108 Domestic Notices : — England. 



of agriculture which cannot be imported ! Let our landlords abandon the 

 absurd idea that they can gain by monopolies, which deprive industry of 

 the means of . purchasing." The Globe, the Scotsman, the Spectator, the 

 Examiner, and many of the country papers, concur in these views, and 

 believe with us that the interests of the agriculturist and the manufacturer 

 are essentially the same. 



The editor of the professional and miscellaneous department is a particular 

 friend of ours, of various scientific acquirements, and of very considerable 

 experience in the management of landed property, and as a rent-paying 

 farmer on a large scale in Lancashire and Norfolk. A new feature in this 

 paper is that of embracing horticulture ; on which account it deserves the 

 particular patronage of gardeners. — Cond. 



Metkley's Fire-places have been recommended by us (Vol. V. p. 238.) as 

 more to our taste than any which we have ever seen. We have this winter 

 had a good opportunity of observing to what a very considerable extent 

 these fire-places burn their own smoke, more especially when a large fire is 

 kept up. We therefore again recommend them ; and at this season, when 

 heat forms an important subject of consideration, we would also call 

 attention to Mr. Cottam's mode of heating the rooms of a house, or an 

 office, library, or conservatory, by circulating hot water from the boiler 

 of a common kitchen range ; and to the great improvement on Sylvester's 

 mode of heating, by White and Veitch. — Cond. 



Sylvester's Mode of heating by hot Air is admirable both as a system of 

 diffusing heat and of diffusing fresh ah ; but, in London at least, it has two 

 objections, that of being very expensive, and of carrying in dust to the 

 rooms. Messrs. White and Veitch have succeeded, if not in entirely re- 

 moving, at least in greatly alleviating, these objections. That of first cost 

 they have lowered fully one third, by the employment of a cylindrical 

 cockle of more than double the height of Mr. Sylvester's, and by heating 

 the ah - by simply passing it in a thin stratum between this cylinder and a 

 cylinder of brickwork, every where of equal width, and perfectly smooth. 

 The ah passes so rapidly that it is not burned. Those who are acquainted 

 with the intricate but highly scientific form of Mr. Sylvester's cockle, will 

 easily conceive that Mr. Veitch's must come much cheaper at first, and be 

 less likely to go out of repair afterwards. The air is freed from the dust or 

 soot, which it holds in suspension, by passing it over water before it enters 

 the funnel which conducts it to the cockle to be heated. It may easily be 

 conceived how this may be done, and that different modes may perhaps 

 answer equally well. Mr. Veitch collects the air from four openings in 

 opposite directions into one perpendicular funnel, perhaps a foot in height ; 

 he next spreads it thinly over a surface of perhaps two square yards of 

 water ; from this it rises several inches, and, descending 2 or 3 ft. in four 

 thin sheets, it is again united over a broad surface of water, and thence 

 passes into the funnel leading to the cockle. The water is renewed once 

 a week, and is found to contain a considerable deposit, the grossest in the 

 first or upper basin. The objection that immediately occurs to passing 

 the air over water is, the moisture that it will take up ; to which Mr. Veitch 

 replies, that when fires are wanted in his cockles, or those of Mr. Sylvester, 

 the open ah is at a temperature which scarcely admits of any evaporation. 

 This purifier of the ah may be placed before the entrance to the funnel of 

 any of Mr. Sylvester's stoves ; and we have no doubt it will be adopted by 

 all who have an opportunity of witnessing its effects. Mr. Veitch has 

 applied them at the British Museum, the Post-Office, and at the London 

 University. Heating by hot ah requires a great deal more fuel than heat- 

 ing by hot water, which, whether in dwelling-houses or hot-houses, is the 

 most economical of all modes of heating ; but the hot-ah* system must be 

 more healthy, because the air is continually renewed. To render the hot- 

 air system perfect, at least for small houses, it should be connected with a
