London, June 2. 
I lost no time on receiving your letter of the 30th, of speaking to Lord Sidmouth, on the subject of your situation and reasonable expectations, and I must do him the justice to say, that he expressed to me the greatest anxiety to have an opportunity of appointing you to some office, such as he conceived your services merited.—It is impossible to say when such an opportunity may occur; but you may rely upon the case neither being forgot nor neglected.
I am, Sir,
Your most obedient humble Servant,
[To] Capt. Raynes.
