Answer to Professor T. S. Davies''s Complaint i-espeding his 

 Paper on the Hour-lines of the Antique Sun-Dials. By 

 William Cadell, Esq. F. R. S. L. & E., M. W. S. &c. 



to the editor of the edinburgh philosophical journal. 

 Sir, 



May I beg the favour of your inserting the annexed state- 

 ment. — I am, Sir, very truly yours, W. A. Cadell. 



The following statement is for the purpose of shewing the er- 

 roneous nature of a publication in which my name is brought 

 forward, and which, as I suppose, appeared in one of the scien- 

 tific journals in 1831. As the existence of that publication did 

 not come to my knowledge till lately, it is only now for the first 

 time that I have an opportunity of contradicting it, and justify- 

 ing myself against any imputations it may contain. 



The passage by which I was first informed of the existence of 

 the publication, is from a letter which formed part of a corre- 

 spondence I had in 1834, with Professor T. S. Davies of the 

 Royal Military Academy, Woolwich. He writes, " I own to 

 you that I did insert a communication, either written, or through 

 some authenticated friend, respecting the part which you took 

 in the business (that is to say the business respecting Mr Davies's 

 paper), of which I complained." From this passage I infer the 

 existence of the publication ; and although I have not seen the 

 publication itself, I will nevertheless proceed to shew that Mr 

 Davies's complaints, in whatever terms they may be expressed, 

 are groundless, and that I took no " part in the business," ex- 

 cept giving a favourable opinion of Mr Davies's paper when it 

 was submitted to me. 



Several years after the publication of my first paper on the 

 ancient hour lines, I wrote a second paper on the same subject, 

 which was deposited by me in the hands of Dr Roget, Secretary 

 of the Royal Society, in the month of June, being about five 

 months before I knew that any one was employed in researches 

 on the same subject, and the paper remained unaltered in the 

 hands of Dr Roget, till it was read at a meeting of the Society.
