It will be noted that manganese is generally present in C. cinerar¬ 
iaefolium from Dalmatia in both stems and “open” flowers to an equal 
amount, and to a slightly greater extent in the “closed” flowers. The 
analyses of samples from Japan showed that manganese is always present 
and in larger amount than in the Dalmatian samples. This is to be 
expected, because the soils of Japan are largely of volcanic origin and are 
known -to contain large amounts of manganese. Stems of Japanese 
origin contain about three-fourths as much manganese as do the “closed” 
flowers from that country. “Open” flowers are not at present exported 
from Japan, so the writers have no available data on this product. The 
sample of buhach from California contains manganese. In fact, it is 
doubtful if any sample of insect powder is free from it. 
The relation between the manganese, nitrogen, and phosphoric-acid 
content of stems and flowers of different degrees of maturity and different 
origin is brought out in Table II.
