The sub-title of this paper is " What Farmers can do to Assist in the Cam- 

 paign against Flies and Mosquitoes." The work is well designed for instruc- 

 tion in this particular, as regards the United States, and farmers even in this 

 country often have to deal with mosquitoes in the summer, especially in 

 certain parts. The author does not appear to have read all the large literature 

 either on malaria or on yellow fever ; but the instructions for practical work 

 will be useful.
