Here’s a letter to the editor of The Times, dated 1st June 1864:
TO THE EDITOR OF THE TIMES.
Sir, — On my arrival home late yesterday evening a “telegram,” by “London District Telegraph,” addressed in full to me, was put into my hands. It was as follows :–
“Messrs. Gabriel, dentists, 27, Harley-street, Cavendish-square. Until October Messrs. Gabriel’s professional attendance at 27, Harley-street, will be 10 till 5.”
I have never had any dealings with Messrs. Gabriel, and beg to ask by what right do they disturb me by a telegram which is evidently simply the medium of advertisement? A word from you would, I feel sure, put a stop to this intolerable nuisance. I enclose the telegram, and am,
Your faithful servant,
M.P.
Upper Grosvenor-street, May 30.
(thanks to Tony Finch for the forward)
