The regiment went through its business very well; with less affectation,--perhaps with less precision,--than our marvellously trained three-year horse-soldiers; but with more true military coolness, and with the steadiness and ease resulting from long habit: all their evolutions too were more rapid, from the excellence of their horses, with which those of the Continent are not to be compared. The English cavalry has gained immensely in command of the rein, and in military seat, since the last war, which is mainly to be ascribed to the care and attention of the Duke of Wellington: the men had their horses as well in hand as the best of ours. The extraordinary thing, according to our notions, was to see the perfect ease with which fifty or sixty officers in plain clothes,--several General officers among them, some in undress jackets and top-boots, some in frock-coats and coloured cravats,--took part in the review, and thronged around the Inspecting General, who with his two aids-de-camp were the only men in uniform, except the regiment. Nay, even some supernumerary officers of the regiment itself, not on actual service, rode about with him in civil dress and shoes,--a sight which would have given such shock to the nerves of a ---- general, as would have endangered his intellects for ever. In a word, one sees here more of the reality; with us, more of the form. Here, 'tis true, the clothes do not make the man; and this simplicity is sometimes very imposing. R---- told me that this regiment was originally formed by the Tailors' Company, at the time of the threatened French invasion, and at first consisted entirely of tailors. They are now transformed into very sturdy martial hussars, and fought with great distinction at La Belle Alliance. _June 18th._ Since the day before yesterday I have returned to the old track. I 'débutai' with four balls, and a dinner at Lord Caernarvon's, where I met Monsieur Eynard, the celebrated Philhellenist, whose pretty wife manifests an equal enthusiasm for the Greek cause. Yesterday I dined at Esterhazy's, and met a young Spaniard whom I could not help wishing an actor, that he might play Don Juan, for he seemed to me the perfect Ideal of that character. With the tones of the dramatic Pasta, whom one hears every evening, ringing in my ears, I went to bed. This evening there was a concert at the tall Duke's, where every body was in raptures at old Velluti, because he sang well once upon a time. He lives here upon his ancient fame. From thence I went to one of the prettiest balls I have seen in London, at the house of a Scotch woman of rank. The largest room was entirely decorated with paper lamps made in the forms of various flowers, very tastefully grouped.
