The multiple of the gearing in the Great Britain is 3 to 1, and there are 17-1/2 square feet of heating surface in the boiler for each nominal horse power.

Outdoors the sun beat fiercely upon the heads of toiling men and horses while the heat waves danced with a dazzling shimmer along the brick pavements.

The fact is, the young fellow is a good-hearted creature enough, only too fond of his jokes,and if it were not for those heat-lightning winks on one side of his face, I should not mind his fun much.]

The houses were mostly mere board shanties, tightened by pasting newspapers over the cracks inside, where the women of the family had time for such work; and the heating apparatus was generally a wood-burning cook-stove, with possibly an additional coal heater in the front room which could be fired on Sundays, or when the family was at home to tend it.

Avery's eyes were on the thick heat-haze that obscured the sky-line.

In the experiments made at the laboratory of the School of Mines in Madrid it yielded four per cent. of ashes, and a heating power of 4,825 caloria; i.e., by the burning of one part by weight 4,825 parts by weight of water were heated to 1° C. Good pit-coal gives 6,000 cal.

The voluntary factor, as a means of regulating the heat loss in man, is one of great importance.

(3) He then refers to the actinometer and pyroheliometer, instruments for measuring the actual heat derived from the sun, and also to the Bolometer, an instrument invented by Professor Langley for measuring the invisible heat rays, which he has proved to extend to more than three times the length of the whole heat-spectrum as previously known, and has also shown that the invisible rays contribute 68 per cent, of the sun's total energy.

I was beastly cold, for the whole place is without any kind of heating pipes or furnace, as I had noticed during my search, so that the temperature was sufficiently uncomfortable to suit my frame of mind.

At each end of each building there was a fire place built and used for heating purposes.

Now it required a certain number of heat units to produce this steam which after doing its work gives back all its heat again to the feed water and it would be a very interesting problem for some of the young engineers, as well as the old ones, to determine just what loss if any is sustained in this manner of supplying a boiler.

She dreamed of echoing halls hung with Oriental draperies and lighted by tall bronze candelabra, while two tall footmen in knee-breeches drowsed in great armchairs by reason of the heating stove's oppressive warmth.

Heating system could be shot.

This idea was the discovery of some form of heat-engine which should be more economical than the steam-engine, especially as it was in his day.

The three curves which begin at the lower left hand corner and rise to the right are heat curves and represent the increase of temperature corresponding with different pressures and volumes, assuming in one case that the temperature of the air before admission to the compressor is zero, in another sixty degrees, and in another one hundred degrees.

During the whole of its early growth, and till it acquired nearly its present diameter, its rate of aggregation was so slow that the planetismals falling upon it, though they might have been heated and even partially liquefied by the impact, were never in such quantity as to produce any considerable heating effect on the whole mass, and each local rise of temperature was soon lost by radiation.

Furies, lend me your fires; no, they are here, They must be other fires, materiall brands That must the burning of my heat allay.

As she left the mill those sultry evenings, with the heat mists still tremulous over the valley and heat lightnings bickering in the west, she went with a lagging step up the village street, not looking, as had been her wont, first toward the far blue mountains, and then at the glorious state of the big valley.
