WHITLOCK'S GEOMETRY AND SURVEYING, is a work for ad- 

 vanced students, possessing the highest claims upon the attention of Mathematical 

 Teachers. $1 50. 

 In comparison with other works of the kind, it presents the following advantages : 



1 . A better connected and more progressive method of geometrizing, calculated to 

 enable the student to go alone. 



2. A fuller, more varied, and available practice, by the introduction of more than 

 four hundred exercises, arithmetical, demonstrative, and algebraical, so chosen as to 

 be serviceable rather than amusing, and so arranged as greatly to aid in the acquisi- 

 tion of the theory. 



3. The bringing together of such a body of geometrical knowledge, theoretical and 

 practical, as every individual on entering into active life demands. 



4. A system of surveying ivhich saves two-thirds of the labor required by the ordi- 

 nary process. 



This work is well spoken of universally, and is already in use in some of the best 

 institutions of this country. It is recommended by Prof. Pierce, of Cambridge, Prof. 

 Smith, of Middletown, Prof. Dodd, of Lexington, and many other eminent mathe- 

 maticians. 



From E. M. MORSE, ESQ. 



I consider that I have obtained more mathematical knowledge from Whitlock's 

 Geometry than from all other text -books combined. Unlike too many treatises of a 

 similar nature, it is eminently calculated to make mathematicians.

These books are believed to be unrivaled in the following particulars : 



1. The philosophical accurateness with which their topics are arranged, so as to 

 show the mutual dependence and relationship of their subjects. 



2. The scientific correctness and practical convenience of their greatly improved 

 nomenclature. 



3. The clear and concise manner in which principles are stated and explanations 

 are given. 



4. Brevity and completeness of rules. 



5. The distinctness with which the true connection between Arithmetic and its 

 cognate branches is developed. 



6. The excellent and thorough intellectual discipline superinduced. 



RECOMMENDATIONS. 



From R. T. P. ALLEN, Superintendent of Kentucky Military Institute. 

 Upon a careful examination of a manuscript Treatise on Arithmetic, by Prof. 

 Dodd, I find it greatly superior to all others which have come under my notice, in 

 system, completeness, and nomenclature. The arrangement is natural, the system 

 complete, and the nomenclature greatly improved. These improvements are not 

 slight; they are fundamental eminently worthy the attention of the mathematical 

 teacher, and give a character of unity to the work which at once distinguishes it from 

 all others on this subject. 



From C. M. WRIGHT, Associate Principal of Mount Palatine Academy. 

 I have examined Dodd's Arithmetic, and am fully persuaded that it is superior to 

 any other with which I am acquainted. I could speak in detail were it necessary ; 

 but all that is required to establish its reputation and introduction, is to have it 

 known by teachers.
