Onr of the surest. indications of the value of the 
iPonmaise HEATING is the eagerness. with which it 
is assailed. We should have despaired. of its 
success had it been treated with indifference ; but 
its advantage is so obvious that people are annoyed 
at not having found it out themselves. Some think 
it a;reproach to their own sagacity that a furnace, 
a hole in a wall, a drain, and a wet blanket should 
do what they have only accomplished by boilers 
sand pipes, with their returns, flanges, waterways, 
staps, valves, stopcocks, tanks, and cisterns. Others, 
‘who can admire nothing but what is complicated, 
who value every thing in proportion to its dearness 
and imposing appearance, and despise all that is 
‘simple, sneer at the idea of so small a matter, 
declare their conviction that the scheme is an 
cabsurdity, and wonder how men can fancy that they 
‘are advancing by stepping backwards. A third 
Grass, in their usual tone, coolly deny that any 
other results have been obtained at Polmaise than 
‘could have been had without a heating apparatus 
ofany sort. And, fizally, a fourth class protest that 
‘they have themselves tried to do the thing, long 
om and abandoned it as impracticable. Aie

E: s«uener at Polmaise, as to the diffi- 
--uy. Of keeping down the temperature, goes for

| nothing ; the scorching of leaves, by the air rushing 
from the heating chamber, for nothing ; the agita- 
tion of the atmosphere, for nothing ; the necessity of 
placing the entrance of the hot air in the back wall, 
because of the heat, for nothing: all these things 
are nothing; they are no evidence whatever of 
heating; they only show the advantage of a wet 
blanket. The testimony of persons who have 
visited Polmaise goes for nothing, when compared 
with our ingenious correspondent’s foregone con- 
clusions ; we trust that the new evidence afforded 
by Mr. Suzanzn, as to the working of a similar 
apparatus at Lord TwrEppatyr’s, will be more satis- 
factory to him. 
A Scotch gardener, in the neighbourhood of Stir- 
ling, denies that he was afraid of showing Grapes 
against those of Polmaise. Perhaps he will tell us 
why he and his neighbours did not show. But we 
must not devote further space to matters like this ; 
more important considerations claim our attention. 
It is proved to the satisfaction of reasonable men, 
by the apparatus at Polmaise, that it is possible to 
dispense with all the paraphernalia of hot-water 
apparatus by means of heated air, and suitable con- 
trivances for conveying it; that those conveyances 
are mainly currents produced in the atmosphere by 
the difference in density of the eold and heated air ; 
and that therefore the cost of warming buildings 
for plants is reduced to little more than the charge 
for brick-work and a furnace. Somebody says, 
“Oh! no; the Polmaise plan must have cost 207. ; " 
be it so. A hot-water apparatus would have cost 
50/., and would. have done no more. 
What it may be necessary to pay for heating a 
house on the Polmaise plan will depend exclusively 
on the size ofthe house itself, and the objeets to be 
gained ; upon the nature of the furnace employed, 
and the closeness with which the simplicity of the 
Polmaise apparatusis copied. If deviations are in- 
troduced, ne little more is done in one respect, and 
a little more in another, it may be improved, but, of 
course, will become more costly. Leaving this to 
the taste and pockets of the public, who will have 
plenty of plans laid before them, we shall content 
ourselves with a few general propositions, attention 
to which is indispensable. 
The kind of furnace which it may be most advan- 
tageous to employ cannot be decided without direct 
experiment. Perhaps a brick ARNOTT, constructed 
like those of Mr. Rivers, published last week, may 
suffice for small buildings. The Polmaise stove is 
one patented by Messrs. Haven, of Trowbridge ; 
that at Yester was made by Mr. Wurre, of Hadding- 
ton; another, said to be agood one, is Harr's, concern- 
ing which we this day publish a useful suggestion 
by Messrs, SrreHENSONs; and so also Hazarn’s 
tube stove will be applicable, provided itis possible 
to clean out the tubes without inconvenience. 
In short, it is not very material what stove is 
employed, provided regard is had to the circum- 
stances included in. the following. communi- 
cation with which we have been favoured by a 
correspondent (J. H. H.), from whom we could 
wish to hear more frequently, and which we now 
print without further comment. 
“Jn your observatious on the Polmaise system 
of heating, you refer to its being an undetermined 
point what kind of stove is best suited for fulfilling 
its conditions in. the most economical manner, 
remarking that in the case of a Joycr’s stove the 
results were not satisfactory, inasmuch as there is 
