The object of the present ( i. e. the Eleventh) Number of the Contributions to Terrestrial Magnetism is the completion of the great national undertaking, the Magnetic Survey of the South Polar Regions of the Globe, corresponding to the Epoch 1840—1845. The Survey originated in a Report presented to the British Association for the Advancement of Science at the Liverpool Meeting in 1837, entitled “ On the Variations of the Intensity of the Earth’s Magnetic Force observed at different points of the Earth’s Surface:” copies of this Report were widely circulated amongst the Members of the Association previously to the Meeting at Newcastle in the following year, 1838; and having received a favourable notice in the opening address of the then Secretaries of the Association, Dr. George Peacock and Sir Roderick Murchison, resolutions were passed by the General Committee, which are printed in pages xxi and xxii of the “Annual Report of the Proceedings at Newcastle in August 1838.” These resolutions having been formally communicated to the Royal Society, a joint committee of the two scientific institutions was appointed to bring the subject of the equipment of a naval expedition for magnetic observations in the Arctic Seas under the consideration of Her Majesty’s Government. A single sentence from the address of this Committee may be cited as evidencing the spirit in which the joint application of the Royal Society and of the British Association was made to Her Majesty’s Government.

This number of the Contributions of Terrestrial Magnetism contains the completion of the Magnetical Survey of the South Polar Regions, undertaken by Her Majesty’s Government in 1840-1845 at the joint instance of the Royal Society and the British Association for the Advancement of Science. The observations themselves, and their provisional discussion, have already been given in the previous numbers, V., VI., VIII., and X. of the Contributions. The present number contains a general review of the whole survey, and is accompanied by three maps, which have been prepared, with the permission of the Hydrographer, Captain Richards, R. N., E. R. S., under the careful superintendence of the Assistant Hydrographer, Captain Frederick John Evans, R. N., F. R. S., one map being allotted to each of the three magnetic elements, viz. the Declination, Inclination, and Intensity of the Magnetic Force. In these maps the Isogonic, Isoclinal, and Isodynamic lines have been drawn, by the author of the paper, conformably with the observations around the circumference of the globe between the parallel of 30° S. and the South Pole. The paper also contains Tables, prepared with a view to the revision of the calculations of Gauss’s 'Allgemeine Theorie des Erdmagnetismus.’ They give the values of each of the three magnetic elements at the intersections of every fifth degree of latitude between 40° of south latitude and the South Pole, and every tenth degree of longitude between 0 and 360°.

I am indebted, for the opportunity of laying the following observations and their discussion before the Royal Society, to the kindness and courtesy of Chamberlain General Adjutant Irminger, of the Royal Danish Navy, who undertook (in 1862) to have Tidal observations made by the Missionaries and Government officers at certain stations on the coast of Greenland, for the purpose of completing the observations, on the Tides of the Arctic Seas, made by several officers of Her Majesty’s Navy during the search for Sir John Franklin ; some of which I have already laid before the Society, in Parts I. and II. of these papers; of others I hope to be able to complete the discussion, and to forward them in due course to the Royal Society. The observations recorded and discussed in the present paper were made in 1863-64, at Frederiksdal, near Cape Farewell, by Missionary Asboe, to whom and to Admiral Irminger I beg leave to return my warmest thanks for their uniform courtesy and attention to a request proceeding from a total stranger.

The language of science has been extensively studied by linguists and rhetoricians – as a distinctive register, as a set of genres that students and academics need to master, and as a discourse of powerful social institutions. Most of these studies have been synchronic, focusing on the structures or styles of more or less contemporary texts, particularly research articles. But if we rely on such studies, we may tend to reify some features of text (such as the Introduction–Methods–Results–Discussion form, or the tendency to passive constructions and nominalizations) as inevitable features of scientific communication. We may also treat scientific institutions – such as the lines between disciplines, or between professionals and amateurs – as given by the subject matter, rather than seeing them as changing and as constituted in part by their communicative practices.

