The report of Mr. J. C. Hopkins on the Clays and Clay Industries of Western Pennsylvania is the second one of a series of economic reports on the natural resources of the State in course of publication by the Pennsylvania State College. The first report, published in 1897, was on the Brown Stones of Pennsylvania. The report represents that a capital of nearly $7,000,000 is invested in the clay industries about Pittsburg, of which more than $3,000,000 are in the fire-clay industry. The value of the annual output of material is nearly $4,000,000, more than fifty per cent of the capital invested. The 139 companies employ 4,403 men. Herr Hansemann, of the University of Berlin, who examined the skull of Helmholtz, reports in the _Zeitschrift für Psychologie_ that he found the head about the size of Bismarck's, and a little smaller than Wagner's. By metrical standards the brain weighed about 1,700 grammes with the coagulated blood, and about 1,440 grammes without it--about 100 grammes more than the average. The circumvolutions, which are now thought to have more relation to mental capacity than mere weight, were particularly deep and well marked. The skull was 55 centimetres in circumference, 15.5 centimetres broad, and 18.3 centimetres long, and the cephalic index was 85.25.
