This expedition was one of those organised by the Joint Per­manent Eclipse Committee of the Royal Society and Royal Astro­nomical Society, funds being provided from a grant made by the Government Grant Committee. The observers are indebted to the Great Indian Peninsular Rail­way Company for the carriage of the instruments at reduced rates between Bombay and Pulgaon, and for a considerable reduction of fares to the observers for this journey.

The expedition to which this report refers was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and the Royal Astronomical Society; it was supported by a grant made by the Government Grant Committee. Guelma was chosen for the site of the observations, as being an inland station between Sfax, which was selected for an expedition from the Royal Observatory, Greenwich, and Philippeville, which it was at first expected Sir Norman Lockyer would occupy. Guelma is 58 kilometres from Bona, 65 kilometres from Philippeville, 55 kilometres from the nearest coast of the Mediterranean Sea; it lies at a height of about 1200 feet above sea-level on the south side of the Valley of the Seybouze, amongst hills which range in height from about 3100 feet at 13 kilometres to the north, to about 4700 feet at 11 kilometres on the south, where lies the celebrated mountain, Mahouna, “the sleeping lady,” so called from the resemblance of its silhouette to the form of a woman.

This expedition was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and Royal Astronomical Society, funds being provided from a grant made by the Government Grant Committee. It was originally contemplated that the party should consist of Professor H. H. Turner and myself, and that we should occupy a station inland in Sumatra; but when the former found himself unable join in the expedition, it was decided not to appoint another observer in his stead, nor to fix upon the station to be occupied until there was an opportunity of learning about local conditions, on the spot.

This expedition was one of those organised by the Joint Permanent Eclipse Committee of the Royal Society and the Royal Astronomical Society, funds being provided from a grant made by the Government Grant Committee. The following were the principal objects which I had in view in arranging the expedition:— To obtain a long series of photographs of the chromosphere and flash spectrum, including regions of the sun’s surface in mid-latitudes, and near one of the poles.

The Joint Committee have requested me to make the following brief report on the observations of the Eclipse. This will be followed shortly by a more complete report. The Joint Committee was formed early in 1892, a grant of money was obtained from the Government Grant Fund of the Royal Society, and preparations were at once begun. After due consideration, it was decided to send out two observing expeditions, one to Fundium, on the Salum River, in Senegambia, and one to Pará-Curu, in the Province of Ceará, in the northern part of Brazil. With the exception of the work undertaken by Professor Thorpe, the whole of the observations were photographic. Three classes of work were undertaken at each station.

1. This expedition was organised by the Joint Permanent Eclipse Committee of the Royal Society and Royal Astronomical Society, funds being provided from a grant made the Government Grant Committe. The Government of India made excellent arrangements for the party, and the Surveyor-General of India with the staff of his Department rendered great service in selecting a site, clearing the jungle, establishing a camp, erecting the instruments, and in giving every assistance in the observations, for all of which the observers desire to tender their thanks.


1. General Arrangements . The expedition to observe the total solar eclipse of 1911, April 28, was organised by the Joint Permanent Eclipse Committee, the expenses being defrayed by the Government Grant Fund. Of the few islands in the South Pacific crossed by the track of the moon’s shadow during totality, Vavau, one of the northernmost group of the Tonga or Friendly Islands, was the most suitable for observing the eclipse, the duration of totality being computed at 217 seconds, and there being a reasonable prospect of good weather. The programme of observations consisted of photographs of the corona on a large and relatively small scale for coronal detail and extension of the streamers, and photographs of the spectrum of the corona and of the lower chromosphere. For these purposes the expedition was furnished with a 4-inch photographic lens of 20 feet focal length, kindly lent by the Council of the Royal Irish Academy, and the 4-inch Dallmeyer “Abney” lens of 34 inches focal length. For the spectrum of the corona Prof. Newall kindly lent the quartz spectroscope of four prisms, presented to the Cambridge Observatory by Major Hills, in order further to investigate the ultra-violet spectrum. The fourth instrument was made up of a large 7-inch prism of 40° in combination with a 6-inch Dallmeyer portrait lens of 30 inches focal length, This objective prismatic camera gave a short but very bright spectrum, 4⋅5 cm. from H α to H ζ . The intention was to investigate the red end of the coronal spectrum on dyed plates, and incidentally to photograph the flash spectrum. The members of the expedition were Father Cortie and Mr. W. McKeon, from the Stonyhurst College Observatory, and Father E. Pigot, Director of the Observatory of St. Ignatius’ College, Rivervievv, Sydney, N. S. W., who also acted as agent for the expedition in Sydney, in the preparation of huts to cover the instruments, and in the gathering of materials for building the piers for the foundations. The Admiralty gave instructions that H. M. S. “Encounter” should convey the observers and the instruments from Sydney to Vavau and back, and that every assistance should be rendered to the expedition in the erection of the instruments and in the observations. The expedition is greatly indebted to Captain Colomb, and to the officers and men of the “Encounter,” for their enthusiastic co-operation in the work of the expedition.

Carriacou is a small island situated about twenty miles to the north of the island of Grenada, the chief of the Windward group, and furnished an excellent site for the observation of the last solar eclipse. Most of the observers sent by the Eclipse Committee of the Royal Society to the West Indies in August of last year remained at Grenada, or on the small islands in its immediate vicinity, whilst Mr. Maunder and myself occupied the more distant northern station, where the totality was slightly diminished in duration. The work proposed for Mr. Maunder was to secure a series of photographs of the corona, with exposures of 40s. and under, and also to obtain two photographs of the spectrum of the corona with the longest exposures possible.


The following preliminary report deals briefly with the observations made during my residence in Montserrat from 24 March to 24 July, 1936, and with the main conclusions to be drawn from them. The Royal Society Expedition is greatly indebted to the representatives of His Majesty’s Government, to His Excellency Sir Gordon Lethem, Governor of the Leeward Islands, and to the Commissioner and Acting Commissioners of Montserrat for much kindness and assistance. We are also indebted for the most generous and liberal assistance rendered to the expedition by officials, representatives of organizations, and private individuals in ways too numerous to be described in detail. The members of the Expedition had the fullest support from the Government and the citizens of the island.

The development of government participation in the support of research is one of the most significant characteristics of nineteenth-century science. As public money became available for science, the social framework of research underwent a profound transformation. This process of transformation is not easy to define, but the response of scientific societies and institutions sometimes provides significant clues.

In the month of August, 1897, I was invited by the Joint Permanenta Eclipse Committee to take part in observing the total solar eclipse which occurred in India on 22nd January of the present year. The preparation of the equipment, which will be described further on, was at once proceeded with, and by the sanction of the Univer­sity authorities and the Secretary for Scotland I was granted the necessary leave of absence from the University and the Royal Observatory.
