Allow me to introduce to you and to your brother officers of the old --th Captain Osman Rioni (late of the--I am sorry to say it--Russian service), who has been for some time in London teaching our Life Guards the lance exercise, and who for the last three months has been the lion of the club-houses. He arrived among us a staid and respectable Mohammedan, very prone to sit cross-legged on the floor, to dip his fingers in the gravy, and to grasp his knife if you gave him a slice of ham with his fowl; but he leaves us much addicted to balls, vingt un, champagne suppers, the polka, and the waltz. In short, in one season, we have polished him up in good style, and completed an education which had been somewhat neglected during his rural life among the Caucasus. You, perhaps, know the history of himself and his horse--for the morning papers get hold of everything. Conyers of the Blues offered him £500 for the nag; but he won't sell it for any known amount of the ready. Look at its legs and chest; I never saw such an animal! The captain has been an honorary member of our mess while in London--a hint this, for your fellows. He is now on his way home to the Kuban (wherever the devil that may be), and so you gentlemen of the Line in Gibraltar must look to the state of his exchequer, and pass him on to the next station, as Conyers has given him letters to some of the Rifles at Malta. I could easily have procured him a troop in our new Turkish contingent; but home he must and shall go, he says, and his own story will best let you know why. To-morrow our battalion will change its quarters, and commence the arduous march from St. John's Wood Barracks to those in Portman-street, and from thence to Trafalgar-square, and I shall follow in my cab; but you may see me ere long, for I am to sail with the next draught of ours for the Crimea, where the shiny splendour will be taken out of our Brahmins in the muddy trenches--ugh! Give my remembrance to Dick Ramble--ask him what his next book is to be about; and so, my dear Jack, I remain, &c., &c. The wishes of Sir Henry, and the efforts he and his brother officers of the Grenadier Guards (most of whom will remember the affair I allude to) made it imperative upon "Ours" not to be behind them in kindness to this stranger.
