THE U.S. Weather Bureau has issued its meteorological chart of the Great Lakes for the winter of 1903-4. This was the coldest winter in the lake region that has been experienced since the beginning of the Weather Bureau observations in 1871. Freezing temperatures commenced about the middle of November. The climax was reached in February, when the mean monthly temperature ranged about 10° below the normal in all districts. On Lake Superior the ice-fields did not disappear from the eastern portion until the last week in May, 1904. Several interesting photographs are given of vessels and ferries forcing their way through apparently impassable masses of ice as soon as a thaw set in. When navigation is practicable storm warnings are displayed by day and night, and at almost all stations a chart is issued showing the weather conditions at Sh. a.m. daily (except Sunday); masters of vessels are invited to obtain these charts, or any other information in connection with the weather, at any of the Weather Bureau offices.
A NEW general theory of errors has been contributed to the Proceedings of the American Academy of Arts and Sciences, xi., 3 (August), by Mr. William Edward Story. The author's object has been to develop the theory in such a way as to avoid the usual assumptions, the legitimacy of which, as approximations, may be questioned. It is claimed that the present theory is based upon such simple principles as will be generally admitted to be necessary for the mathematical treatment of any theory. The fundamental assumptions are as follows :-Possible errors form a practically continuous sequence from a certain lower limit to a certain upper limit. The probability that the error of an observation lies between x and x+dx, where dx is infinitesimal, is $(x)dx, where $(x) is an analytical function of x, developable by Taylor's theorem throughout the whole range of possible error. The probability that the error lies between given limits is independent of the unit of measurement.
APFENDIX iii. of a report upon the basin of the Upper Nile, with proposals for the improvement of that river by Sir Waliam Garstin, contains an interesting account of the variations of level of Lake Victoria Nyanza contributed by Captain H. G. Lyons, the director of the Survey Department of Egypt. This lake has a water surface of about 68,000 square kilometres, and is situated about 1129 metres above sea level. It is believed to be of shallow depth, and lies for the most part of the year in the region of the equatorial rain and cloud belt, the excess water draining off at the Ripon Falls by the Victoria Nile. After reference to the geology and climate of the region, a brief historical sumfrary is given of the early lake levels as observed by travellers and others visiting or residing by it; this is followed by a detailed study and discussion of the various gauges. Some of the results obtained are as follows :The annual oscillation of the lake is from 0.30 metre to 490 metre. Between 1896 and 1902 there was a fall of 76 cm, in the average level, since followed by a rise of 56 cm. The epochs of high and low levels are given 25:-1878, high level ; 1880-90, falling level ; 1892-95, temporary high level; 1896–1902, falling level ; 1903, rising level.
ATTENTION has already been directed in these columns to the important innovation introduced into this country by the Drapers' Company in granting a sum of 1000l. to University College, London, for the furtherance of research in applied mathematics. No better testimony to the value of this grant could be adduced than is afforded by a reference to the pages of Nos. 1 and 2 of the technical series of the Drapers' Company Research Memoirs, edited by Prof. Karl Pearson. In the first of these Mr. E. S. Andrews discusses the stresses in crane and coupling hooks by means of the theory of elasticity, and describes experimental tests in verification of his theory. The present investigation shows not only that the existing theory is unsatisfactory, both theoretically and practically, but that improvements can well be made in existing types of hooks by following lines laid down in the paper. In the second paper Mr. L. W. Atcherley directs attention to certain very serious defects in the theory of masonry dams. It is shown that the stresses across vertical sections of a dam are far more important than those across horizontal sections, and that in many existing dams not only do shearing stresses exist in the vertical sections which are far in excess of any considered safe by engineers, but considerable tensile stresses also occur, which form a serious source of danger. These two papers are fitting illustrations of the many important practical problems now awaiting solution, which could be solved at a very small cost by the provision of further endowments for mathematical research.
We have received from Mr. W. J. Brooks, 33 Fitzroy Street, W., some of his patent flexible curves and a parabolic curve. One of the former is a strip of celluloid with Tags at intervals along its length; when placed on paper it can be bent to any desired curve, the fingers being placed on the tags to keep the strip in position; the strip does not yield under the pen. A second form (pattern B) has a Steel strip and is self-clamping and reversible; this ingenious device maintains the steel strip in any position by means of stiff-hinged linkwork attached to metal tabs. The shape of any curve thus formed by this strip can be transferred from one drawing to another, a desirable advantage to many workers. A third and longer form (pattern C), also sell-clamping and reversible, has been designed for such special purposes as are required by ship and boat builders, but it will have a much wider field of adaptation, such as, for instance, in the construction of interpolation curves for wave-lengths in spectroscopic work, &c. This pattern, which can be obtained from one foot up to any length, consists of light wooden cross-bars hinged to tabs fixed to a steel strip. The strips slide through brass springclamps, and are thus held tight against a stout wooden bar running the length of the curve. Several patterns and sizes for all the curves are obtainable, and they may be
