The records of travellers provide certain information which helps us to form reliable though limited conclusions as to the results of the +interbreeding of different human races+. Mrs. Rose Haig Thomas, to whom we are indebted for the exhibit of a photograph, taken during a journey through Spain a few years ago, of a Spanish gipsy woman with her three children, has made several observations of some interest. She became acquainted with a family in which "the mother was a dark-skinned, black-haired, black-eyed gipsy woman. (See photograph, Exhibit No. K 3.) The husband was a Spaniard with blue eyes. There were three children. Of these, the eldest had flaxen hair and blue eyes. The second was a boy with black eyes, black hair, and an olive skin as dark as the mother's. The third child was too young to justify any conclusion being based on its characteristics. It was only 18 months old; but was flaxen-haired, blue-eyed, and fair skinned." This observation of Mrs. Haig Thomas, in Granada, affords then a clear example of the segregation of blue-eye and flaxen-hair characters among the gametes of the black-eyed, black-haired, and olive-complexioned mother. For, in the light of Mendelian researches, it is obvious she was carrying these characters recessive, and that some of her gametes were pure in respect of them. ARAB _v._ SPANIARD. [Sidenote: K 4] The second photograph, exhibited by Mrs. Haig Thomas (Exhibit No. K 4), is of three sisters who were also photographed in Granada. The eldest is of the dark, typical "Arab type," so well recognised by Spaniards wherever it is seen in Spain. The second sister is clearly much lighter in hair and fairer in complexion than her sister. The nose, too, is very distinct in both. The baby is fair. It is impossible, of course, to trace the remote ancestry of these sisters, and Mrs. Haig Thomas obtained no information as to their parents, but from what we know of Spanish history the case suggests a +possible segregation of Moorish from Gothic features+ after the intermixture of the two races, by marriage, had occurred. But the question is extremely complex. It is impossible to say to what extent the inhabitants of modern Spain represent in varying degrees a commingled race of Phoenicians and Iberians, of these with Romans and Goths, and of all with Moors, themselves at the time of the conquest of Spain a mixed race. All that can be said with any degree of probability is that these various races have more or less intermingled[E] during the long history of Spain, and that the flaxen hair and blue eyes among its inhabitants are the heritage which the Goths have left them. [Footnote E: I advisedly use the word intermingled and not blended.] EUROPEAN _v._ AMERICAN RED INDIAN. For the facts of the segregation of European and Indian eye-colour, I am indebted to two friends who resided for many years in different parts of Canada, and who do not desire their names published.