Containing a Magnetic Survey of a considerable portion of the North American Continent. From the moment that the fact was known, that the locality of the maximum of the magnetic Force in a hemisphere is not coincident, as was previously supposed, with the locality where the dip of the needle is 90°, researches in terrestrial magnetism assumed an interest and importance greatly exceeding that which they before pos­sessed; for it was obvious that the hypothesis which then generally prevailed regard­ing the distribution of the magnetic Force at the surface of the globe, and which had been based on a too-limited induction, was erroneous, and that even the broad out­ line of the general view of terrestrial magnetism had to be recast. The observations on which this discovery rested, (being those which I had had an opportunity of making in 1818, 1819 and 1820 within the Arctic Circle, and at New York in 1822,) were published in 1825*; they constituted, I may be permitted to say, an important feature in the views, which led the British Association in the year 1835 to request that a report should be prepared, in which the state of our knowledge in respect to the variations of the magnetic Force at different parts of the earth’s sur­face should be reviewed, and, as is customary in the reports presented to that very useful institution, that those measures should be pointed out which appeared most desirable for the advancement of this branch of science. In the maps attached to the report, the isodynamic lines on the surface of the globe were drawn simply in conformity with observations, and unmixed with hypothesis of any sort. The obser­vations collected for that purpose were not those of any particular individual or of any single nation, but embodied the results obtained by all persons who up to that period had taken part in such researches, subjected to such amount of discussion only as conveyed a knowledge of the modes of observation severally employed, and reduced the whole to a common unit.


1. In this paper we describe a long series or experiments on the electrification of air and other gases, with which we have been occupied from May, 1894, up to the present time (June, 1897). Some results of our earlier experiments, and of preliminary efforts to find convenient methods of investigation, have from time to time been communicated to the Royal Society, the British Association, and the Glasgow Philosophical Society. 2. The method for testing the electrification of air, which we used in our earliest experiments, was an application of the water-dropper (long well-known in the ordinary observation of atmospheric electricity). Its use by Maclean and Goto, in 1890, led to an interesting discovery that air in an enclosed vessel, previously non-electrified, becomes electrified by a jet of water falling through it. An investigation of properties of matter concerned in this effect, related as it is to the “development of electricity in the breaking up of a liquid into drops,” which had been discovered by Holmgren as early as 1873, and to the later investigations and discoveries described by Lenard, in his paper on the “Electricity of Waterfalls,” forms the subject of 25-37 of the present communication.

The study of marine life from the bottom of Arctic and sub-Arctic seas has long been a topic of scientific interest, and such work represents an important part of contemporary biological research in the polar regions. Contributions to this field have been made through the collective efforts of investigators from many nations over the years and include findings of considerable significance for life science studies as a whole, as well as for specific polar problems. Together with contemporary research on the pelagic and planktonic biota of northern waters, current work on the bottom fauna (benthos) offers much potential for developing our fundamental knowledge of biological processes in the Arctic seas.

This research was commenced three years ago, and has been carried on intermittently in the intervals of other work. Preliminary reports on some of our results have been laid before the British Association at the Ipswitch, Liverpool, Toronto, and Bristol meetings, and a short paper on one section of the subject was communicated to the Royal Society and printed in the 'Proceedings' last year, In the present paper we give a full account, with illustrations, of the detailed evidence upon which our various conclusions are based.

1. Relation to Magnetic Survey.—After being engaged for sometime, in conjunction with Professor Thorpe, upon the Magnetic Survey of the United Kingdom, Professor A. W. Rücker, F.R.S., put forward his theory of Terrestrial Magnetism.In connection with this theory, it was desirable to determine the permeabilities of various rocks, both at ordinary and at high temperatures.2. The investigation which forms the subject of the present paper is an instalment in this direction. Professor Rücker proposed this undertaking and indicated the plan to be followed. It was then carried out under his supervision at the Royal College of Science, London.

The Committee would commence their Report with the expression of heir heartfelt regret at the decease of Mr. J. P. Gassiot, who had been, ince 1851, among the most active Members of the successive Kew Committees, first of the British Association, and latterly of the Royal Society, Mr. Gassiot had not only devoted freely to the management of Kew Observatory a large portion of his valuable time, but also had, in 1871, most munificently endowed the establishment with the sum of £10,000 Italian rrigation Stock, for the purpose of maintaining in a state of thorough efficiency the self-recording observations in terrestrial magnetism and in meteorology. Committee .— The Committee is constituted as follows :— General Sir E. Sabine, K. C. B., Chairman . Mr. De La Rue, Vice-Chairman . Capt. Evans. Mr. E. Galton. Vice-Adm. Sir G. H. Richards. The Earl of Rosse. Mr. R. H. Scott. Lieut.-General W. J. Smythe. Lieut.-General Strachey. Mr. E. Walker. Mr. R. H . Scott, at his own request, has been for the future relieved of the duties of Hon. Secretary, which he has performed ever since the Observatory came under the management of the Royal Society, and the duties of that post will be in future discharged by the Superintendent.

The first part of the author’s researches on the Tides of the Arctic Seas was forwarded to the Royal Society in November 1861, and contained the discussion of the Diurnal Tides of Port Leopold. In the present communication the Semidiurnal Tides of the same port are discussed, and the following results obtained. The eccentricity of the moon’s orbit is calculated from the parallactic inequality, and found to be 0·5303.
