48 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 12 



Mr. W. D. Pierce: The laundry report in full, which is a co- 

 operative report with the Quartermaster's Department, will be pub- 

 lished in January. I do not know that it will be printed in any of the 

 Entomological Journals. It gives an entirely new phase to Sanitary 

 Entomology; that is, its application to industry. We have just found 

 that by lowering the specific gravity of the oil used in dry cleaning es- 

 tablishments we can bring about control. 



Mr. E. H. Gibson: I have been in charge of the insect work in 

 one of our largest cantonments during the past nine months and wish 

 to take this opportunity to express my appreciation of the excellent 

 work and the interest taken by Dr. Pierce in activities along the line 

 of insects in relation to health and for the class which he has conducted 

 in Entomology. 



Mr. W. a. Riley: In this connection, I feel compelled to say 

 that it is unfortunate that many of these reports that have been made 

 during the past few months are not going to be more widely available. 

 At the outbreak of the war, Mr. Moore, of Minnesota, was asked to 

 take up this line of work, and with thorough generosity, the authorities 

 there gave him all of his time and all facilities for doing this work. 

 He has published a few brief papers, and one of the very important 

 ones which is about to appear is one showing that apart from disease 

 transmission, the louse problem is of more interest to the medical man 

 than has been supposed, that gross infection of lice is an actual cause 

 of persistent fever, and in one case, one of those experimented on, it 

 showed very serious results. We feel confident that if the man had 

 been subjected much longer to the experiment, it might have resulted 

 even fatally. 



In other words, that without any disease transmission at all, the 

 bite of the louse itself was a serious thing, when it came to gross infec- 

 tion, and we have since had a paper from a medical man who ob- 

 served a similar case in San Francisco and who did not interpret it 

 until he received these results. These reports of Mr. Moore's, of 

 course, have been made constantly to the Bureau and to the -author- 

 ities in Washington, but unfortunately they have not been published 

 in any extended manner. 



Mr. W. D. Pierce : It might interest the association to know that 

 a complete bulletin will be prepared by the Bureau of Entomology on 

 the louse problem. 



Mr. W. C. O'Kane: Dr. Riley, in speaking of fever being caused 

 by the bites of lice, I personally have had the experience of a pretty 

 high temperature brought on by too many jiggers in South America, 

 several hundred I imagine, followed by a fever lasting some days, etc. 



Mr. W. a. Riley: It is a peculiar fact that this condition has
