192 Galton. Professor Pearson sent circulars to a large number of teachers asking them to grade pairs of brothers and sisters for mental and moral traits, such as popularity, conscientiousness, probity, vivacity and general ability. There proved to be a remarkable fraternal resemblance, represented by a regression line of one to two, exactly the same as that found for physical traits such as the cephalic index. Professor Pearson concludes that mental and physical heredity are equally potent; mental traits are bred in the bone and are not the result of training. Great Britain could not help its position among the nations by improving its schools or by increasing technical education. The trouble is that the less able and the less energetic are more fertile than the better stocks.

Professor Pearson's figures require confirmation. The writer of this note once remarked on the resemblance of some children to their mother; the resemblance became less obvious when he was informed that she was their stepmother. The fact that two children are brothers may lead a teacher to regard them as similar in mental traits. But Professor Pearson's figures in any case appear to be misinterpreted. If the resemblance of brothers in physical and mental traits is alike, we must conclude, contrary to Professor Pearson, that the inheritance of physical and mental traits is not equal. Association and similar home life have some influence, however slight, on traits such as temper and honesty. It would be possible to argue from the figures that mental traits are not hereditary, the effects of similar environment being equal in amount to physical heredity.

American Association for the Advancement of Science with a large number of affiliated societies, including the American Society of Naturalists, The American Chemical Society, The American Physical Society, The Astronomical and Astrophysical Society of America, the Botanical Society of America, The American Anthropological Association, The American Psychological Association and others, meet at St. Louis in convocation week, beginning on December 28. We shall give in the next issue a forecast of the meeting, at present only calling attention to the importance of this meeting and to the admirable arrangements that have been made and urging the privilege and importance of attendance, both for professional scientific men and for those who are interested in the progress of science.

Lawrence Scientific School of Harvard University will receive a very large sum, said to be more than $4,000,000, from the estate of the late Gordon McKay.

, of Cornell University, has proposed the erection of a new building for Sibley College, in memory of the late Professor Thurston, to be known as Thurston Hall. The students of Sibley College have voted to erect a bronze memorial tablet in honor of Professor Thurston. — An obelisk of unpolished grey granite has been placed over Virchow's grave in the old Matthäi graveyard, Berlin. It bears on one side a black marble tablet, on which is inscribed 'Rudolf Virchow' and the date of his birth and death. A statue of Virchow will also be erected near the place where his scientific work was conducted.
