On the Quantities of Rain received in Gauges at unequal Elevations upon the 

 Ground. By Professor Phillips, F.R.S. 

 The author, referring to three reports which he had already presented, observed 

 that the results arrived at, on York Minster, on the Yorkshire Museum, and on the 

 ground at York, for three years, appeared to require no repetition, and that the rea- 

 soning on the results having been generally accepted, he should have thought it un- 

 necessary to recal attention to the subject, unless he had some new facts to com- 

 municate. On duly estimating the force of the objections which had been, or might 

 have been, urged against the former experiments, such as the influence of local eddies 

 and currents of wind about the Minster and Museum, and such buildings generally. 

 Professor Phillips resolved to establish a registration of gauges raised into the open 

 air, to various heights, independent of buildings. He had carried on trials of this 

 kind at intervals for more than five years, and after using globular gauges, and 

 various modes of measuring the rain collected, he had finally employed for the last 

 two years, funnel gauges, emptying themselves into reservoirs placed in the ground. 

 Thus some particular difficulties were obviated, and a consistent tally of results ob- 

 tained. In 1843, from January 9 to October 14, he had obtained registrations of 

 the gauges almost continuously, and in 1844, a similar series from January 1 to 

 September 2, was recorded for him by Mr. Cooke. The gauges are five in number, 

 at I5, 3, 6, 12, and 24 French feet above the ground. The registrations for the 

 two periods are as under : 



On these facts the author forbore to comment, having the intention to vary the 

 experiments. 



On Simultaneous Barometrical Registration in the North of England. 

 By Professor Phillips, F.R.S. 



Following out in a limited district the plans of contemporaneous hourly registra- 

 tion, which had been prosecuted by Sir J. Herschel and M. Quetelet for larger 

 areas, the author found the means to combine observations on the barometer, at- 

 tached thermometer and direction of wind, for twenty-four hours in each month, at 

 nine stations in the north of England, viz. Kendal, Shields, Whitby, Scarborough, 

 Hull, York, Sheffield, Birmingham, Manchester. The observations of five of these 

 stations for six months had been approximately discussed, viz. those of Shields, 

 Hull, York, Sheffield and Birmingham, and the results projected in diagrams. They 

 showed, — 1, the remarkable general accordance in the forms of the contempora- 

 neous curves at all the stations ; 2, the various limits of the deviations from uni- 

 formity, never amounting at any two stations to above one-twentieth of an inch ; 

 3, the passage of waves of greater or less pressure in directions nearly correspond- 

 ing to the path of the wind at the time, and with velocities which appear propor- 

 tioned to the general movement of the atmosphere at the time, viz. twenty to forty 

 miles an hour. 



On the Curves of Annual Temperature at York. By Prof. Phillips, F.R.S. 



The author stated that the data which he had collected extended over long periods, 

 one series including twenty-five years' registration of the barometer, thermometer, 

 and ancient hygrometer, and that they had been so far discussed as to give interesting 

 results, and that on a future occasion he hoped to present the complete analysis and 

 inferences. 



On the Irregular Movements of the Barometer. By T. Hopkins. 

 Mr. Hopkins maintained that the irregular movements of the barometer arise, not
