than with Hcematoxylhi^ as a gradual fading does not, according to 

 Dr. Mayer's experience, afterwards take place. Objects preserved in 

 osmic acid do not stain well unless they are previously bleached, as 

 before explained. 



In the endeavour to use other means of staining with alcoholic 

 solutions, Dr. Mayer has Conducted a series of experiments on the 

 ordinary dyewares of commerce, but has not been able to obtain very 

 satisfactory results. Grenacher has found it necessary to dye with 

 carmine in an alcoholic solution, and for this purpose he uses a fluid 

 got by boiling carmine in alcohol and hydrochloric acid. According 

 to Dr. Mayer's experience this fluid appears in many cases to dye 

 stronger than cochineal, but without warranting the same precision.
