units. Direct current may be supplied by 
batteries or by an a.c.-d.c. converter. 
Refrigeration in the laboratory consists of 
a deep-freeze unit, a 150-cubic foot reefer box, 
and electric household-type refrigerators. 
Small stocks of routine glassware and re- 
agents are maintained at the laboratory. Cer- 
tain equipment such as pW meters, colori- 
meters, Warburg-Barcroft apparatus, Van- 
Slyke apparatus, cathode ray oscilloscope, and 
other physiological equipment, microscopes, 
microtomes, balances, cameras, and virtually 
any other needed item will be supplied by the 
University from its main campus when the 
need for them arises. All investigators, how- 
ever, are requested to submit a detailed list of 
their needs so that they may be advised of 
what the Laboratory is in a position to supply. 
Field equipment: The opportunities for in- 
vestigators to conduct research in the field 
and to observe marine species in their natural 
environment constitute one of the chief at- 
tractions of the Laboratory, and every effort 
is made to assist investigators on projects re- 
quiring this type of approach. 
The field equipment includes the 46-foot 
research vessel, the Salpa (Fig. 6), which has 
a live well with circulating sea water and 
hoisting gear for dredging, hauling plankton 
nets, and hydrographic work. Gear such as 
dredges, seines, and nets of various sorts, 
traps, plankton nets from small to meter-size

Openings, Clarke-Bumpus and high-speed 
quantitative plankton nets, current meters, 
Nansen bottles with reversing thermometers, 
bathythermographs, glass-bottom boxes, and 
diving equipment is available. As with labora- 
tory supplies, investigators are advised to in- 
quire in advance as to their particular re- 
quirements. 
In cooperation with the Territorial Division 
of Fish and Game and the Pacific Oceanic 
Fishery Investigations, larger vessels for work 
at sea and for deeper dredging are often avail- 
able to qualified investigators. Such coopera- 
tion must be arranged for well in advance. 
Library facilities and publications: The prox- 
imity of the extensive libraries of the Univer- 
sity of Flawaii, Bernice P. Bishop Museum, 
Hawaiian Sugar Planters’ Association Experi- 
ment Station, Pineapple Research Institute, 
and the Pacific Oceanic Fishery Investigations 
make it unnecessary to maintain a separate 
library at the Laboratory. At these libraries 
investigators may secure reference material 
needed for use at Coconut Island. Microfilm 
readers are available at the University Library. 
The Hawaii Marine Laboratory issues two 
series of publications. The "Contributions 
from the Hawaii Marine Laboratory" are 
technical papers published in suitable journals 
and are numbered serially. Papers in this 
series are available to individuals in the fields 
of their interest, and to institutions which may 
request individual or all papers of the series. 
Exchanges are desired. A second series of 
mimeographed leaflets, entitled "Hawaii
