flesh separates freely from the bone. In 

 scraping the bones care must be taken not to 

 disturb the ligaments which unite the bones 

 together, as these, when dry will be sufficient 

 to keep each bone in its place. Should any 

 of the bones become detached, they 

 may be united again by boring a hole 

 through the end of each, and passing a piece 

 of brass wire through the holes, and twisting 

 the ends together. When all the fleshy parts 

 are taken away, and the bones bleached by a 

 solution of quick lime, and drying in the sun, 

 the whole may be mounted upon a board, 

 using two strong wire pillars as supports for 

 the back bone. Very large animals must 

 have each bone cleaned separately, and then 

 united again by brass wire as before mention- 

 ed, or in very large bones with a small brass 

 bolt and thumb screw. Inspection of speci- 

 mens in a museum will show at once how 

 they should be mounted. 



POLISHING HORNS AND HOOFS.— 

 These may be polished in the following 

 manner : — File cut, and scrape the horn down 

 to a level surface, taking care to go through 

 the epidermis to the hard substance, then use 

 sand-paper, beginning with coarse and work- 

 ing down by degrees to the finest quality. 

 Then use putty powder (oxide of tin) and 

 oil, applied with a rag, working well and 

 giving plenty of friction, finishing off with a 

 fine cotton rag, a wash leather, or the palm 

 of the hand.
