"A few days, perhaps a week, after the four trials, and on the _7th of June_, I rose early in the morning for the purpose of taking a mess of fish for breakfast, pulled to the usual place, baited with crabs, and commenced fishing, the wind blowing too strong for profitable angling; nevertheless on the first and second casts I fastened the two fishes, male and female, that I write about, and such were their liveliness and strength that they endangered my slight trout rod. I, however, succeeded in bagging both, though in half an hour's subsequent work I got not even a nibble from either this or any other species of fish. I determined to change the bait, to put upon my hook a portion of the fish already caught, and cut for that purpose into the larger of the two fish caught. I intended to take a piece from the thin part of the belly, when what was my surprise to see coming from the opening thus made _a small live fish_. This I at first supposed to be prey which this fish had swallowed, but on further opening the fish I was vastly astonished to find next to the back of the fish and slightly attached to it _a long very light violet bag, so clear and so transparent that I could already distinguish through it the shape, color, and formation of a multitude_ of small fish (_all facsimiles of each other_), with which it was well filled. I took it on board (we were occupying a small vessel which we had purchased for surveying purposes). When I opened the bag, I took therefrom _eighteen_ more of the young fish, precisely like in size, shape, and color the first I had accidentally extracted. The _mother was very large round her center and of a very dark-brown color, approaching about the back and on the fins a black color, and a remarkably vigorous fish_. The young which I took from her were in shape, save as to rotundity, perfect miniatures of the mother, formed like her, and of the same general proportions, except that the old one was (probably owing to her pregnancy) much broader and wider between the top of the dorsal and the ventral fins in proportion to her length than the young were. _As to color, they were in all respects like the mother, though the shades were many degrees lighter._ Indeed, they were in all respects like their mother and like each other, the same peculiar mouth, the same position and shape of the fins, and the same eyes and gills, and there cannot remain in the mind of any one who sees the fish in the same state that I did a single doubt that these young were the offspring of the fish from whose body I took them, and _that this species of fish gives birth to her young alive and perfectly formed, and adapted to seeking its own livelihood in the water. The number of young in the bag was nineteen_ (I fear I misstated the number in my former letter), _and every one as brisk and lively and as much at home in a bucket of salt water as if they had been for months accustomed to the water_. The male fish that
