TABLE XXI. 
The following species are said to be, or to have been, used in dyeing ; 
but they have not, in my hands, yielded reactions indicative of 
useful dye agents. 
Alectoria jubata. No change of colour was produced by chloride 
of lime ; the colour of the alcoholic solution and 
the effect of ammoniacal maceration, even for 
the lengthened period of a year, was a light 
brownish-yellow. 
sarmentosa. The colour of the alcoholic solution, and the 
reaction of chloride of lime and ammonia, was 
a greenish-yellow. 
Lecidea geographica Yielded the same results. 
Also yielded similar results ; with the excep- 
tion that chloride of lime bleached the alcoholic 
solution of the former, and made no change in 
J that of the two latter species.
