of Latitude and Longitude in different Latitudes — Tables of formula 

 for Astronomical observations, and especially for determination of 

 Time, Latitude and Longitude. Such a number of useful tables and 

 formulas — and we have given but a partial enumeration of them — have 

 never before been brought together in the same compass. Moreover 

 we cannot commend too highly the clear typography of the volume, 

 and the perspicuity of its arrangement, nor the apparent care and labor 

 with which the work has been prepared by Captain Lee. 



11. Description of a System of Military Bridges with India Rubber 

 Pontons, prepared for the use of the United Slates Army; by Capt, 

 George W. Cullum, U. S. Corps of Engineers. — Paper No. 4, from 

 Papers on Practical Engineering, published by the Engineer Depart- 

 ment, for the use of the Officers of the United States Corps of Engi- 

 neers, pp. 274 to 414 and plates 18 to 22 inclusive. The valuable 

 memoir whose title is here cited, is illustrated by full details, giving all 

 the particulars required in the construction of Bridges with India Kub- 

 ber Pontons. 



12. Transactions of the Neiv York State Agricultural Society, with 

 an abstract of the proceedings of the County Agricultural Societies. 

 Vol. viii. 1848. Albany. 1849. 8vo., pp. 975.— The able and indus- 

 trious secretary of the State Society, has placed this huge volume in 

 our hands. Its contents are various, but important and interesting 

 worthy of the state from whose public assembly this volume issues as 

 a part of their legislative proceedings. Mr. Salisbury's memoir on the 

 chemical constitution of Indian corn, forms a part of this volume. The 

 addresses and proceedings of the Society and the agricultural returns 

 of the several counties of the state, agricultural discussions on various 

 topics by the members of the State Society, occupy a large part of the 

 volume, which is concluded by an agricultural survey of Washington 

 county, by Dr. Asa Fitch. Among the most important matters dis- 

 cussed in this volume is the subject of a Normal Agricultural School, 

 to be established by the State government, for the proper promotion of 

 agricultural education and research. This is a subject of commanding 



importance, and it behooves the state of New York to set a liberal and 



enlightened example in this respect. 



13. History and Chemical Investigation of Maize, or Indian Corn; 

 b y J. B. Salisbury. Albany. 1849.— This research is a " Prize Es- 

 say " to which the New York State Agricultural Society have awarded 

 ^eir premium of $200, offered two years ago. This " Essay" forms 

 Part of the valuable volume of Transactions of the Society for this year, 

 Just published as above noticed. 



Mr. Salisbury's research is very elaborate and extended. It is em- 

 bodied in 206 octavo pages, a large part of which is taken up with 

 closely printed tables of analytical results, and of calculations deduced 

 from them. We have received this essay at the moment of going to 



Press, and have had no opportunity to make a critical examination of 

 Mr. Salisbury's methods or results. We have however, seen enough 

 to know that great labor has been bestowed on this research, and that 

 toe author's attention has been devoted to a wide range of inquiry in 

 reference to the chemical constitution of all parts of this great Ameri- 

 can staple grain, and of the soils and manures upon which it has been
