V.—Notes on Some Rocks from Ababia Petræa

Extract

Professor Hull, soon after his return from Palestine, was good enough to place in my hands, for microscopic examination, a collection of twenty sections of rocks prepared from specimens obtained in the course of his expedition. Subsequently I had the advantage of receiving thirteen small specimens of the rocks from which some of the sections had been cut; and respecting these rocks some lithological notes have been published as an appendix to Prof. Hull's Memoir. At a later date I received seven other rockspecimens, representing the remaining sections in my charge; but for want of time these were laid aside unexamined until it was too late to refer to them in the published work. The object of the present notes is therefore to offer brief descriptions of these remaining rocks. At the same time I gladly seize this opportunity of correcting some errors which unfortunately crept into the previous descriptions.
