28 a fireplace closed in front with a regulator to ashpit door to regulate the draught:, flue pipe passing through the outer base , and conducted out of the house at any convenient part; , water space round the fire and flue pipe; , return pipe for circulating the water; , small funnel or small cistern for supplying the water.

The general dimensions are as follows:&mdash;Fire-box, twelve inches by sixteen inches; outside pipe, six inches diameter, inside flue pipe, three inches diameter, which leaves a space of one and a half inch for water.

The cost will vary according to size and length of house, &c. The sketch represents a twenty-feet house, with apparatus eighteen feet long. The cost of one of the dimensions given will be about £5, made of strong galvanized iron.

The advantages of this arrangement is the portability, with the economy of fuel and equal distribution of heat along the front of the house.

In a large or extensive range of houses the pipes can be carried in any direction, as any other hot-water applications, and two or more fireplaces can be attached with the fireplace outside the building, or inside with an air pipe from without to supply air to the fire if found injurious by taking it from the inside of the house.

The manufacturer is Mr. J. J. Carter, Peak Hill, Sydenham.

The Thermostat-Thermosiphon, introduced to public notice by our friend M. Sisley, of Lyons, may be considered as an ingenious modification of Riddell's slow combustion stove, and, like it, is simply placed where it is to stand, and requires no brick-setting. It is a peculiarly safe apparatus, the fuel and flames being on all sides in contact with iron, which cannot become excessively heated, because that is in contact with water. Hence, this apparatus is well adapted to place in an entrance-hall for heating the adjoining apartments, and perhaps a greenhouse or conservatory not far removed. M. Sisley, in describing it to us, says:

&ldquo;By stirring it once in the morning and once at night, we could, by burning good coke, set light to the fire on the 1st of October, and keep it burning to the 1st of May, at an expenditure of from 16 to 24 kilogrammes of coke every twenty-four hours.

&ldquo;The apparatus could be placed in the same locality&mdash;that is to say, in the plant house&mdash;destined to be heated, and its
