Mr. Gage by Donald Dan. They were taken on the cliffs of the north side of 
the island. ]

ALCA BRUENNICHI (Sabine). 
BRUNNICH’S GUILLEMOT. 
§ 4853. Three —Cape Dudley Digges, North Greenland. 
From Mr. Green, 1846. 
Mr. Green had many, sent by a gentleman who had them from 
Mr. John Hancock. I saw them unpacked. 
(These are the eggs mentioned in the next entry. Mr. Wolley gave a 
fourth to Mr. Rowley. The gentleman was very likely Mr. Wilmot. ] 
§ 4854. Twelve.-—Cape Dudley Digges. From Mr. Hancock, 
1846. 
If I remember right, Mr. Hancock informed me that a great 
quantity of these were brought to him ina ship from the north. 
Besides these twelve I have cthers [§ 4853] that I bought of Green, 
who had lately received them from some correspondent, who got 
them from Mr. Hancock, and let me have them for a trifle. I heard 
that Mr. Hancock received the eggs unblown. Hence probably the 
stains upon many of them. All these, as well as those from Green, 
bear the test of “ shining to the light,’ mentioned by Mr. Hewitson 
(ed. 2, vol. ii. p. 403) ; but one or two are, | think, as “ elegant in 
form as the eggs of ” the Common Guillemot. 
[Mr. Hewitson wrote (ut supra) :—“ Mr. Hancock tells me, after examining 
several hundred specimens, that however white the ground-colour may 
appear to be, the shells of these eggs, upon holding them to the light, are 
always dyed with greenish blue, which is not the case with eggs of the 
Common Guillemot.” It would seem (§ 4855) that these eggs, or some of 
them, were received by Mr. Hancock so long ago as 1839. }
