1908, one of which is in the University cabinet. ' The same collection 

 includes a Black-throated Blue Warbler, taken in Boulder Canyon, at 

 6,000 feet, Oct. 16, 1911. 



The bringing together of these records, even with Cooke's bulletins 

 as a basis, and the preparation of new descriptions and keys, has been a 

 great undertaking, but the work has been well done and deserves the 

 appreciation of ornithologists, both professional and amateur.

The Editor of 'The Auk,' 



Dear Sir: — For some time past I have been engaged in writing the 

 "Life of Sir WiUiam Jardine," the naturalist. 



I wonder if you would be so good as to insert this letter in your magazine, 

 in the hope that, if it caught the eye of any one who might be able to assist 

 me, either by letters from Sir William Jardine, or from personal acquaint- 

 ance, they might communicate with me. 



Yours truly, 



Hugh S. Gladstone.

 is frequently confused with the University of Colorado, a state institution located 

 at Boulder. References to the collections and records of both institutions occur 

 in Mr. Sclater's book. — J. H.
