The daily newspapers announced the death of Sir PATRICK 

 MANSON, in London, April 8, 1922. fie rendered two import- 

 ant services in ascertaining the mode of transmission of human 

 diseases. The first was in 1878, when he discovered the man-

 thus, as Howard. Dyar and Knab state, becoming "the dis- 

 coverer of the first recognized transfer of a disease organism 

 by mosquitoes." The second was when he "first clearly for- 

 mulated the hypothesis fof the role of carrier of malaria by

 characteristic malaria as a result. --P. P. CALVFKT.
