348 REPORT—1896. 
The foliowing tables give the general result of the exposure experi- 
ments made during the year 1895-96, the colours being divided, according 
to their behaviour towards light, into the following five classes: Very 
fugitive, fugitive, moderately fast, fast, very fast. 
The initial numbers refer to the order of the patterns in the pattern- 
books. The S. and J. numbers refer to Schultz and Julius’s ‘Tabel- 
larische Uebersicht der kiinstlichen organischen Farbstoffen.’ 
In the case of colouring matters requiring mordants, the particular 
mordant employed is indicated in brackets after the name of the dye- 
stuff. 
Crass I. Very Fucitive Cotours. (Wo0t.) 
Many of the colours of this class have faded so rapidly that at the end 
of the first ‘fading period’ (July 19 to August 12, 1895) only a very faint 
colour remains, and at the end of the fifth period (one year) all traces of 
the original colour have disappeared, the woollen cloth being either white 
or of a yellowish or greyish appearance.
