 The desirability of killing as many as possible, especially in the 

 spring before they have had time to breed, was insisted upon, 

 and steps which should be taken to this end were described- 

 One efficacious method is : " Keep a soup-plate with a piece of 

 bread, upon which the flies can alight to drink, nearly covered 

 with sweetened milk and water, in which is mixed a teaspoonful 

 of formalin, all other liquids being removed. In the early morn- 

 ing the flies will take their fatal draught." Protect all food 

 with wire gauze or muslin, particular care being taken in cases 

 where there is sickness in the house. All the principal points of 

 structure referred to in the lecture were illustrated on the screen, 

 and figures of the various species of flies other than the common 

 house fly were shown and brief directions given for their recogni-

 extremely useful lecture, the vote of thanks being confirmed 

 by acclamation.

 death of Mr. Alpheus Smith. As most of them would remember, 

 he had been hon. librarian of the Club, and had held the office 

 for forty years. He was eighty-seven years of age. The an- 

 nouncement was received by those present standing as a mark 

 of respect, and the Hon. Secretary was directed to write a letter 

 of sympathy and condolence to the family of Mr. Smith.
