 It must be conceded, however, that anion »• physicians there exists a 

 difference of opinion, rehitively unimportant in its practical bearings,

 railway employees and others, with announcements in the daily papers 

 of the dates of these meetings and the programmes of speakers.

 INIusemn and the New York Academy of Sciences, I undertook 

 an ethnological expedition to the Chipewyan Indians of Lake 

 Athal)asca. Leaving New York on the oth of May, five days' travel 

 brought me to Edmonton, probably the greatest fur-mart of the world 

 and the northernmost point that can be reached by rail. It was at this 

 place, in the office of the Hudson's Bay Company, that I completed my 

 camping outfit and procured the two articles considered the most essen-
