done with a much diluted Delafield's hematoxylin, followed by 

 a weak solution of picric acid in alcohol. After all the other 

 fixatives the sections were overstained in Weigert's hematoxylin, 

 decolorized in water acidulated with HCl, and counterstained in 

 a weak solution of Orange G in distilled water! The blood cells' 

 are clearly differentiated by either method; the cytoplasm of 

 those containing even a trace of hemoglobin shows some tinge of 

 yellow. Developing muscle tissue and nerve fibers also are yellow. 

 Other elements are stained by the hematoxylin, the delicate 

 processes of the irregular mesenchymal cells showing especially 

 well.
