Page 13 - The Society took a very active part in the measurement of a degree of latitude, afterwards in the length of a pendulum vibrating seconds in the latitude of London, and in the comparison of the British Standards with the Linear Measure adopted in France. A committee was appointed to compare the Society's Standard yard with that of the Exchequer. Later, in 1834, when the Standard yard was lost in the destruction by fire of the Houses of Parliament, a Commission (all the members of which were Fellows...

Page 21 - In my opinion, the scientific deadness of the nation is mainly due to the too exclusively mediieval and classical methods of our higher public schools, and can only be slowly removed by making in future the teaching of Science, not from text-books for passing an examination, but, as far as may be possible, from the study of the phenomena of Nature by direct observation and experiment, an integral and essential part of all education in this country.

I proceed to the award of the medals. Copley Medal. The Copley Medal is awarded to Sir William Crookes, FRS, for his experimental researches in chemistry and physics, extending over more than fifty years....

The following may be taken as an illustration of the way in which the table of composition of food products and the dietary standards may be practically applied. Suppose the family consists of four adults, and that there are on hand or may be readily purchased the following food materials: Oatmeal, milk, sugar, eggs, lamb chops, roast...
Page 9 - Claimants at once came forward for portions of the estate, and the property was in so unsettled a state as to title, and so much out of repair, that after much money had been spent on repairing the College and great exertions made in vain to procure a tenant, the President was authorised to sell the estate to the King for the sum of £1,300; the Council voting their thanks to him for " thus disposing of a property which was a source of continual annoyance and trouble to them.
Page 20 - ... generations of fellows have unsparingly contributed of their time to the introduction and promotion, whenever the opportunity was afforded them, of scientific knowledge and methods into the management of public concerns by departments of the Government. The financial independence of the Royal Society, neither receiving, nor wishing to accept, State aid for its own private purposes, has enabled the society to give advice and assistance which, both with the Government and with Parliament, have...
Page 465 - From the nature of the fracture it is evident that this fibrous or cellular core is a source of weakness and must considerably reduce the tenacity of the metal. It is possible that the flowing action to which the metal has been subjected may have caused the disengagement of occluded or dissolved gases at the moment of the passage of the C into the A phase. A proportion of the gas disengaged would naturally be driven in towards the centre of the wire, as the outer skin must be comparatively impervious....

In other words, the critical pressure of water is ten times that of hydrogen, and the critical pressure of carbon is ten times that of water. Now 15 tons on the square inch is not a difficult pressure to obtain in a closed vessel. In their researches on the gases from fired gunpowder and cordite, Sir Frederick Abel and Sir Andrew Noble obtained in closed steel cylinders pressures as great as 95 tons to the square inch, and temperatures...
