192 THE ZOOLOGIST. 
“« Many think the Otter to be well nigh exterminated, and that its fate 
will soon be that of the Beaver and Yellow-breasted Marten, now no longer 
seen amongst us. But there is no ground whatever for this belief; Otters, 
as I will presently show, by testimony of unquestionable authority, are still 
as plentiful in our waters at the present day as they were fifty or sixty 
years ago.” 
The whole of this chapter, a long one, and the last in the 
book, will well repay perusal. 
Amongst the appendices which follow, the only one calling 
for notice in these pages is that on the Bibliography of Hunting 
already criticised. 
The two volumes on “ Fishing,” both by Mr. Cholmondeley 
Pennell, are devoted the one to Salmon and Trout, the other to 
Pike and Coarse Fish. On the whole, it may be said that these 
two volumes contain fewer observations on the natural history of 
freshwater fish than on the various methods of catching them, 
although we must not omit to state that in one of the volumes there 
is a long chapter on the natural history of British Salmonide. 
In this Chapter Mr. Pennell divides the different species of 
Salmonide into two groups: the silver or migratory, and the 
yellow or non-migratory ; the first group comprising those fish 
which migrate periodically to or from the sea, viz., the true 
Salmon, the Bull Trout, and the Sea Trout, and the second 
group those whose habits usually confine them to fresh water, 
lake or river, viz., the Common or Yellow Trout, the Great 
Lake Trout, and the Grayling. “ This grouping,” says Mr. 
Pennell, ‘commends itself not only by its simplicity and con- 
venience of classification, but also by such broadly-marked 
distinctions in regard to habits, localities, &c., as must override 
distinctions founded upon mere technical differences.” 
The remarks on Thames Trout (pp. 164-5) will have an 
interest for many persons besides professional anglers, and we 
shall be much mistaken if the practical advice given in the 
chapter on Thames Trout Fishing, by Mr. H. R. Francis (pp. 
410-33) does not make numerous converts to the gentle art 
amongst those who have hitherto been too fond of quoting the 
definition of a fishing-rod attributed to Dr. Johnson.
