"The expense of converting a loose box into a hot-air bath is so trifling that the experiment may be made at no great cost. London has already many Turkish Baths for bipeds, and I hope Newmarket will not be without one for quadrupeds. Col. Knox has testified to its beneficial results upon horses in Ireland; and Col. Towneley has one at his training stables at Middleham, which, I believe, has answered every expectation. "In the treatment of disease I have often experienced the benefit of hot air; for in former days, when maladies in the horse were more rapid and acute than we now usually meet with them, and were generally ushered in by a cold shivering fit, it was my constant practice at Carlton House stables, when such a case occurred, to take the horse at once into the men's kitchen, and put him before the large fire which always kept it at a high temperature. By the heat, with the help of constant friction, I generally succeeded in cutting short the duration of the cold, clammy sweat, which is always indicative of mischief more or less serious. Were it for the treating of disease only, if I had a stable of valuable horses under my care, I would soon have also a hot-air bath. "Yours, &c., W. J. GOODWIN. "Hampton Court, Nov. 28th, 1860." I have assumed for the skin the rank of a respiratory, of a breathing organ; and have endeavoured to show that the cooling and drying operations of the Frigidarium are an important part of the bath, as their performance is associated with the exposure of the skin to the atmosphere. Mr. Witt urges the prolongation of this period of the bath to as lengthened a degree as possible; and he delights to tell his auditors, dispersed around him like Roman senators in the Forum, and with no other garment than a cotton scarf, variously and negligently twined around their bodies--that this was the period when Pliny betook himself to his garden, and in the full light of the sun, and refreshed by the sweet breath of the unfettered winds of Heaven, walked in pleasant contemplation on a terrace carpeted with a beautiful little moss of velvet softness. We read that Sir Walter Scott indulged in this kind of atmospheric bath; we recognise in it the special charm and much of the value of the river bath and the sea-shore bath; and we are not startled when we hear from the mouth of an advocate of the Turkish Bath, Dr. John Le Gay Brereton, in a lecture delivered in Sheffield in 1858, that--"After leaving the hot room in Bradford bath, bathers were in the habit, last winter, of jumping into a bed of snow which had been collected for the purpose. I have myself spent the whole night in the woods at Blarney, without any clothing save the bath-sheet, after coming out of Dr. Barter's bath at that place. This was after a ball, when, with several other gentlemen, we had retreated to the bath for the sake of refreshment from fatigue. So delightful was the cool
