Madder Dyeing. 141 



of the difference between these results, and those of Dr. 

 Runge appears to be, that in the former, river water was 

 employed, and by the latter distilled water was used. 

 When distilled water was substituted, the result was much 

 more favourable, but not such as to warrant us to say, that 

 the munjeet was much richer in colouring matter, than 

 Avignon, or Dutch madder. The addition of malt afforded 

 a still more favourable result. 



Opinion of Herrn B'ohm. — 1. With equal portions of 

 colouring matter, although munjeet gives a fine red, yet

Opinion of Herrn Nobiling. — The result of his trial was 

 not in favour of this dye. The shades produced were be- 

 tween those of madder and lac dye.

 and rather emaciated in his appearance, applied at the 

 North Dispensary, in the expectation of being admitted as 

 an in-door patient. He was rather brought there by his 

 poverty than by any particular urgency of his symptoms ; 

 he spoke very little English, which prevented me from col- 

 lecting any accurate particulars of his history previous to 

 the present disease. He states that about 12 months ago 

 he was seized with pains of the joints and limbs of both 

 upper and lower extremities, which were accompanied by 

 eruptions of what he termed Roth FLecke, of which he 

 shewed some on his chest. The pains had continued until 

 he had lost, in a great measure, the power of his hands, 

 which he uses as if labouring under partial paralysis of the
