[August i, 1884, 



mutual action of gratt and under-steui. The analyses of 

 the hark of those trees produced from grafts of 89 and 

 23, however, remove this fear. In neither was a trace 

 of cinchonidme met with. The presence of this alkaloid 

 therefore in 3 and 4 must he explained by the fact, that 

 in these cases grafts from cinchonidine-yielding mother 

 trees had been used. In future grafts will he taken only 

 from trees in whose bark there is no cinchouidiue, and 

 preferably from the tree 23, of which there is already 

 a large planting, and the seed of which gives a constant 

 supply of plants distinguished hy a very high quinine yield. 

 By the an^lysis of officinalis bark it was once more proved 

 that the root bark of this variety is very rich in quinine. 

 The analysis 02 is of the bark of a tree grown at. 

 Lembang, about 14 years old, which had developed slowly, 

 the alkaloid yield is however very high. A typical C. 

 officinalis, tar. angustifolia, analysis 63, also once more de- 

 monstrated the high quinine yield which, in the case of 

 this variety, Broughtou was the first to discover. The 

 one year old renewed bark of the officinalis hybrid, ana- 

 lysis 64, which in its original bark contained 10 per cent 

 of alkaloid, of which 2 per cent was quinine and 6'9 per 

 cent cinchonidme, now gave 2-8 per cent quinine and l'S 

 per cent cinchouidine. The hark of the C. eorclifolia trees 

 at Rioen Ooenoeng, grown at 5,800 Rhenish feet, contained 

 an amount of quinine which was notably higher than what 

 has hitherto been met with in bark of this variety.
