26 DISSERTATION ON THE 



solutions were examined, and exhibited the 

 following habitudes, with re-agents. The so- 

 lution obtained from the flowers with car- 

 bonate of potash caused a brown colour; it 

 foniied a precipitate with barytic water ; with 

 an infusion of litmus, a faint red appearance ; 

 both the acetate and nitrate of lead formed a 

 precipitate ; a solution of the sulphate of iron 

 caused a green precipitate ; tartarised an- 

 timony had no effect, nor the nitrate of silver ; 

 gelatin produced no change ; alcohol formed 

 a precipitate ; muriate of tin formed a reddish 

 brown precipitate. 



EXPERIMENT IX. 



The solution of the resinous matter obtain- 

 ed from the leaves exhibited the following ap- 

 pearances : With the carbonate of potash it 

 formed a brown precipitate; with barytic wa- 

 ter an abundant precipitate was induced ; with 

 litmus no change was discernible ; the acetate 

 of lead caused an abundant yellowish white 

 precipitate ; with nitrate of lead a precipitate
