THE last half-yearly number of the Journal of the Royal Anthropological Institute contains an important memoir, prepared by two enthusiastic Scotch anthropologists, Messrs. Gray and Tocher, on the pigmentation of hair and eyes among the school children of Scotland. In one respect the methods employed fail to secure that precision which is necessary to an investigation of this kind. Attempts were made to furnish the correspondents with standard colour cards produced by the three-colour lithographic process, but English manufacturers have up to the present been unable to provide them. There seems, however, to be a prospect of overcoming this difficulty by the adaptation of Lovibond's tintometer to anthropological work. The new instrument is described by Mr. Gray in the April number of Man.
