CAPTAIN WILLIAM BLIGH,R.N., HYDROGRAPHIC SURVEYOR

Abstract

The name of Bligh will for all time be associated with the incident of the Bounty Mutiny during his first mission of transporting the Bread Fruit to the West Indies. This was, however, but one episode in his eventful career in the Royal Navy. At various times he took part in scientific expeditions and voyages of discovery, commanded fighting ships, etc. Between 1797 and 1803 he fulfilled the duty of hydrographic surveyor and carried out a number of surveys of limited areas in the British Isles and adjacent coasts of Europe. These examinations, of which the River Humber, Dublin Bay, Dungeness and the mouth of the River Schelde are the most detailed, were valuable additions to hydrographic knowledge, coming as they did before organized surveying as we know it today had fully established itself.

PAPER CONTROL AND THE E.S.R.

Abstract

Readers will notice that the weight of the paper used in this issue of the Review has been substantially reduced when compared with the weight of that used in previous issues. The reason for this is the necessity for further economy in the use of paper. A reduction in the number of pages from sixty-four to forty-eight was made in the January and April numbers, but even these savings are not sufficient in themselves and commencing with the October issue the number of pages will have to be reduced still further from forty-eight to forty. However, by reducing the sizes of the margins, so as to give an increase in the actual printing area, it will be possible to include more printed matter on each page than appears at present. In addition, it is proposed no longer to print the whole of the Colonial Office List of Recent Appointments and Promotions in the Colonial Service, but only to include those parts of it that are of immediate interest to surveyors. As a result of these measures, it is estimated that the total amount of matter to appear in the forty pages will be almost the same as that now included in forty-eight.     

Signal and noise in S.L.R. data

The problem of judging on model deficiency in S.L.R. data treatment is considered. In particular the correlation analysis of residuals of adjusted orbits is used to show the presence of unmodelled signals. This analysis seems suitable at least for a proper preprocessing of S.L.R. data, in the sense of being an efficient procedure of outliers rejection.

THE LATE CAPTAIN McCAW'S CONTRIBUTIONS TO THE E.S.R.

Abstract

The volume of this Review which has just been completed commenced with a memoir of the first Editor, the late Captain G. T. McCaw, C.M.G., O.B.E., M.A., who died in October 1942, and, in view of his great services to the Review and to the survey world in general, it is thought to be not in-appropriate that this, the first number of a new volume, should contain a list of his contributions to the Review. The power and versatility that they display are remarkable.
