 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 formi

It is interesting to observe the comparatively slow growth 

 of science along some lines and to see how most important facts 

 are overlooked until attention is attracted to them by some 

 great event that appeals to many minds at once and causes a 

 great awakening. The large mortality from typhoid fever 

 during the late Spanish-American war has created a wide- 

 spread interest in the subject of the transmission of disease by 

 insects, and man}- important papers have recently appeared 

 bearing on this subject. At the present time the importance 

 of these studies and observations is fulh- recognized, and there 

 is absolutely no doubt that insects play a most important part 

 as aetological factors in disease. To show the comparatively 

 slow growth of the subject, it may be mentioned that in 1807 

 Dr. John Crawford, in the "Baltimore Obser\-er," published 

 a paper on the * ' Mo.squital Origin of Malarial Disease. ' ' The 

 "New Orleans Medical and Surgical Journal," vol. iv, pp. 

 563-601, 1848, contains an article bj' Dr. Josiah Nott, in which 

 he mentioned that the ' ' mosquito of the lowlands' ' was the 

 cause of malaria. In 1871, Dr. Joseph Leid}' stated his belief 

 that hospital gangrene was disseminated by house-flies (Proc. 

 Acad. Nat. Sci. Phila. , 23, 297 ). Dr. A. F. A. King deser\-es 

 great credit for his brilliant article published in the ' ' Popular
