[AMR/TON D. SMITH. 



I think any one who will adopt the mode of mounting on the 

 cover, and subsequent heating-, as above described, whatever 

 may be the rest of the procedure, will never consent to give up 

 this part, since it effects so even a distribution, and such de- 

 struction of residual organic matter, and gives such inert 

 brilliancy to the preparations; sometimes, if the acid has not 

 been thoroughly washed out of acid treated specimens, snappy 

 explosions will occur when the alcoholic mixture is heated; oi 

 course, the remedy is to pour off, and replace with pure water 

 and alcohol.
