Semi-albino Song-Sparrow.— Mr. C. H. Young, of 

 Hurdman's Bridge, has shown me a very beautiful specimen of 

 a male song-sparrow, which he shot this spring (March 26th) 

 near his house. The head and shoulders are white, as is the 

 whole lower surface with the exception of the patch of feathers 

 on the breast, In this specimen these feathers are darker than 

 usual. The wing coverts and secondaries are beautifully and 

 symmetrically marked with brown and white Primaries white. 

 Tail and tail coverts brown. The specimen has been beautifully 

 mounted by Mr. Young, who is a skilful taxidermist, and will 

 be exhibited at one of the evening meetings next winter. — J.F.

SUGAR : ITS CHEMISTRY AND MANUFACTURE. 



The honour of delivering a popular lecture at the recent 

 convocation of Queen's University was conferred upon Dr. Adolf 

 Lehmann, who for several years was Assistant Chemist of the 

 Experimental Farms, and therefore personally well known to 

 many of our Ottawa members. Since his return from Leipzig, 

 Dr. Lehmann has been lecturing on organic chemistry and allied
