1917 ENTOMOLOGICAL SOCIETY. 87 



Mb. Baird: I do not think anvthin*,' was ever reared from those; they were 

 in poor condition when they arrived as they were a long time in reaching the 

 laboratory. 



Prof. Caesar: I merely mention this matter because it is possible we are 

 not doing justice to the sarcopliagid flies. 



Dr. Hewitt: I tliink Mr. Totliill has raised both iachinids and sarcophagids. 



FRIDAY AFTERNOON. 



Mr. Winn : The programme is a very lengthy one and this year I think it 

 would again be advisable to dispense with the Presidential address. As practically 

 all matters connected with our season's work have been covered by our various 

 reports the address would be either largely repetition or else be merely a paper 

 and I have already read one. Before the programme was completed and found 

 to require all the available time, I thought of two subjects that might be of 

 interest. One was to show a series of slides that I had begun preparing with 

 Mr. H. M. Simms of our Montreal Branch, calling attention to the very curious 

 microscopic objects known in Europe as " battledore " scales or " bladder-scales " 

 of the Blue butterflies. These are found on the wings of the males only and are 

 much smaller than the regular wing scales and apparently each species has its 

 own characteristic size, shape and pattern of " battledore." We have not succeeded 

 in obtaining specimens of quite all the North American so-called species, but 

 with the kind assistance promised it is hoped that by the time Mr. Simms returns 

 from " somewhere in France " we may have an almost complete series to show. 



The other idea that occurred to me was in connection with the Society having 

 spread from a centre which was originally Toronto, then I^ondon, now Guelph, 

 always in Ontario, to a national Society extending from the Atlantic to the 

 Pacific. We have branches in Nova Scotia (represented by Prof. Brittain) the 

 Montreal Branch, Toronto Branch and the parent Society in Guelph, individual 

 members scattered through all the Provinces and a very flourishing Branch in 

 British Columbia. I thought the annual address might take the form of a com- 

 posite article by all the different branches regarding tlie insect collections of 

 the Dominion of Canada. I have spoken to Dr. Walker and he thinks this can 

 be arranged by a series of articles published in the Cdnadmn Enfonwlofjist as 

 part of the popular series now being printed. It w'ould be impossible to read such 

 a report at a meeting like this; I leave it for your consideration, and if found 

 feasible, your co-operation. 



CAMP HY^GIENE. 



Capt. G. J. Spencer, O.A.C, Guelph. 



The main object of military hygiene is to keep men liealthy, or else they cannot 

 march. In camp certain factors control this, such as food, work, exercise and tlie 

 condition of the body. As far as food is concerned, a Canadian soldier is fed more 

 generously than one of any other nationality, as -he is allowed five pounds of food 

 a day. Beef constitutes the invariable meat ration, because it can be more easily 

 obtained, is cheaper, and is more preferable to the men; potatoes, peas, beans,