at first a tendency in it to draw in air as much from 
the house as from the drain. The cause of this 
appears to me to be obviously that a Jovcx's stove 
is merely an urn containing ignited charcoal; it 
has no flue to create a draught ; the air that feeds 
those who, admitting all the merit of tnc *° "n 
plan, which, however, they could never see be. S? 
depreciate it because of its want of novelty ; it is 
Peny S, says one; it is Mryrer’s, says another; 
it is SvrvrsTEWs, exclaims a third. And one 
gentleman expresses his astonishment (D) that men 
of science should not be more careful of producing 
as new that which is soold. He thinks they should 
be more tender of each other's reputation. We 
cannot be expected to do more than notice such 
trifling ; the public cares nothing about wire-drawn 
nistory ; men in active life are not registrars of 
patent inventions ; what really concerns the busy 
world is the goodness of a thing, not its age ; and 
provided a contrivance answers the purpose nobody 
Cares where it originated. Since, however; priority 
the fire enters through the top or cover of the urn, 
the gases of combustion issue by the same 
cde Tt is;true the latter, from their higher 
channel. . they emerge, have a. tendency to 
temperature as .. ~ ascending column of very 
tise; and there is au “tance above the stove 
feeble power for a short dis... ?«aed as to allo 
until their temperature is so far reau: “soutrali M 
their specific gravity to operate upon and... TAS, 
their further ascent. 
“A Jovcx's stove, therefore, placed in any situa- 
tion will draw in air from every. direction, and at 
first rather from above than below. If placed on a 
confined ease or chamber with two apertures, one 
above communicating with the interior of the house, 
the chamber becomes warmed by the heat reflected 
from the sides of the stove, an ascending current 
will begin io be established ; but I am inclined to 
“ink that the motion of the current we? 
times be sluggish wit 
remarks an~! Java a Stove. 
-ppıy M à modified degree to the Arnott 
and other stoves of slow combustion ; for though 
they have flues, the very principle on which their 
economical use depends is the controlled and 
slow admission of air through the fire and flue. 
Hence the motion of the current will be propor- 
tionally slow as the regulator restricts the-admission 
of air inside the stove. 
“ In the Polmaise method of heating the current 
of air from the drain, on reaching the stove, is 
divided into two parts ; one enters the stove, feeds 
the fire, and passes off by the flue; the other 
passes by the sides of the stove, and abstracting 
heat from them, enters the house. The vivacity of 
the current, therefore, other things being equal, will 
depend on the stove used being one ofgood draught ; 
and from circumstances mentioned, I should think 
Mr. Murray must have used one possessing con- 
siderable draught as well as great heating power: 
in fact,the two properties are very close companions. 
“The advantage of the Polmaise principle consists 
in the circulation of air it produces, which is not 
only beneficial in itself, but more equally and rapidly 
diffuses the heat communicated to it through an 
apartment of any kind ; and it is worthy of adop- 
tion in our own habitations as well as in houses 
for plants. It is caleulated to be of great service 
in small and cheap greenhouses in combination with 
an Arnott or any other of the economical stoves.

tation to a structure of this kind. S is an Arnott,

or other stove, surrounded by a close chamber or 
case. C, of wood, brick, or any other material that 
may be most convenient, built against or fixed to 
the back wall of the house. This chamber com- 
munieates below with the drain D, and there are 
openings (O) near the top, or they may be made in 
the top itself, through which the current of warmed 
air enters the house. A shallow pan of water (P 
isplaced on the top, from the edges of which depen: 
inside the chamber, strati@s of cotton or worsted 
thread (T) to moisten the heated air in its progress ; 
the water that drops from the strands may run into 
the drain, or be conveyed away in any other suit- 
able way. The flue F, of iron, is carried up inside 
the house; which I consider a beneficial arrange- 
ment, as a great deal of useful heat is lost by its 
being taken outside, as we often see it done. A 
current of heated gases is continually rising in the 
flue, which, as iron is an excellent conductor, assists 
materially in warming the air ofthe house ; and for 
the same reason itis also better than a brick flue 
or chimney. built in the wall, from which the air of 
the house derives no perceptible benefit in the way 
of warmth." 
It will also be desirable to bear in mind the fol- 
lowing rules :—
