ring or hoop should be not more than 11 to 12 in. in diameter, of as slight as wire as i compatible with rigidity, and the instrument when put together should be well balanced, and in no case top-heavy.
The cigar-box to contain the specimens should be divided by a partition transversely to its length, and must be filled with envelopes made after the following fashion : — Take some well glazed and fairly stout letter paper, cut it into rectangular pieces of differing sizes, which, when folded square, can be made by the aid of a pair of scissors and some gum into triangular envelopes, after the following pattern.

Then shake it out of the net, and drop it head foremost into an envelope of suitable size (too largo a one is as bad as a very small one), so that the costa (or fore margin) of the wings lies along the hypotenuse of the triangle (see Figure), and consign it to the box, with a bit of
