(In this department, also, an infinite variety of specimens may be made. Thus the smaller animals may be steeped or kept in spirit, or their skins removed and dried, or skeletons made, or their bones, or their teeth, placed side by side. Skeletons may be made by removing all the muscles with scissors and forceps, then placing the animal in water for a few days till the bones are colourless, then allowing the ligaments which bind the bones together gradually to dry, the animal being placed in the position required for preservation. The bones may also be kept separate; thus the skulls may be placed side by side, or the bones of the spine or limbs. Bones are easily prepared by placing the animal in water, and allowing decomposition to separate the soft parts from them. It would be very interesting, for example, to see side by side a series of arm-bones of different animals, as the mouse, shrew, mole, bat, squirrel, rat, rabbit, hare, &c. &c. Small skeletons may be made by first removing as much as possible of the soft parts, and then putting the animal, in its proper position, in a box with holes in it, and placing it close to an ant's nest.)

• The foregoing “ Notes" having been placed in the hands of PROFESSOR OWEN, he kindly wrote the following letter to the Editor :

“ BRITISH MUSEUM,

14th February, 1866. DEAR MR. TOYNBEE,

I have carefully revised the annexed Instructions, and find scarcely any topic to add or suggest to a summary so complete and exhaustive.

British Natural History would make a sure and rapid advance were every Parish stimulated and instructed to observe and collect, as Wimbledon has been by you.

Sincerely yours, J. TOYNBEE, Esq., F.R.S.” RICHARD OWEN.

Cox & Wyman, Printers, Great Queen Street, London, W.C.
