Otago Institute. 583 



districts had been depopulated by it, and the same thing had oocurred 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.
