MAMMALS AND BIRDS OF PRINCE OF WALES SOUND. 123 



Red-throated Diver (Col/jmbus Septentrionalis, L) Coxzow Esk. ; 



This bird arrived about June 20th and was often seen during the 

 summer. 



One nest only of this bird was seen a little above high -tide mark, 

 and the Eskimo informed me they could seldom be found. 



On August 7th, some fledglings were seen, and all had disappeared 

 by September 28th. 



Black Guillemot ( Uria grylle, L. ) 



This interesting little bird is seen here throughout the year, being 

 most numerous during the summer. 



During the coldest weather it was often taken on small pieces of 

 water, where the ice had been broken by the ever-changing tides. 



Quantities of eggs of this bird were brought to me by Eskimo 

 from an island about four miles from the coast, and fledglings were 

 seen on August 10th. 



Little Auk ( Mergulus alle, L.) 



■ A small number of these birds were seen some distance from the 

 shore during the summer, but nothing could be learned of them. 

 One specimen was taken. 



In conclusion it may be well to add that with the exception sof the. 

 Snowy Owl, specimens were taken of all the birds noted herein, and 

 I regret very much that more time could not be devoted to the btudy 

 of these interesting branches of the Natui-al History of Prince of 

 Wales Sound. 



Prof. Wright enquired whether Mr. Payne had seen any of 

 those extraordinary migrations which had been observed as 

 in the Case of the Lemming. 



Mr. Payne had not noticed any such changes in their 

 movements. So far as he was aware none had been observed 

 in North America. 



Dr. Ellis read a paper on "The Chemistry of the Natural 

 Waters of Ontario."
