FormtiLv, p. 2(1). Cliloroform is injurious fo some delicate 

 stains, but is in other respects an excellent de-alcoliolisation 

 agent, as it will take up a good deal of water, if any be left 

 in the preparations. I consider it too volatile to be safe to 

 use before balsam. Xylol is the best of these in that 

 respect. 



Both xylol and toluol are liable to become acid if kept in 

 only partially filled vessels.
