If a snake is "stuffed," it stretches the scales apart most unnaturally, and never looks like life. For this reason, the clay-covered manikin is necessary, in order that any excess of skin may be modeled down upon it, and the scales be made to form an unbroken covering.
LACERTILIA: _The Lizards._--With the exception of the iguana, the gila monster, mastigure, and a few others, the lizards are so small and slender, and have tails so tapering out into thin air that they are altogether too small to be mounted by the ordinary methods of taxidermy. The finest method ever devised for the preservation and display of small reptiles and batrachians is that adopted by the Museum of Comparative Zoology, Cambridge, Mass. Each specimen is preserved in clear spirits in a jar by itself, and instead of being dropped in head first to sink or swim, and tie itself into a bow-knot if it can, the reptile is placed (in the flesh) on a thin, rectangular slab of plaster Paris or cement, of the tint best suited to the display of the specimen. The object is placed in a life-like attitude and held in place by threads which pass through holes in the slab and tie the feet down securely. The accompanying illustration (Fig. 54), drawn from a specimen, and the following description, both of which have been kindly furnished me by Mr. Samuel Garman, Curator of Reptiles, Museum of Comparative Zoology, will enable any intelligent preparator to adopt this admirable method:
"It was in 1875 we began to mount the reptiles and batrachians of the Museum of Comparative Zoology on tablets, in alcohol. Before that date they had been stuffed and dried, a method which proved rather unsatisfactory, especially so in regard to color, and the shrivelling of digits and tails. However varied at first, the appearance soon became uniform and dusty. Mounting in the alcohol does away with the most serious objections; we can give the specimens life-like attitudes, or arrange them in groups as if playing, courting, or fighting; and the liquid heightens their beauty, as the water does that of the pebble at the seashore, while ravages of insects are entirely out of the question.
