Wide Slit

When editing the English translation of Schaliens ‘Spectrum Analysis,’ I discovered that the short account of the method of viewing the forms of the solar prominences by means of a wide slit, which I had the honour of presenting to the Royal Society on February 16, 1869, does not agree exactly in one respect with the account of the observation of February 13 as it was entered at the time in my observatory book. The short note was written at the suggestion of a friend during a Committee held in the Royal Society’s Apartments, and, as the concluding words show, was intended to be followed by a more detailed account of the method of observation. The point in question relates to the position of a second slit which was used to screen the eye from every part of the spectrum except that under observation.

The Body

Dear Dr. Sharpey,—I am anxious that you should read to the Royal Society a short note containing the results of some observations I lately made on the rapidity of the passage of crystalloid substances into the vascular and non-vascular textures of the body. It occurred to me that it might be possible to trace the passage of substances from the blood into the textures of the body by means of the spectrum-analysis, and with the assistance of Dr. Dupré some very remarkable results have been obtained.

THE long career of James Keir (born in Edinburgh on 20 September 1735, elected a Fellow of the Royal Society on 8 December 1785, died at West Bromwich on 11 October 1820) effectively covered the period of the scientific revolution out of which modern chemistry evolved. Keir himself played a significant part in that revolution, as writer, experimenter, and industrialist—and, by no means least, as a frequent ‘chairman’ at meetings of the Lunar Society of Birmingham, which he helped to hold together by his tact and force of character. Although there are frequent references to Keir in books and articles dealing with the period (1, 2, 3, 4, 5, 6, 7, 8), he remains relatively unknown, partly because he was overshadowed by men like Priestley and Watt, partly because he adhered too long to the phlogiston theory, and perhaps also because of his own modesty. A short account of his life, and an appreciation of his contributions to science and technology, may therefore not be out of place, particularly in view of the marked revival of interest in the Lunar Society in recent years.

The Subject

In a paper treating mainly on the structure of the Heliopora cœrulea , which was communicated to the Royal Society in the autumn of last year (1875), I gave a short account of the results at which I had arrived from the examination of two species of Millepora obtained at Bermuda and at the Philippines, and expressed my intention of further prosecuting the subject at the Sandwich Islands and Tahiti, should material be forthcoming. At Honolulu no Millepora was met with; and this form apparently does not occur at the Sandwich Islands, the water being too cold for it. At Tahiti a Millepora is very abundant on the reefs in from one to two feet of water, and is very conspicuous because of its bright yellow colour.

Saline Spring

On the 7th of January 1839, I communicated to the Royal Society of Edinburgh a pretty detailed account of the singular mineral and gas springs of Kissingen, in Bavaria, then much less known than at present to English travellers. I refer to this paper, printed in the Edinburgh New Philosophical Journal, April 1839, for the details of the most curious of these, a saline spring called Kunde-Brunnen, which was at that time regularly periodic; a copious and turbulent discharge of brine, mixed with torrents of carbonic acid gas, recurring six or eight times in the twenty-four hours. This phenomenon, exactly as described in my paper, appears to have continued with slight variation ever since, that is, for a period of twelve years, subject, however, to the variation formerly mentioned, that when the brine is actively withdrawn by pumps, for the manufacture of salt, the periods lengthen.

1. The late Mr Alexander Adie, optician, and Fellow of the Royal Society of Edinburgh, was so generally known to be a zealous and careful observer of meteorological instruments, that an attempt to combine the results deducible from his labours carried on (though with one long break) over more than forty years, cannot be otherwise than interesting.2. The plan of superintending the careful reduction of the thermometrical part of Mr Adie's registers occurred to me a long time ago, but circumstances prevented the execution of it until two or three years since, when, through the kindness of Mr Adie and his family, the whole of the manuscript observations, commencing with 1795, were put into my hands, and the Council of the Royal Society of Edinburgh provided sufficient funds for the employment of computers for reducing them.3. The work has proceeded with frequent interruptions, but is at length complete. Before I proceed to detail the particulars of the reductions and their results, I will give a short account of the earlier observations on the climate of Edinburgh which I have been able to trace, some of which perhaps have hitherto escaped notice.

Apparent Specific Heat

(33*.) In my paper on the Mechanical Action of Heat, published in the 1st Part of the 20th Volume of the Transactions of the Royal Society of Edinburgh, some of the numerical results depend upon the dynamical equivalent of a degree of temperature in liquid water. The value of that quantity which I then used, was calculated from the experiments of De la Roche and Bérard on the apparent specific heat of atmospheric air under constant pressure, as compared with liquid water.The experiments of Mr Joule on the production of heat by friction, give, for the specific heat of liquid water, an equivalent about one-ninth part greater than that which is determined from those of De la Roche and Bérard. I was formerly disposed to ascribe this discrepancy in a great measure to the smallness of the differences of temperature measured by Mr Joule, and to unknown causes of loss of power in his apparatus, such as the production of sound and of electricity; but, subsequently to the publication of my paper, I have seen the detailed account of Mr Joule's last experiments in the Philosophical Transactions for 1850, which has convinced me, that the uncertainty arising from the smallness of the elevations of temperature, is removed by the multitude of experiments (being forty on water, fifty on mercury, and twenty on cast iron); that the agreement amongst the results from substances so different, shews that the error by unknown losses of power is insensible, or nearly so; and that the necessary conclusion is, that the dynamical value assigned by Mr Joule to the specific heat of liquid water, viz.:—772 feet per degree of Fahrenheit, does not err by more than two or at the utmost, three feet; and therefore, that the discrepancy originates chiefly in the experiments of De la Roche and Bérard.
