Abstract
A SUGGESTION was recently made by Herr X Bealz that blue patches in the sacral region furnished a valuable test of race. Such marks are found among the children of Chinese, Koreans, Japanese, and Malays. Mr. Gait, Census Commissioner for India, directed that during the 1911 census inquiries should be made into the question. Much information on the subject will be found in Mr. C. M. Webb's Census Report of Burma for 1911, recently issued (vol. i., pp. 281 et seq.). The results are not decisive, and there are at present no means of giving statistics showing the prevalence of these marks. But they are found extensively in Burma, and seem to indicate the existence of a Mongoloid strain in the population.
