On the Stanhope Temperament. 143 



For explaining these and other musical terms, which have 

 occurred in a very careful perusal of Mr. Overend's manu- 

 scripts, and Dr. Callcott's additions therein, 1 have enclosed 

 a copy of a table* (sec Plate V.) that I drew up to assist me 

 in reading and comparing them, which may prove accepta- 

 ble to your musical readers in general, and contribute per- 

 haps towards fixing the nomenclature of this science. I 

 need now only add that f = -149661 x 2, and m = 

 •007S631 X 2; these numbers being decimals of S, or lo- 

 garithms of a particular kind, wherein the index 1 is equal 

 to 2. — I am

XX. A Letter to His Royal Highness the Duke of Cumber- 

 land, from Dr. J. W. Callcott, respecting the Stan-

To His Royal Highness the Duke of Cumberland. 

 May it please your Royal Highness,

 and takes so great an interest in the new Temperament of 

 the Piano Forte, which is now so much the suljject of con- 

 versation in the Musical World, I hope that the present 

 liberty will be excused. 



Earl Stanhope has just sent me a Letter on his System, 

 which will throw great light on the matheinctiical part of 

 the subject, in answer to that contained in Mr. Tioloch's 

 Philosophical Magazine of April last, by Mr. John Farev. 



• As it would be difficult to get this curious table executed correctly in

 ceeding number. — A. T.
