" The results of the dissection of these three sorts were as follows : — 



" 1st examined, was in good order, fat ; a male : milt small ; 3 inches 

 long by J inch broad : food Entomostraca. 



" 2nd, a male ; in most respects as preceding : food Entomostraca. 



" 3rd, a male ; as above : stomach empty ; intestines clean and quite 

 empty. 



" 4th, in fine order, as above ; a male : food Entomostraca. 



" 5th, a female ; in all other respects as those already examined : 

 food, 1st, Entomostraca, abundant, minute; 2nd, two small prawns. 



" 6th, a female ; in other respects as above : food Entomostraca, of 

 two kinds ; one extremely minute. 



" 7th, a female ; the fish in the highest order : food Entomostraca. 



" 8th, a male, 9j inches long : milt longer than in those described ; 

 4 inches long by J inch broad : food Entomostraca. 



" 9th, a male ; as in the first seven : food Entomostraca. 



u 10th, a female; in the best order: food Entomostraca. 



" 11th, ditto ; ditto : food Entomostraca, of a large species and 

 greenish colour. 



" 12th, length 7 inches ; of very inferior quality, soft ; seemingly a 

 young fish, yet tolerably fleshy ; a female : food Entomostraca. 



"The 13th, 14th and 15th specimens were in as good condition 

 seemingly as those described, but although taken early this morning 

 the viscera by 5 p.m. were found to be putrescent : food Entomostraca. 



" Thus, the quality as to food of the natural family of the Clupea 

 depends — 1st, on species; 2nd, on their food; 3rd, on their condition 

 as to the state of the milt and roe. Their natural habitat is the deep 

 sea, where they find their natural food — the Entomostraca." 



Lastly, I availed myself of the assistance of my much esteemed 

 friend and former student Mr. Henry D. Goodsir, now, alas ! with Sir 

 John Franklin. This gentleman with his more celebrated brother, 

 Mr. John Goodsir, were my favourite students and assistants in my com- 

 parative anatomical pursuits, in consequence of their fondness for such
