NoTES.^ — Leather Brown and Leather Brown O might almost equally 

 well be classed as ' moderately fast ' colours. Tii the first ' fading period ' 

 they become somewhat greyish in hue, but the altered colour fades very 

 gradually, leaving at the end of a year a fairly good drab-grey colour. 



Class III. Moderately Fast Colours. (Wool.) 



The colours of this class show distinct fading at the end of the second 

 period (August 22 to September 29, 1896), which becomes more pro- 

 nounced at the end of the third period (September 29 to November 5, 

 1896). A pale tint remains at the end of the fourth 'period of exposure' 

 (November 5, 1896, to May 22, 1897), and at the end of a year's exposure 

 the colour has entirely faded, or at most only traces of colour remain.
