SCIENCE AND INDUSTRY. 
_ disinfectants, enamelling, essences and extracts, etching, food adulterants, 
glass, hair preparations, inks, lubricants, milk, oils, perfumes, photo- 
graphy, plating, polishes, salts, soaps, solders, steel, varnishes, veterinary 
formule, waterproofing, wines and liqueurs, wood, and yeast. 
All the formule and recipes are culled from standard reference 
works, such as pharmacopie and technological works, and in outlining 
various processes well-known authorities are quoted. Mr. Hiscox, how- 
ever, advises, in a prefatory note, that each recipe is to be regarded as 
a basis of experiment, to be modified to suit the particular purpose in 
hand, or the peculiar conditions which may affect the experimented. 
Chemicals are rarely of uniform relative purity and strength; heat or 
cold may markedly influence the result obtained, and lack of skill in the 
handling of utensils and instruments may often cause failure. These 
points must be borne in mind. Inasmuch as a particular formula may 
not always be applicable, several are given from which a_ suitable 
selection may be made. One at least should answer the purpose. 
WHAT INDUSTRY OWES TO CHEMICAL SCIENCE. 
A series of articles contributed to The Engineer in 1916-17 by Messrs. 
R. B. Pitcher and F. Butler-Jones has lately been published in book 
form under the title* What Industry owes to Chemical Science. In an 
introduction to the little volume, Sir George Beilby points out that the 
records compiled by the authors supply a complete answer to the very 
common questions—what is the place of the chemist in practical life, 
and what part has he taken in industrial and social development? It. 
is a graceful appreciation of labour which is conducted in the back- 
ground, “ inobvious, and little, if at all, understood.” 
The purpose of the articles was to show by concrete examples how 
science has advanced the methods and processes of production, and 
has laid the foundation for the establishment of new manufactures. 
The authors haye, therefore, set forth, without any effort at literary 
embellishment, the broad facts of achievement. Should these facts in 
themselves fail to interest, the reader will derive no other pleasure from. 
the book. As Sir George Beilby points out, “the precious stones in 
the necklace have been strung together rather with an eye to their 
collective preservation than to their artistic effect as a whole.” Almost 
the whole range of production has been covered, the subjects having 
been grouped under nineteen headings. The volume contains much that 
is of value to the teacher and to the student. It should also appeal to 
a large section of the public. :
