strongest men I have ever known. He was not intemperate, but he lived luxuriously, and waded as a salmon fisher for many years in this very river; but before he was fifty, palsy deprived him of the use of his limbs, and he is still a living example of the danger of the system which you are ambitious of adopting.

ORN.--Well, I give up the wine, but I intend to wade in Hancock's boots to morrow.

HAL.--Wear them, but do not wade in them. The feet must become cold in a stream of water constantly passing over the caoutchouc and leather, notwithstanding the thick stockings. They are good for keeping the feet warm, and I think where there is exercise, as in snipe shooting, may be used without any bad effects. But I advise no one to stand still (which an angler must do sometimes) in the water, even with these ingenious waterproof inventions. All anglers should remember old Boerhaave's maxims of health, and act upon them: "Keep the feet warm, the head cool, and the body open."

*PHYS.—I am sorry we did not examine more minutely the weight and size of the fish we caught, and compare the anatomy of the salmon and the sea trout; but we were in too great a hurry to see them on the table, and our philosophy yielded to our hunger.

-

HAL. We shall have plenty of opportunities for this examination; and we can now walk down to the fishing house and see probably half a hundred fish of different sizes, that have been taken in the cruives, this evening, and examine them at our leisure.

PHYS. I never saw so many fish of this kind before; and I conclude that heap of smaller fish is composed of trout.

HAL. Certainly. Let us compare one of the largest trout with a salmon. I have selected two fresh run fish, which, from their curved lower jaws, are, I conclude, both males. The salmon you see is rather broader, has a tail rather more forked, and the teeth in proportion are rather smaller.

SEA TROUT SALMO ERIOX.!

The trout, likewise, has larger and more black and brown spots on the body; and the head of the trout is rather larger in propor tion. The salmon has 14 spines in the pec toral fins, 10 in each of the ventral, 13 in the anal, 21 in the caudal, and 15 in the

dorsal. The salmon measures 38 inches in length, and 21 inches in girth, and his weight is 22 lbs. you see. The trout has one spine less in the pectoral and two less in the anal fin, and measures 30 inches in length, and 16 inches in girth, and his weight is 11lbs. We will now open them. The stomach of the salmon, you see, contains nothing but a little yellow fluid, and, though the salmon is twice as large, does not exceed much in size that of the trout. The stomach of the trout, unlike that of the salmon, is full of food: we will open it. See, there are half digested sand eels which come out of it.

PHYS.-But surely the stomachs of salmon, must sometimes when opened contain food?

HAL. I have opened ten or twelve, and never found anything in their stomachs but tape worms, bred there, and some yellow fluid; but I believe this is generally owing to their being caught at the time of migration, when they are travelling from the sea upwards, and when they do not willingly load themselves with food. Their digestion seems to be very quick, and their habits

seem to show, that after having taken a bait in the river they do not usually offer to take another, till the work of digestion is nearly

performed; but when they are taken at sea, ⚫ and in rivers in the winter, food, I am told, is sometimes found in their stomachs. The sea trout is a much more voracious fish, and, like the land trout, is not willingly found with an empty stomach.

PHYS.-I presume the sea trout is the fish called by Linnæus, in his Fauna, Salmo Eriox?

HAL. I know not: but I should rather think that fish a variety of the common salmon.

PHYS.-But there are surely other species of salmon that live in the sea and come into our rivers: I have heard of fish called greys, bull trout, scurfs, morts, peales, and whitlings.

HAL. I have never been able to identify more than the salmo salac, or salmon, and salmo trutta, or sea trout, in the rivers of Britain and Ireland. The whitlings, I believe to be the young of the sea trout. A
