ENTOMOLOGICAL NEWS. 



[The Conductors of Entomological News solicit and will thankfully receive items 

 of news likely to interest its readers from any source. The author's name will be given 

 in each case, for the information of cataloguers and bibliographers.] 



To Contributors.— All contributions will be considered and passed upon at out 

 earliest convenience, and, as far as may be, will be published according to date of recep- 

 tion. Entomological News has reached a circulation, both in numbers and circumfer- 

 ence, as to make it necessary to put " copy " into the hands of the printer, for each num- 

 ber, three weeks before date of issue. This should be remembered in sending special or 

 important matter for a certain issue. Twenty-five "extras," without change in form, 

 will be given free, when they are wanted ; and this should be so stated on the MS., along 

 with the number desired. The receipt of all papers will be acknowledged.— Ed. 



Philadelphia, Pa., May, 1906. 



Several times we have published comments on articles 

 noticed in medical journals and called attention to the neces- 

 sity of medical colleges giving a course on the principles of 

 entomology, in view of the fact that so many diseases are 

 carried by insects. The quotation below is from the April, 

 1906, "Medical Brief," page 282, and carries us back before 

 the time of Dr. Francesco Redi, who lived about 161 8. It has 

 been questioned whether such a statement as that in the 

 " Brief" is meant seriously, but from articles we have seen in 

 other medical journals and from conversation with some medi- 

 cal men there can be no question about it. 



"Take the human seed germs (spermatozoa), put them 

 upon a plate, first spreading some alkaline nourishment upon 

 the plate ; for instance a little soap, place the plate in a room 

 of proper temperature, and in sixteen to twenty-four hours, 

 swarms of ants will be running about. In other words, these 

 living human germs placed under this different condition other 

 than the mother soil, develop into ants. These little fellows 

 can be watched and be seen to gradually develop and start off 

 on the run. This would evidently appear that living germs, 

 when placed by accident, or otherwise, under very different 

 conditions, produce very different forms of life. But what 

 relationship do we owe to the ant ? Perhaps this is why the 

 claim is made that the ant has more characteristics of the 

 human being than any other animal."
