the neck and tail, and other bones of the back, in position. 
Next, force a wire through the hollows in the bones of the 
tarsi, tibia, and hips (Plate X. k, y, j) by drilling a hole 
through each end; now fasten this wire to the broad bone 
that covers ‘the back (m), by drilling a hole through on 
each side and bending the wire down firnily (x), first over 
then under the bone, where it meets the end of the oppo- 
site wire; twist the ends together. The wing, breast, and 
other bones are now fastened on by drilling holes trans- 
versely through the ends and running wires through and 
twisting them (r, d). 
The skeletons of mammals, fishes, etc. are mounted in 
much the same manner. If large, they are supported on 
iron rods. The wire used must be composed of brass or 
copper, as iron corrodes easily. The fleshy or cartilaginous 
parts of the feet should be removed, but not the outer or 
horny portion of the bill.
