appear. The Census Report contained Dr. Hutton's contribu-
tion to caste. The anthropometric survey when published,
created a little confusion in the beginning. Later on its grave
defects were pointed out by me.

My book, as extracts of some of the reviews so insistently
printed by the present publishers will show, was almost uni-
versally well received. It went out of print some years back,
when owing to other pre-occupations I could not direct imme-
diate attention to its revision. When I was almost free to do
so I found that Dr. Hutton had forestalled me with his book
Caste in India. Naturally I waited for some time.

During the interval of nearly twenty years from the time
when the manuscript of Caste and Race in India was ready
and the actual revision of it, the subject of caste as an
extreme case of social stratification has assumed a significance
which was realized by me but was not common heritage of
sociologists. The European institution of class, too, has come
in for a more detailed and analytical treatment. A number
of investigations to measure its strength, to unravel its precise
nature, were made, more in the U.S.A. than in the U.K. The
Marxian doctrine of class-war, since the success of the Rus-
sian Revolution and the establishment of the Soviet Regime,
turned the attention of not only professional students but
wise statesmen to the understanding of class structure. In
the United States the Negro problem worried and worries a
number of sociologists and statesmen. Its apparent affiliation
to caste has naturally turned American attention to the study
of caste. Racial differentiation brought to the forefront by
the Nazis in Germany further oriented the subject. The
result is seen in the much fuller treatment of class and caste
in the recent edition of the best of English text-books of Socio-
logy, Prof. R. M. MacIver Society, which he has brought out
in collaboration with Page. A little earlier Cox wrote a
whole volume, which for the first time brought the three
aspect of social differentiation, caste, class and race, together
under one title.
