 paper should be taken off to renew the air at the surface. 



It is advisable, to have these waters in the most concen- 

 trated state possible, so that their surface may be covered 

 with a stratum of the volatile oil of the vegetable, which 

 raay afterward be separated by filtration. If the spoiling of 

 distilled waters cannot wholly be prevented by these means,

 alcohol, and the liquor filtered while hot, a yellowish white 

 grumous substance is precipitated. If Mr. Cuchoiz did not obser-ve 

 ihis, it was probably owing to the small quantity, on which he 

 operated. He employed only 20 grs. of ambergris to six draclims
