 Tayloe, T.— Clearing fluid. 



[About equal parts of Squibb's absolute alcohol and Eucalyptus oil forms a 

 very good clearing fluid for animal or vegetable tissues. When the tissues 

 are freshly cut, place them in commercial alcohol for a few minutes. Next 

 transfer them to the clearing fluid, as above described, for a period of 

 about ten minutes. They are next placed in pure Eucalyptus oil, which 

 removes the alcohol ; a few minutes' immersion will suffice. It is not 

 well to keep tissues longer than necessary in the fluid. Vegetable tissues 

 become hardened when kept several days in it]
