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.

A new rare species of deepwater Branchiostegus is described from two specimens collected from Bayangas, Laiya, Philippines(130 38.5’ N, 1210 25.6’ E). A total of four specimens were caught by hook and line in 2009 and 2011 between 210–220 m overa rocky-sand bottom, only two were preserved. The species may also be endemic to the Philippines and inhabit burrows as dothe other known species of this genus. The combination of the following characters distinguish the new species from its conge-ners: prominent dark predorsal ridge bordered by bright yellow-orange background (only B. semifasciatus from West Africahas a more prominent and dark predorsal ridge, but the ridge has no underlying orange-yellow colour), a great body depth (28–29% SL; other species of Branchiostegus, usually 27% SL) longer head length (30–31% SL; other species of Branchiostegus,usually 28%), greater head depth (26–27% SL; other species of Branchiostegus, usually 26% SL); long pre-dorsal length (35%SL; other species of Branchiostegus, usually 32% SL), and distinctive body, head and caudal fin colouration; skin over dorsal tips of branchiostegals characteristically bright yellow. A brief discussion of the status of tilefish systematics is included.

Oxygen Gas

The author, having observed the properties of oxymuriatic gas to be different in consequence of its being prepared in different modes, was endeavouring to determine the nature of these differences, and the causes on which they depend, when he discovered the very singular compound which is the subject of the present paper. For the formation of this compound, he pours a small quantity of dilute muriatic acid upon a large quantity of hyperoxymuriate of potash. A gas is then disengaged, which is capable of being absorbed by water, but may be collected over mercury. It is of a bright yellow colour, approaching to orange, and has nearly the specific gravity of oxymuriatic gas. It often explodes while collecting, in consequence of heat gene­rated; and it may always be made to explode by the heat of the hand, with instantaneous extrication of heat and light. After explosion the gas is found to oceupy about one sixth part more hulk than before. From the gas so exploded, oxymuriatic gas may be absorbed by water, and there remains about one third part of oxygen.

I have the honour to lay before the Royal Society a short account of some theoretical researches on the daily change of the temperature of the air, made by me in 1895, and published to a certain extent in the Nova Acta der kaiserlich Leopoldinisch-Carolinischen Academie der Naturforscher, Band lxvii., No. 2. Some more recent investigations on the subject, chiefly dealing with the physical point of view of the problem, have not yet been published, but seem to me of such importance as to justify me in presenting a brief sketch of them to the Society in this paper.The history of the mathematical aspect of the problem can be traced back as far as the middle of the last century, when Lambert made the first attempt at investigating the relation between solar and terrestrial radiation and the temperature of the atmosphere. He was succeeded by a great number of famous mathematicians and meteorologists, whose labours, however, though they contributed considerably to our knowledge of certain parts of the question, have not been rewarded, it must be said, with any sufficient result; so that a satisfactory solution of the problem by means of theoretical investigations has been eventually considered impossible, at least in some quarters.There can be no doubt that, in a problem like this, an immense number of different errors affect the principal conditions of the propagation of heat, which conditions are supposed to be the causes of the observed changes of the temperature.

The detailed structure of the spiracles in the Ixodoidea has hitherto received little or no attention at the hands of zoologists; at the same time, these organs are sufficiently extraordinary to make it a matter of surprise that, so far as our knowledge of the literature goes, not one of the numerous contributors to the subject of tick anatomy has found it worth while to undertake a complete description or to publish figures to illustrate it. Batelli (1891) gives a short account of the structure of the spiracle of a tick, presumably Ixodes ricinus, with a single figure, but with this exception we have been unable to find any further information on the subject.

During the progress of the investigations which I have from time to time had the honour of bringing under the notice of the Royal Society, I have again and again noticed the apparent disappearance of gases inclosed in vessels of various materials when the disappearance could not be accounted for upon the assumption of ordinary leakage. After a careful examination of the subject I found that the solids absorbed or dissolved the gases, giving rise to a striking example of the fixation of a gas in a solid without chemical action. In carrying out that most troublesome investigation, the crystalline separation of carbon from its compounds, the tubes used for experiment have been in nine cases out of ten found to be empty on opening them, and in most cases a careful testing by hydraulic press showed no leakage. The gases seemed to go through the solid iron, although it was 2 inches thick. A series of experiments with various linings were tried. The tube was electro-plated with copper, silver, and gold, but with no greater success. Siliceous linings were tried fusible enamels and glass—but still the' tubes refused to hold the contents. Out of thirty-four experiments made since my last results were published, only four contained any liquid or condensed gaseous matter after the furnacing. I became convinced that the solid matter at the very high pressure and temperature used must be pervious to gases.

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 papers in this symposium form the proceeding of the Royal Society’s Discussion Meeting held in March 1993. As co-organizers and editors, we trust that we have put together a timely, enterprising and enlightening volume which provides a fitting tribute to Alan Williams. It was Alan who first promoted to the Royal Society the subject of CD4 as a topic for one of the Society’s Discussion Meetings and who agreed to be cast in the role of organizer. After Alan’s untimely death, as coorganizers we were given the choice of proceeding with the meeting or not, and it was decided to proceed as a memorial to Alan. We are certain that it was exactly what Alan would have wanted us to do.

I have for some time entertained an opinion, in common with some others who have turned their attention tot he subject, that a good series of observations with a Water-Barometer, accurately constructed, might throw some light upon several important points of physical science: amongst others, upon the tides of the atmosphere; the horary oscillations of the counterpoising column; the ascending and descending rate of its greater oscillations; and the tension of vapour at different atmospheric temperatures. I have sought in vain in various scientific works, and in the Transactions of Philosophical Societies, for the record of any such observations, or for a description of an instrument calculated to afford the required information with anything approaching to precision. In the first volume of the History of the French Academy of Sciences, a cursory reference is made, in the following words, to some experiments of M. Mariotte upon the subject, of which no particulars appear to have been preserved. “Le même M. Mariotte fit aussi à l’observatoire des experiences sur le baromètre ordinaire à mercure comparé au baromètre à eau. Dans l’un le mercure s’eléva à 28 polices, et dans Fautre l’eau fut a 31 pieds Cequi donne le rapport du mercure à l’eau de 13½ à 1.” Histoire de I'Acadérmie, tom. i. p. 234. It also appears that Otto Guricke constructed a philosophical toy for the amusement of himself and friends, upon the principle of the water-barometer; but the column of water probably in this, as in all the other instances which I have met with, was raised by the imperfect rarefaction of the air in the tube above it, or by filling with water a metallic tube, of sufficient length, cemented to a glass one at its upper extremity, and fitted with a stop-cock at each end; so that when full the upper one might be closed and the lower opened, when the water would fall till it afforded an equipoise to the pressure of the atmo­sphere. The imperfections of such an instrument, it is quite clear, would render it totally unfit for the delicate investigations required in the present state of science; as, to render the observations of any value, it is absolutely necessary that the water should be thoroughly purged of air, by boiling, and its insinuation or reabsorption effectually guarded against. I was convinced that the only chance of securing these two necessary ends, was to form the whole length of tube of one piece of glass, and to boil the water in it, as is done with mercury in the common barometer. The practical difficulties which opposed themselves to such a construction long appeared to me insurmount­able; but I at length contrived a plan for the purpose, which, having been honoured with the approval of the late Meteorological Committee of this Society, was ordered to be carried into execution by the President and Council.
