The problems of the Sudbury irruptive are approached here mainly from two points of view: (1) the nature of the zone intermediate to the acid and basic portions and (2) the place of these rocks in the general Keweenawan petrographic province of Ontar

The Gaston rebound tester is used to determine the relative elasticities of various minerals. Under this test fluorite, pyrite, quartz, and garnet are shown to be more elastic than steel. The remarkable rebound of 97 per cent was obtained on garnet,

A method is presented which to a large extent eliminates the errors of observation of the optic axial angle by the Michel-Levy method. Instead of standardizing circles of reference, observations on a mineral of known 2E are made directly through the

A series of observations, both of the field relations and of the microstructure of this nickel ore-body, are recorded. The igneous theory of the origin of the deposits is brought into question and a hydrothermal view of the genesis put forward.

The crystallization of a hydrous melt in the system K2SiO3—SiO2—H2O is studied in detail to determine what are the external factors exerting the greatest influence over the character of the final crystallization product. These are found to be (a)

In this paper the article by Mr. G. W. Bain on the "Amount of Assimilation by the Sudbury Norite Sheet" is criticized and certain fallacies in the argument are pointed out. A comparison is made with the Arnage norite of Aberdeenshire, which provides

A microscopic examination of the linings of a copper converter and of a lead blast furnace is described with a view to deducing criteria for the discrimination between the formation of sulphides by anhydrous melts and by hydrothermal agencies.

In the Abstract of his paper on the "Evidence of Assimilation and Assimilation Processes" Mr. Bain states that he is here dealing with the general process of assimilation. His paper itself, however, treats in considerable detail of the Sudbury "norit
