Abstract
A COURSE of four Cantor Lectures delivered before the Society of Arts by Mr. Bennett H. Brough, on the nature and yield of metalliferous deposits, has just been published Descriptions are given of the principal ore deposits of the world and the statistics of production appended furnish a clear idea of the condition of the mining industry at the present time. The subject is of great importance from a commercial point of view, as will be evident from a moment's consideration of the enormous value of mineral resources. In the United Kingdom alone, the value of the minerals raised in one year has approached 80,000,000l.; and the vast sums representing the British capital nvested in mines in all parts of the world will be readily appreciated. Last year, the number of new mining companies egistered in Great Britain was 559, with a united nominal:apital of 71,687,366l. Of these companies, 281, with a nominal capital of 37,037,057l., were formed to mine and explore in British colonies and dependencies, and 157, with a nominal capital of 24,049,502l., to mine in foreign countries. During he present century the mining industry has made remarkable strides. Some indication of the progress made, even during the last ten years, is afforded by a comparison of the world's output of metals in 1889 and in 1898. In round numbers, the production of the principal metals was as follows:—
