LIX.—PHYTOCHEMICAL INVESTIGATIONS AT KEW, 
By the late Dr. M. GresHorr. 
Director of the Colonial Museum, Haarlem. 
In August, 1909, I had the privilege of examining phyto- 
chemically in the Jodrell laboratory at Kew a number of plants 
cultivated in the celebrated Royal Botanic Gardens, 
During this examination I received generous help from the 
Kew scientific staff; my indebtedness to them is here gratefully 
acknowledged 
In this report I wish to give a brief survey of my results ; at 
present only a part can be published, as it was found necessary to 
examine further many plants at another season of the year. I 
hope to do this in 1910, and then to bring together the additional 
results in a second report. 
At Kew there was a unique opportunity, not only of supple- 
menting and checking previous observations made in my own 
laboratory at Haarlem, but especially of investigating chemically 
plants which had not been analysed hitherto, and thus of collecting 
new data for pharmacology, toxicology, and in a wider sense, for 
comparative phytochemistry, i.e. the knowledge of the connection 
hip of plants and their chemical

The subject has always 
attracted me, and considerations connected with it have influenced 
me both in the laboratory and in theoretical study. Perhaps I 
may therefore be permitted once more briefly to point out what 
is the task of the chemist in a botanic garden, and especially what 
is the relation between his chemical work and botanical science, 
especially systematic botany. g .
