These dances are got up at very little expence or preparation. One of the ladies presides at the piano; the refreshments are cakes, sweetmeats, and liqueurs: a few dollars provides for all; and I like their plan--it looks more like a friendly entertainment. The sumptuous repasts provided on such occasions in England, bespeak so much of ceremony as considerably to mar the pleasure. On birth-days, compliments are sent and received, with presents of sweetmeats, &c. and dinners and tertulias are given. Those days are more kept up than with us; but the itinerant musicians, about the doors, has a little fallen off lately. Sweetmeats are much eaten, and by the children in large quantities. In coffee-houses they sprinkle the toast with sugar: an English child would call them "sugar-babies." I am not dentist enough to decide whether this is one of the causes of decayed teeth, so often observed in young people, and the prevailing malady of the tooth-ache; but persons are continually seen with their faces tied up for this complaint: it is, indeed, a disease of the country. Bad teeth is a sad drawback, as they are both "useful and ornamental;" and the purchase of new teeth and gums, in Buenos Ayres, would be rather difficult: besides, all the world must know about it. In London and Paris, such things pass as nothing. When walking in public, the female rarely takes the arm of a gentleman, except it be night. This seems to us an unsocial fashion. At dark, however, the restriction ceases, and ladies will then honour us by accepting our arm: with married persons this is more common. The Englishman and his wife, in spite of Spanish modes, are seen trotting comfortably along the Alameda, on a Sunday, arm-in-arm, as if at home. Neither is it the fashion for gentlemen to escort the ladies, but to the theatre, or public places: their visits and shopping are in company only with their own sex. If a fair lady should wave this rule, and allow us to proceed by their side for a few streets, it would be the height of vulgarity to offer the arm. In England we have other notions of gentility. At the ball room, the females sit together, when not engaged in dancing. During this pause, some gentleman will, with hesitating steps, approach them, and solicit a lady to waltz, or dance a minuet with him. The Spaniards pride themselves upon the delicacy and respect with which they treat the females; and though there are many Spanish customs which I think "more honoured in the breach than the observance," this is one, I trust, will last for ever.
