of the body. By this way the colors, which were bid- 
den under the scales will now begin to appear. The 
mouth must be kept open by a wad of cotton or paper. 
7. After the reptile is injected it must be neatly 
coiled up in lenghts according to the lenght of tube or 
bottle. 
When the ordinary tubes are used, care must be taken 
in hermetically sealing them. 
To do this, first cut the cork to the thickness of 1 — 
P /2 cm, then take hold of the cork with forceps (apin 
stuck in the top answers the purpose) and plunge it in 
boiling parafin wax, and while the wax is still warm, 
pross the cork into the tube, three or four mm. below 
the topedge of the tube. 
This leaves a small hollow space at the top, which is 
nearly fllled with water and piaster of paris is dropped 
into this until the water is absorbed. 
Now allow it to set, and when hard it must be cut 
off, level with the topedge of the tube. 
After the piaster of paris has become dry it must be 
blacked with iron lac, and the topedge of the tube should 
be lackered outside so that the cork does not show. 
The piaster of paris must be saturated with the iron 
lac so that any air spaces will be fllled by it, leaving 
the tube hermetically sealed 
Blue, green and yellow reptiles must be put in 93°/, 
spirit. Black, white, gray and brown ones are well pre- 
served in 10°/^ formalin.
