The Zoologist— January, 1871. 2429 



May 5, They have all returned ; I observe that they do not stay 

 when the wind is east. 



„ 8. They are all away again. 



„ 9. They are all returned again, puffins, razorbills and 

 guillemots. 



,, 11. Their numbers have been greatly increased. 



„ 17. I got fifteen guillemots' eggs to-day ; they are about a 

 week later this year than last; last year being earlier than a series 

 of years past. 



„ 20. Got 183 eggs for eating and preserving to-day, as also 



five puffins' eggs; they have all commenced to lay nearer one time 



than they have done for three years past, for when they came to 



stay this time they came all together. 



If the wind blows strongly from the north, north-east, or east, if 



the roclv birds have laid no eggs, they all go away, for as the 



Mingalay and Bernera precipices face the south and west, the birds 



cannot rise from the rocks so well. ^,^„. r< wr.^^^^

[In the ' Zoologist ' for 1868, Dr. Giintber has shown, and I believe to the 

 perfect satisfaction of ichthyologists, that the whitebait [Clupea alba) is the 

 young of the herring [Clupea Harenr/iis). The passage in the Report of the 

 Zoological Society which conveys this information is as follows : — " The 

 facts on which Dr. Giintber bases this conclusion are these : the dorsal and 

 ventral fins are situated as in the mature herring; the lateral scales are the 

 same in number ; there is the same arrangement of teeth on the vomer, the 

 same number of vertebrae, namely fifty-six, a number not found in any other 

 Clupeoid ; and finally, whatever the size of whitebait, they are never taken 

 in roe, and an adult or mature fish has never been seen." (S. S. 1323.) 

 Now, in this paper of Mr. Walker's {ante, p. 2427), he speaks of " soils, or 

 young herrings," as something familiar to the fishermen of the North 

 Atlantic ; and the existence of such a fish either proves the " soils " are not 

 young herrings or entirely disposes of Dr. Giinther's theory : it wo\ild be a 

 matter of the greatest possible interest to procure a few of these little fishes 

 and transmit them to Dr. Giintber for examination." — Edivard Xewman.]
