His father, John, a Staffordshire man, was one of a party of four mechanics who were sent by Boulton and Watt to Philadelphia about 1790 to set up a steam engine for the city water-works and who in 1793-1794 built at Belleville, N.J., the first steam engine constructed wholly in America; he made a fortune in the manufacture of furniture, but lost it by the burning of his factories.
There he continued his literary and scientific labours, enjoying congenial intercourse with such men as Matthew Boulton, James Keir, James Watt and Erasmus Darwin at the periodical dinners of the Lunar Society.
Watt regards it as closely allied to G.
Watt considers many of the Egyptian cottons to be races or hybrids of G.
According to Watt there are many hybrids in American cottons between G.
Watt dissents from this view and classes these Indian cottons as G.

B =9000, at a frequency of loo per second, was only 0.254 watt per pound, as compared with 0.382 for the Swedish iron.
The Royal Scottish Museum, structurally united to the university, contains collections illustrative of industry, art, science and natural history; and Minto House college and Heriot-Watt college are practically adjuncts of the university.
The Heriot-Watt college is subsidized by the Trust, and Heriot's hospital is occupied as a technical school.
Watt, when he invented the steam engine, laid down the principles on which it is based, and they hold good to the present day.

In the same year another patent was granted to C. Watt for a similar process, involving the employment of an externally generated current.
Many patents have been taken out in this branch of electrochemistry, but it is to be remarked that that granted to C. Watt traversed the whole of the ground.

These points were discussed at a fresh congress where about 900 persons were present, and where Vadian (Joachim von Watt, the reformer of St Gall) presided.
Steam-power was applied to them by Matthew Boulton and Watt in Birmingham in 1788, and was adopted by the Royal Mint, London, in 1810.
In 1887 he returned to England and became professor of chemistry at the Heriot-Watt College, Edinburgh.
It was here that, on his invitation, James Watt constructed a model of his steam-engine, which was tested in a now disused colliery.
Meters intended to measure electric energy (which is really the subject of the sale and purchase) are called joule meters, or generally watt-hour meters.
Hence the meter is a watt-hour meter and measures electric energy.
(London, 1898), 27, 547 so arranged as to indicate the consumption in Board-of-Trade units (i Board-of-Trade unit = 1000 watt-hours).
It can be constructed to be either an amperehour meter or a watt-hour meter, but is usually the latter.
In Intermittent Registering Meters some form of ampere-meter or watt-meter registers the current or power passing into the house; and a clock motion electrically driven is made to take readings of the ampere-meter or watt-meter at definite intervals - say, every five minutes - and to add up these readings upon a set of registered dials.
When this is the case, the number of revolutions of the meter in a given time is a measure of the watt-hours or energy which is passed through the meter.
The counting mechanism and dials may be so arranged as to indicate this energy directly in watt-hours.
Such a test is made by determining with an accurate ammeter or watt-meter the current or power supplied to a circuit for a period measured by a good clock and comparing with this the actual reading of the meter 2 See Journ.
His eldest Son, William Henry Perkin, who was born at Sudbury, near Harrow, on the 17th of June 1860, and was educated at the City of London School, the Royal College of Science, and the universities of Wiirzburg and Munich, became professor of chemistry at the Heriot-Watt College, Edinburgh, in 1887, and professor of organic chemistry at Owens College, Manchester, in 1892.
Among other publications by him were An American Four-in-hand in Britain (1883), Round the World (1884), The Empire of Business (1902), a Life of James Watt (1905) and Problems of To-day (1908).
Electrolytic processes had, in fact, been considered since 1851, when Charles Watt patented his method for the production of sodium and potassium from fused chlorides.
Since there are 8760 hours in a year, if such an instrument were connected continuously to the circuit it would take up energy equal to 263,000 watt-hours, or 260 Board of Trade units per annum, If the cost of production of this energy was only one penny per unit, the working expenses of keeping such a voltmeter in connexion with a circuit would therefore be more than £i per annum, representing a capitalized value of, say, £io.

The next important step seems to have been taken in the 4th century when some forgotten Watt devised valves for the bellows.

In virtue of a Continuation Class code, technical and specialized education is given in day and, chiefly, evening classes in various centres, the principal being the Heriot-Watt College, Edinburgh; the Edinburgh and East of Scotland College of Agriculture; the Glasgow and West of Scotland Technical College; the Glasgow School of Art; the Glasgow Athenaeum Commercial College; the West of Scotland Agricultural College; the Dundee Technical Institute; Gray's School of Art, Aberdeen; the Edinburgh Royal Institution School of Art, and the Edinburgh School of Applied Art; but wellequipped classes are held in most of the large towns, and several county councils maintain organizers of technical instruction.
As regards agricultural education, the county is found to be in most cases too small an area for efficient organization, and consequently several counties combine to support, for instance, the East of Scotland Agricultural College - a corporation consisting of the agricultural department in the University, the Heriot-Watt College and the Veterinary College in Edinburgh, - the West of Scotland Agricultural College, Glasgow, and the agricultural department in Aberdeen University.

A more convenient unit of work or energy, in practice, on account of the smallness of the erg, is the joule, which is equal to 10.7 ergs, or one watt-second of electrical energy.
Other convenient practical units of the same kind would be the watt-hour, 3600 joules, which is of the same order of magnitude as the kilocalorie, and the kilowatt-hour, which is the ordinary commercial unit of electrical energy.

These two gases, as Cavendish and James Watt had shown in 1784, were actually the constituents of water.

Since then additions and improvements have been periodically in progress, and there are now several tidal harbours - among them Victoria harbour, Albert harbour, the west harbour, the east harbour, the northern tidal harbour, the western tidal harbour, the great harbour and James Watt dock (completed in 1886 at a cost of X650,000 with an area of 2000 ft.
Greenock was the birthplace of James Watt, William Spence (1777-1815) and Dr John Caird (1820-1898), principal of Glasgow University, who died in the town and was buried in Greenock cemetery.
