There are some observations which support the conclusion that the brain attains its greatest weight before 30 years of age, and then undergoes diminution. At the age of 80 this diminution is supposed to reach 10 per cent. The diminution concerns the brain proper and the cerebellum, but not their connecting part, the pons, which increases up to the fiftieth year. Whilst it is, however, difficult to imagine methods by which, without risk of great fallacy, such conclusions could be arrived at, we may safely believe that the advance of age is attended by some reduction in the size of the skull cavity and the weight of its contents. It appears to be a constant law that with advance of civilisation the differences between the sexes in general become increased. This is seen in measurements of the skull and in the weight of the brain. In the brains of negroes the woman is but little below that of the man, 984 to 1,000, but in the English it is only 860, and Germans 838. These figures indicate, of course, proportions only, and like all other calculations in this difficult subject, must be received with caution; but they probably indicate, if they do not precisely express, the fact. The height of the skull is usually in inverse ratio to its breadth. The variation in height is far less than is common in breadth. The brachycephalic have heavier brains than the dolichocephalic. In Hottentots both indices, breadth and height, are low. The following may be mentioned as examples of remarkably broad heads (wide foreheads), in association with genius: Shakespeare, Beranger, Mirabeau, Peacock (the novelist), Miss Austen, Blackmore (“Lorna Doone”), Tennyson, Erskine. The following had heads both tall and broad: Scott, Goethe, Cervantes, Ambrose Paré, John Foster, Father Paul, Galileo, Michael Angelo, Machiavelli, Benjamin West. We shall be indebted to any of our readers who may direct our attention to other well-marked examples. The following afford instances of remarkably tall heads: Motley (the historian of the Netherlands), Remin (engineer), Richard Roberts (engineer). The following had remarkably long faces: Francis I., Inigo Jones, George Eliot (Miss Evans), Savonorola. * * * * * THE EGG MARKET IN ENGLAND.
