In all the maps the English measurements are given, and in each 

 case their metric equivalents — the pity of it, that we need to record in 

 two systems ! 



It almost seems like caviling to offer any criticism on so sumptuous 

 a work. But there are some shortcomings. In only one case is the 

 projection used named ; it would have been an agreeable addition, 

 had the projection been specified for all maps of lesser area, and in all 

 such maps a horizontal scale should be given, either in arithmetical 

 ratio, or by linear representation of miles and kilometers. There is 

 scarcely a scale in the book. 



In all maps of isohyets the very important element of altitude, it would 

 seem, is almost a necessity for the proper interpretation of the rainfall, 

 vet on Plate XXI, the principal plate of isohyets, there is no attempt 

 to show altitudes., even in the larger areas of Europe and the United 

 States. The lack of contours and the scale in such insets as Jamaica, 

 Japan, Java, and Mauritius is a serious fault. Even in Plate XXIV in 

 the large scale map of isobars and isohyets of the United States and 

 Canada, only the one contour of 3000 feet is shown. Here, far more 

 than in the general maps of Plates I and II, are the several contours 

 needed. It may be, of course, that in some*cases, for example, the 

 India map, the relief was omitted to prevent overloading. And true 

 it is, that with all the mass of data entered in these maps, there is 

 never in any of them a lack of legibility. 



But after all the flaws are found, they are not very serious, they 

 are mere spots on the sun. The work will long stand as a monument 

 to very high ability in meteorology and cartography. — J. Paul G. 



Mineral Resources of Kansas, 1899. By Erasmus Haworth, 

 Univ. Geol. Surv. of Kansas, Lawrence, May 1900; pp. 67, 

 4 plates. 

 This is the third of the annual bulletins on the mineral resources 

 of the state which the University Geological Survey of Kansas is issu- 

 ing, and is worthy of note as a laudable effort on the part of an edu- 

 cational institution of high grade to convey to the people, without 

 distinction and without charge, commercially valuable information 

 gathered under scientific auspices. Is is one of the many current indi- 

 cations of the breaking down of the narrow limitations that have so 

 long hedged in the traditional institution of learning to its infinite
