four-chamber incubator, built especially for physiological 
work, glass incubators for growing alge, a D’Arsonval gal- 
vanometer and much smaller apparatus. Furthermore, facil- 
ities for the development of the physiological-chemical side 
of the work are being rapidly increased, and these include 
apparatus for enzyme and general fermentation studies, in- 
cluding a Hill pressure filter for extracting plant juices, a 
nitrogen still, gas furnace, balances, the necessary glassware 
and chemicals, as well as other general facilities required. 
An effective water still with a capacity of seven gallons an 
hour has also been installed. 
The abundance of material in the Garden and greenhouses 
offers special opportunities for the solution of diverse botan- 
ical problems. Greenhouses are also maintained for the ex- 
perimental work, but houses especially adapted to the needs 
of experimental physiology and pathology constitute the 
next important material advance in the development of the 
research equipment. There is very close contact between all 
phases of garden endeavor; especially is a spirit of complete 
co-operation expected to prevail between the Garden work 
proper and research and instruction. : 
Investigation and Reports.—Besides the regular staff, the

Aside from the important work in the taxonomy of the 
flowering plants now in progress, some of the problems which 
are being investigated in the laboratories are the following:
