Penrose (F. C.)— on a method of predicting by 



GRAPHICAL CONSTRUCTION, OCCULTATIONS OF 

 STARS BY THE MOON, AND SOLAR ECLIPSES FOR 

 ANY GIVEN PLACE. Together with more rigorous methods 

 for the Accurate Calculation of Longitude. By F. C. Penrose, 

 F.R.A.S. With Charts, Tables, etc. 4to. \zs. 



The author believes that if, by a graphic method, the prediction of 

 occultations can be rendered more inviting, as well as more expedi- 

 tious, than by the method of calculation, it may prove acceptable t» 

 the nautical profession as well as to scientific travellers or amateurs. 

 The author has endeavoured to make the whole process as intelli- 

 gible as possible, so that the beginner, instead of merely having t» 

 folloto directions imperfectly understood, may readily comprehend 

 the meaning of each step, and be able to illustrate the practice by the 

 theory. Besides all necessary charts and tables, the work contains 

 a large number of skeleton forms for working out cases in 

 practice.

It has been the endeavour of the author to arrange the most important 

 facts and principles of Modern Chemistry in a plain but concise 

 and scientific form, suited to the present requirements of elementary 

 instruction. For the purpose of facilitating the attainment oj 

 exactitude in the knowledge of the subject, a series of exercises and 

 questions upon the lessons have been added. The metric system ej 

 weights and measures, and the centigrade thermometric scale, are 

 used throughout this work. The new edition, besides nero wood- 

 cuts, contains many additions and improvements, and includes thi 

 most important of the latest discoveries. " We unhesitatingly pro- 

 nounce it the best of all our elementary treatises on Chemistry. " —
