only Anopheles. Investigations showed clearly that this was actually the case, and it had been thought possible to stop the disease by destroying the mosquitoes. Some good had been done in this way by draining swamps and otherwise destroying the insects, but it was found that they were not easily dealt with. The speaker explained his subject by means of some very fine diagrams, and also exhibited a number of books and periodicals containing accounts of scientific research into this subject. A short discussion took place, and a hearty vote of thanks was passed to Dr. Colquhoun for the clear and highly interesting manner in which he had dealt with the subject. Second Meeting: 11th June, 1901. Mr. G. M. Thomson; President, in the chair. The President communicated to the Institute a letter from Mr. Morton, local secretary at Hobart for the Australasian Association for the Advancement of Science, giving some account of the programme of the meeting to be held in January, 1902. The President laid before the Institute a scheme for compiling a faunal census for New Zealand in collaboration with the other Affiliated Societies.
