Each consists of an oblong plate, perforated with large holes in a regular manner, and having a projection on its surface near one extremity, to which is jointed a second piece, having tlie most singularly true resemblance to an an- chor.

Among the multitude of transparent creatures that swim in the open sea, few are more interesting than those which constitute the infant state of the very ani- mals that we have lately been examining—^the Sea- urchins and their allies. It is a productive way of ob- taining subjects for microscopic research, to go out in a boat on a quiet summer's day, especially in the after- noon, when the sun has been shining, or when evening is waning into night, and with a fine muslin net stretched over a brass ring at the end of a pole, skim the surface of the smooth sea. At intervals you take in your net, and having a wide-mouthed glass jar ready, nearly filled with sea-water, invert the muslin in it, when your captives, small and great, float ofi' into the receiver. After a few such essays, unless you have very bad success indeed, you will see even with the naked eye, but much more with a lens, that the water in your jar is teeming with microscopic life; and though many of your captives will not long sur- vive the loss of their freedom, still meanwhile you may secure many an interesting object, and examine it, .
