MAMMALS AND BIKDS OF PKINCK OF WALES SOUND. 123 



Red-'ihroated Diver (Coli/mbus Septenlrioiialis, L) Coxzoiv 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 w^ere 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 

 shoi'e 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 of the 

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

 I regret very much that more time could not Ibe devoted to the fjtudy 

 of these interesting branches of the Natural 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 Ontarift."
