ALKALOIDS IN JAVANESE CINCHONA. 
Ho. 12. The top of a tree growing in the plantation Ivebon Pahud on the 
mountain Malabar, 5800 feet above the sea. The top had been broken off by 
the wind, but the tree is still alive. 
Ho. 13. A tree grown in the plantation Kebon Pahud on the mountain 
Malabar, 5800 feet above the sea. The amount of the bark of the stem of 
this tree was only 22 grammes, and that of the bark of the root only 8 grammes, 
so that both were combined for chemical investigation. 
ISTo. 14. A tree grown in the same locality. The root was so small that it 
produced only 4 grammes of bark, which were not analysed. 
P. Cinchona lanclfolia. 
Ho. 1. A tree four years old, grown in the plantation Gedongbadak on the 
mountain Malabar, 6200 feet above the sea, almost without shade. 
C. Cinchona jpahudiana. 
Ho. 1. A tree seven years old, transplanted four years ago from the bad 
volcanic subsoil at Tjibodas, in the dense forest on the slope of the moun¬ 
tain Gede, 4700 feet above the sea. Was sixteen feet high when it died. 
Ho. 2. Avery thin tree, seven years old, from the same locality. Although 
it was eighteen feet high, it produced only 148 grammes of dry bark. 
Ho. 3. A tree seven years old, grown in the open sunshine in a bad volcanic 
subsoil at Tjibodas, 4500 feet above the sea. Was in perfect health, and had 
borne abundance of flowers and ripe fruits. The circumference of the stem at 
the base w r as 25'5 centimetres. 
Ho. 4. A tree seven years and three-quarters old, grown and transplanted 
like Ho. 1. Its height was 356 centimetres, with a circumference at the base 
of 24‘5 centimetres. Was in perfect health. 
Ho. 5. A tree tw r o years and a quarter old, grown at Tjiniroean, on the 
mountain Malabar, 4820 feet above the sea, in the shade of the forest, from 
Javanese seed. The fibrous root produced 46 grammes of dried bark. 
Ho. 6. A tree five years old, grown in the plantation Gedongbadak, on the 
mountain Malabar, 6400 feet above the sea. It was 253 centimetres high, 
with a circumference at the base of 18 centimetres. 
Ho. 7. Six trees, four years old. The tallest was 342 and the shortest 234 
centimetres high. Only the roots of these very thin trees w^ere anatysed. 
Ho. 8. One hundred young trees two years and a half old, grown in dif¬ 
ferent localities on the mountain Malabar between 5000 and 6500 feet above 
the sea. These very healthy plants produced together 1670 grammes dry 
bark of the stem, 12966 grammes dry stemwoocl, 870 grammes dry bark of 
the roots, and 1911'54 grammes dry wood of the roots. 
Ho. 9. Pour thin trees four years old, grown in the plantation Gedongbadak, 
on the mountain Malabar, 6300 feet above the sea, from which the tallest was 
530 and the shortest 153 centimetres high. The roots were so small that they 
produced together only 56 grammes of dry bark. 
Ho. 10. A very healtlry tree four years and a half old, grown in the planta¬ 
tion Gedongbadak, on the mountain Malabar, 6200 feet above the sea, in the 
forest, but almost without shade. It was 500 centimetres high, with a cir¬ 
cumference at the base of 5’9 centimetres. 
Ho. 11. A few^ hundred very young seedlings between six and eight inches 
long, which had died shortly after their being planted out in the forest. Their 
roots produced 100 grammes of dry bark. 
Ho. 12. The top of a still living tree growing on the mountain Malabar, 
5900 feet above the sea. 
Ho. 13. Avery healthy tree, five years old, grown in the plantation Gedong¬
