"pERSONS curious In preferving fpecimens for natural. 

 -*" hiftory are often diiappointed by the evaporation of 

 the fplrits, which occefions the lofs of the fubjedl intended 

 to be preferved, or they muft be very careful in often exa- 

 mining their bottles, or putting fpirits in fuch as they have 

 occafion for a frefh fupply, which, in a large collection 

 requires much time, trouble and expence. This induced 

 M. de Reaumur to try many experiments, in order to ob- 

 viate this inconvenience; which he gave to the public in 

 a long differtation, inferted in the Memoirs of the Royal 

 Academy of Sciences, for the year 1746^ after mention- 

 ing his different trials, he recommends two methods. 



The firft is, to get bottles with glafs ftoppers of a conic 

 form in the part that enters the neck of the bottle, and 

 broad and fiat at the other end. Whenthe fpirits and fpe- 

 cimen, fupportcd by a piece of wire, are put in, a little 

 mercury muft be thrown into the boille, and the floppev 

 fixed in it's place, and fecured by a piece of bladder or lea- 

 ther tied round it and the neck of the bottle; the whole 

 muft be reverfed and placed on the broad end of the flop-- 

 per, which occafions the mercury to fettle between the 

 neck of the bottle and ftoppcr, and obftrudsthe evapora- 

 tion of the fpirits by the only paffage through wdiiclx the
