Rh to the size of the machine, and they should be placed in one or more straight lines. To one side of this lamp he fixes an oven, for the purpose of washing, or baking; one side of the former is applied to one of the latter, in an inclined direction, so as to come in contact with the flame of the wicks. On the other side of the lamp, he places another oven, which may be either with a straight side next the lamp, or may incline in the same direction as the former; but, if this latter oven incline from the flame, it will serve only to keep any fluid or solid substances in a hot state. The two sides of the ovens will form a flue, or chimney, and convey the remainder of the heat upwards to a vessel of any shape, which may be put over them, for the purpose of raising steam, either to turn a jack, or boil water for tea, &c.; and on the top of which, another steaming vessel may be placed. A frying, or boiling pan may also be occasionally substituted for that last mentioned. Any of these utensils can be used separately with, or over, the lamp; and, if baking or roasting only be required, that purpose will be better effected, by having an oven so constructed as to receive the whole heat of the lamp, or lamps, which ought to be surrounded with a case, for confining the flame, with an open space at the bottom to admit the heat, and another at the top to give it vent.
