On dissection. — (If dissected note the contents of the

Record of specimen. — Private collection. No. 4, year 

 1901, preserved in formalin solution. (Specimens 

 may be preserved in various ways. Methylated spirit 

 is frequently used, but is not very satisfactory : the 

 specimens shrink considerably in it after a time, and 

 the colours become dull. Absolute alcohol exhibits 

 them best, but is expensive if used on a large scale. 

 Formalin is not a good preservative for snakes, though 

 it is comparatively cheap.^ Serpents should always be 

 preserved in fluid, never stuffed, as they never look 

 natural in this latter way.)
