NOTICES TO CORRESPONDENTS. 

 Inquiries respecting subjects connected with Engineering, Practical and 

 Theoretical Science, Architecture, and Patent Laws raust be addressed to the 

 Editor by the 18th of each month, to obtain answers in the following num- 

 ber of tliis Journal. 



Mathemaiicus. — Your difficulty in assuming 2 cos = .r+ -, because every 



X 



numerical value of x makes cos 6 greater than 1, will vanish on considering 

 X a quantity partly rational and partly irrational. For instance, assume 



^ = (1 - a) - (- g) , then since 1 = ( 1 - a) - ( - o), we have - = 



XX 1 i 



(1 - a) + (- fl) » and therefore .i -i- - = 2 (1 - a) . This is merely 



one instance, but your own ingenuity will suggest many others. 



£^ B. One of the best works treating on mechanics, without the use of 



mathematics, is that of the Society for Diffusion of Useful Knowledge. If 

 you mean by a *' popular" treatise, one by which you may learn without 

 study, there is no such work extant : no royal road to learning has been yet 

 discovered. 



ji/._By far the easiest way of calculating compound mterest for a great 

 number of years is by aid of logarithms. The method is fully detailed in 

 books of logarithms.
