TAXIDERMY AND MODELLING 



Permanent Oil-, Water-, and Powder-Colours, with Prices 



{continued) 



Of the foregoing list, it may be remarked that Lamp Black, 

 although permanent, is of so sooty and dense a nature as to be 

 useful for " rockwork " only. ^ 



Prussian Blue, though given as a powder-colour, is not 

 permanent ; it is only fairly permanent when rubbed in dry, 

 but in oil or water it blackens in light and regains its colour
