pended in the vessel. We must take care to make 

 a little incision in the abdomen of animals with ver- 

 tebrae, that the liquor may penetrate into the inte- 

 rior of the body. M. Peron advises the use of 

 camphorated spirits, because the camphire augments 

 the preserving quality of the liquor, without adding 

 to its force. But besides that camphire is expensive 

 its dissolution makes the animals tough, and ren- 

 ders them difficult to dissect. It is requisite to add 

 to the liquor after the animal has been in it some 

 days, to ensure its preservation ; this precaution is 

 especially necessary for those which are most sus- 

 ceptible of corruption. We must then lute the 

 bottles ; we must have a luting, easily prepared, 

 which dries and acquires all its solidity even in the 

 moment of employing it, on which spirits of wine 

 has no effect, which does not scale offj which pene- 

 trates the pores of the stopper, and which perfectly 

 adheres to the glass. Cork stoppers are preferable 

 to all others, because those of glass often break by 

 the evaporation of the spirits of wine. 



The phial or bottle being well corked, the fol- 

 lowing is the luting, to which M. Peron has given 

 the name of lithocolle.
