The constantly increasing demands upon the Garden for in- 
formation upon the chemical composition of plant products, and 
the investigations undertaken by the Garden in which chemical 
methods and analyses are required has made necessary the be- 
ginning of the equipment of the chemical laboratories. 
This development will be carried out under the advice of Dr. 
Wm. J. Gies, who has recently been appointed Consulting Chem- 
ist to the Garden. Dr. Gies at present holds the position of ad- 
junct professor of physiological chemistry in Columbia Univer- 
sity, and his extensive epencnce in investigation and in the work 
with the institution in several important things, having directed 
Professor Kirkwood’s studies of the chemical changes in ger- 
minating cocoanuts, now in press, and with Professor Kirkwood 
furnished the text for the section of Dr. MacDougal’s text-book 
of plant physiology, dealing with the composition of plants.
