INDUSTRIAL FATIGUE. 
The first annual report of the Industrial Fatigue Research Board. 
(H.M. Stationery Office) contains an interesting record of work com- 
pleted or in progress. Of the four reports already issued, that of Dr. 
Vernon, dealing with the influence of hours of work and ventilation on 
output in the tin-plate industry, is the most extensive, while the report 
by Mr. Major Greenwood and Miss Hilda Woods, upon the incidence 
of industrial accidents (the statistical theory of this investigation has 
been further developed in a. paper by Messrs. Greenwood and Yule, 
published in March, 1920, issue of the Journal of the Royal Statistical 
Society) suggested some important problems which the Board proposes 
to study further. Mrs. Osborne’s paper on the output of female muni- 
‘tion workers, and Dr. C. S. Myer’s analysis of the results obtained in a 
factory after the introduction of motion study, are also of interest. 
Amongst investigations not yet completed, that on the relation between 
length of shift and fatigue in the iron and steel industry, intrusted 
to Dr. H. M. Vernon, is almost ready for publication, and progress has 
been made with inquiries into special conditions affecting the cotton, 
boot and shoe, and silk industries. The Board has a large number of 
tasks in hand, and it is yet too early to decide which are likely to be 
most remunerative. It is, however, clear that careful thought has been 
devoted to the organization of research, and we have no doubt that the 
outcome will be of the greatest benefit to both employers and employed.

SANDALWOOD. OIL. 
The sandalwood industry in Western Australia forms the subject 
of a note in a recent issue of the 7’zmes Trade Supplement. It is much 
to be regretted that, in season and out of season, attempts are made to 
persuade those who do not know to the contrary that the difference 
between the true sandalwood oil of the British Pharmacopwia and 
the Western Australian oil of the same name is merely an academic 
one. In the note in question it is stated that one species of Santalum 
growing in the State has yielded an oil similar in most respects to 
Mysore oil, but with an average rotation of 2 degrees. Investigation, it 
is claimed, has, at all events, shown that the lowest quality of refined 
Western Australian cil is equal, medicinally and therapeutically, to the 
Mysore oil. This claim, it is suggested, cannot be substantiated, and 
would mean that 70 per cent. of the alcohol, whatever it 
may be, present in Western Australian oil is as active, medici- 
nally, as 90 per cent. or more of true santalol present in 
the Indian oil. The real facts are, it is stated, as ‘follows: 
—The Western Australian oil is distilled from a _ species of 
Santalum which yields a quite different oil from’ that of Santalum
