search. Three of these are by F. H. Storer, 

 Professor of Agricultural Chemistry, and are 

 of direct and practical value. One is a 

 "Eecord of Trials of Various Fertilizers 

 upon the Plain-field of Bussey Institution," 

 another is a "Report on some Analyses of 

 Salt- Marsh Ilay and Bog-Hay," and the third 

 one is on the "Fodder Value of Apples." 

 In this last one Prof. Storer says that, while 

 apples contain a very small percentage of 

 nitrogenous matter, they are not to be over- 

 looked as a food for cattle and swine, and 

 should be used with peas, beans, oil-cake, 

 or other highly-nitrogenized food. 



An able article is contributed by Prof. 

 Farlow on "Potato Rot," which is illus- 

 trated, and one by Prof. Slade on " The Im- 

 portance of the Study of Applied Zoology 

 to the Practical Agriculturist." 



Second Gkological Survey op Pennsyl- 

 vania, 1874. Preliminary Report on 

 the Mineralogy of Pennsylvania. By F. 

 A. Genth. With an Appendix on the 

 Hydrocarbon Compounds, by Samdel 

 P. Sadtler. Harrisburg : Published by 

 the Board of Commissioners for the 

 Second Geological Survey, 18Y5. 



This report by Prof. Genth, to be 

 followed by a thorough work on the min- 

 eralogy of the State, is an excellent hand- 

 book of the minerals of Pennsylvania, and 

 of their localities. Most of the minerals of 

 the State are fully and clearly described, 

 and their analyses, many of which are new, 

 are given. The system of classification 

 adopted is that of Prof Dana, and the 

 report, although submitted as a preliminary 

 one, is indispensable to every student of the 

 mineralogy of Pennsylvania. The report 

 contains a topographical map of the State, 

 and its general thoroughness is shown in its 

 elaborate index.
