 cite Coal-Trade of Pennsylvania, with 

 Statistical Tables, etc. By the Messrs. 

 Sheafer, Engineers of Mines, Pottsville, 

 Pa. Chart. 



This diagram is designed to accompany 

 a paper which was read before the Ameri- 

 can Association for the Advancement of 

 Science, at its meeting for 1879. It shows 

 the gradual development of the trade, and 

 the dates of the opening of new avenues to 

 the market. An accompanying diagram 

 shows the estimated quantity of anthracite 

 coal in the three several coal-fields of Penn- 

 sylvania, and the relative amount of waste 

 and quantity mined. Another cut repre- 

 sents a cross-section in the southern anthra- 

 cite coal-field of Pennsylvania. The tables 

 show a variety of facts bearing on the sub- 

 ject, in Pennsylvania, the United States, and 

 the world.

These primers are prepared for the pur- 

 pose of diffusing as widely and cheaply as 

 possible a knowledge of the elementary 

 facts of preventive medicine and the bear- 

 ings and applications of the latest and best 

 researches in medical and hygienic science, 

 and of teaching people how to take care of 

 themselves, their children, etc. They are 

 written from an American point of view, 

 with especial reference to our climate, sani- 

 tary legislation, and modes of life. The 

 whole series is under the general supervision 

 of Dr. W. W. Keen. The first volume, whose 

 title is given above, considers each of the 

 common special diseases of summer, and 

 the means of preventing and curing them, 

 and has a chapter on the skin in summer 

 and its maladies. The second work enforces 

 the need of suitable clothing, care in bath- 

 ing, ample provision of pure fresh air, and 

 out-of-door exercise in winter. In the third 

 volume, the structure, care, and several dis- 

 eases of the throat are treated of in sepa- 



rate chapters, and a second part is devoted 

 to the voice and its cultivation. In the last 

 primer of the list are discussed the sub- 

 jects of the " Causes of Nervous Trouble," 

 " Work," " Rest in Labor," " Rest in Recre- 

 ation " and " Rest in Sleep." 



Memoirs of the Science Department, Uni- 

 versity of Tokio, Japan. Vol. II. On 

 Mining and Mines in Japan. By C. 

 Netto, M. E., Professor of Miniug and 

 Metallurgy, University of Tokio. Pub- 

 lished bv the University, Tokio. 2539 

 (1879). "Pp. 56, with Plates. 



This work comprises the substance of a 

 lecture which was delivered before a German 

 society, and has been translated into English 

 to make it more accessible to Japanese stu- 

 dents. The useful minerals in Japan, ranked 

 nearly according to their importance, are 

 coal, copper, silver, gold, iron, kaolin, petro- 

 leum, sulphur, lead, antimony, tin, cobalt, 

 quicksilver, marble, jasper, agate, amber, 

 graphite. The processes of mining and re- 

 ducing the ores are described, after which 

 is given a summary of the Japanese mining 

 law, and a review of the measures that have 

 been adopted or are contemplated by the 

 Government for the encouragement of min- 

 ing. Modern methods are shown to have 

 been adopted in several of the mines, and 

 their introduction has been attended with 

 increase of production. The Government at 

 present carries on a number of mines, into 

 which it has introduced modern model works, 

 partly for the sake of setting a good exam- 

 ple to private owners. It is its policy, how- 

 ever, to surrender its establishments when 

 they have become well organized, to be 

 worked by private citizens. Six large plates 

 give representations of the tools used by the 

 Japanese in mining.
