BOOK REVIEW. 
“Elementary Dietetics for the Student of Domestic 
Science and the Housewife.” By George Zephirin Dupain, 
Sydney, Geo. B. Philip & Son, 128 pp. Price, 2/- (school 
edition), 3/- (library edition). 
The author is an associate of the Australian Chemical 
Institute, and explains in an easy way some of the results 
of modern research into the value of different foods. In 
a diet which is well balanced, says the author, there will be 
found proportionate amounts of proteins, fats, carbo- 
hydrates, mineral salts, vitamins and water. He does not 
make the mistake of allowing himself to become obsessed 
by one factor, but looks at all constituents of food in their 
proper proportion. Directions are given for simple chemi- 
cal tests that can be carried out in the home, and these are 
followed by the relative values of the different methods of 
cooking and the best means of treating different foods. 
The book contains a lot of miscellaneous information, 
especially in the chemical side not usually obtainable in so 
codensed a space in a popular book and only usually 
obtainable by searching through many volumes and 
pamphlets. 
NOTES ON THE CRETACEOUS DEEP SEA DEPOSITS OF 
ENGLAND AND THE SHALLOW SEA DEPOSITS OF THE 
LIBYAN DESERT. 
By G. K. Jackson (on active service) 
To the average Queensland naturalist, geological deposits 
of the Cretaceous Age, the last age of the Mesozoic era, are a 
well-known and carefully studied feature of our State. The 
vast area of the artesian basin, known to geologists as the 
site of “The Great Cretaceous Sea of Queensland,” has always 
been, and always will be a vast encyclopedia of knowledge. 
In it we may turn back the pages of the past, and see life 
replaced by inorganic deposits in the petrified sea bed of another 
age. 
I chose the two areas under consideration not merely be- 
cause I have had the opportunity of studying both, but rather 
in view of the fact that they are so vastly different. Both
