A Case of Cæsarean Section in Multiple Pregnancy *Read 11th January 1922.

Inversion of the Uterus, with a Record of Four Cases *Read 11th January 1922.

Case I. (Puerperal).?Mrs P., primipara, net. 31, was confined on 23rd March 1906. The labour was uneventful. Low forceps were applied for persistent O.P. The placenta came away easily in twenty minutes, there was one stitch in the perineum, and there was no haemorrhage. She did not suckle her child. She was kept in bed for a fortnight, and resumed her usual duties at the end of the third week f...

Global Tectonic Regionalization for Seismological Data Analysis

A global tectonic regionalization, GTR1, has been constructed for use in seismological studies of aspherical heterogeneity. Three oceanic regions are defined by equal increments in the square root of crustal age (25and lO0-m.y. isochrons), and three continental regions are distinguished according to their generalized tectonic behavior during the Phanerozoic (Precambrian shields and platforms, P...
