Pacific Entomology 
Report of the Standing Committee Chairman 
J. J. H. Szent-Ivany 
This volume is a survey of the extraordinary progress made in the study of 
insects of the Pacific area between 1958 and 1961, based on reports by Standing 
Committee members and published articles. 
The possibilities of the spread of harmful or potentially harmful insects have 
been greatly increased by recent rapid expansion of swift communication facilities. 
As a result of introduced pests and methods used to control them, the balance of 
nature has in some areas been seriously disturbed. 
The author not only treats thirty-seven countries and island groups in consid- 
erable detail, but gives a comprehensive picture of the entomological status in the 
area as a whole as he takes the reader on an orderly tour clockwise around the 
Pacific rim from Alaska to Japan. 
Dr. Szent-Ivany is senior entomologist in the Department of Agriculture, Stock 
and Fisheries of the Territory of Papua and New Guinea.

Physical Aspects of Light in the Sea 
A Symposium 
John E. Tyler, editor 
A dozen authorities from France, Japan, Sweden, and the United States describe 
and demonstrate, through detailed text and copious illustrations, techniques useful 
in the physical aspects of marine or fresh-water research. 
Described and illustrated with photographs, diagrams, charts, and detailed con- 
struction plans are an underwater observation vessel and its photographic equip- 
ment; apparatus for measuring water samples and determining turbidity; instruments 
for photography in the sea and for measuring the angular distribution of submarine 
daylight. 
In addition to the practical aspects of submarine light, theoretical calculations 
for light fields and for the scattering function of small particles are provided.
