    Clark's Improvements in the Preparation and Application of Baths, $c. its complete subdivision, when it escapes from the orifice H it becomes distri¬ buted in the bath box I. The size of orifice H should be in proportion to the quantity of liquid to be subdivided in a given time; in some cases it is about one-sixteenth of an inch in diameter. The dotted lines in the Drawing show 5 another form of bath box. The inclination given to the jet in the box may be varied as desired. Another method, which dispenses with the use of the cup wheel, consists in the employment of a cotton wick, which draws up into the reservoir the three quarts of water to be conducted into the tube almost drop by drop to the 10 orifice of escape of the compressed air at its entrance to the box. In this manner the subdivision is effected in a very easy manner, which is of great service for certain descriptions of water or mixtures of liquids. When there are matters held in suspension in the water, it may be agitated by the force of a spring or weight. The wick above described may be replaced by two small 15 capillary tubes, with orifices opposed the one to the other. The flow of water should be very slow, almost drop by drop, and may be regulated by a level or head of water so as to furnish the exact quantity required. The liquid may be further supplied to the subdividing jet by means of a cock, which is regu¬ lated so as to supply any quantity at will. In all cases the reservoir con- 20 taining the liquid for the bath should be arranged so as to be heated by a bath heater or in any other manner. When the bather has his head enclosed in the box, this is made of a peculiar form, and the front part is glazed. The principle forming the basis of the present Invention being thus deter¬ mined, it will be unnecessary to give details of other methods of subdividing the 25 liquids, such as by percussion against hard substances, centrifugal force, filtra¬ tion, or other suitable means. The form of bath box or its accessories, and the method of heating, if required to be heated, the flow of the water, and the cocks for the supply of air, water, or other fluid may all be varied according to circumstances. I will further add a description of apparatus which I use 30 for this mode of balneation, and in which I have adopted the method of sub¬ division of the water produced by the blowing machine. Sheet 2, A, vessel containing the liquid to be employed for the bath; B, vessel of larger size for receiving warm water up to the point indicated by the letter C. This vessel is completely enclosed in wood to preserve as much as 35 possible the warmth of the water it contains or the liquid intended to be sub¬ divided, and also of the air which serves for the subdivision. D, tube for the introduction of water into the vessel A; E, funnel for the introduction of warm water into the vessel B; F, outlet cock of vessel A ; G, outlet cock of vessel B ; IT, inlet tube for the passage of air into the vessel B.
