five o'clock P.M., wind N.E. ; barometer, 29'750; Fahr. thermometer at the mouth 

 of the well, 51°. Sounded the well with a cord, to which was suspended a self- 

 registering thermometer. At 100 feet deep, 57° ; at 200, the same. 



On Tuesday, September 24, five o'clock p.m., wind N.E. ; barometer, 29*550 ; Fahr. 

 thermometer at the mouth of the well, 5(j° in the shade ; at 100 feet deep, 57° ; at 200 

 feet, the same. The water at the bottom of the well, about 3284- feet from the top, 

 50°. 



On Wednesday, September 25, at half-past two p.m., wind N.E. , but very gentle ; 

 barometer, 29"710; Fahr. thermometer at the mouth of the well, 58°; at 150 feet 

 deep, S. R. therm., 56° ; at 200 feet, the same ; just above the surface of the water, 

 about 327 feet, 50° ; water, 49°. 



Atthesame time the water in a wide shallow pond near the well, 57° ; in a pump 

 drawn from a cistern filled with rain-water, fourteen feet deep, 51°. 



It appears from the last sounding, that the temperature in the shaft of the well 

 is regulated by that of the water. Shaft, 57° ; water, 50° ; shaft, 56° ; water, 49° ; 

 being 1° minus in both ; difference, 7°. 



If the reported depth of the well be 348 feet deep, the water must be 194- feet. By 

 the cord it was found to be 329^- feet from the top ; and from the wet end of the 

 cord, which was supposed to have been at the bottom, having measured 19t feet 

 + 328i = 348 feet. 



Singular Appearance of a Thunder Storm on Yorkshire Wolds, Jult/ 5, 184:3. 

 By the Rev. T. Rankin. 



On July 5, 1843, about two o'clock p.m., the barometer fell from 29'270 to 29*240. 

 Thermometer Fahr. stood at 71°, the highest point for that month. Between four 

 and five o'clock the horizon in the S.W. began to darken ; about six distant thunder 

 was heard ; betwen six and seven the dark clouds approached the Wolds, the thun- 

 der was heard in a continued rolling and growling noise, and the sportive lightning 

 variegated the scene. About eight o'clock the spectacle was sublime and terrific. 

 Volumes of gaseous matter, like the smoke from a park of artillery, rolled along the 

 higher grounds to the N.E. Behind this was a lengthened black cloud rising in an 

 inclined manner, forming an angle of above 45° with the horizon. As the thunder 

 became louder the lightning became more vivid. About nine it reached the summit 

 of the Wolds, preceded by a violent rush of wind ; then the broad sheet lightning, 

 followed by loud peals of thunder. Torrents of rain descended in consequence, which 

 terminated iu hail and large pieces of ice. About ten o'clock the lightning struck a 

 cottage chimney at North Dalton, and descending, shivered a large splinter from the 

 beam upon which it rests, about a quarter of an hour after the family had retired. 



Description of an improved Anemometer. By James Thomas Goddard. 



Having after the labour and study of several months succeeded in the construction 

 of a meteorological instrument, designed for keeping an accurate register of the total 

 force of the wind which passes over any station in a given time, such as twenty-four 

 hours, as well as noting the direction, the author offers a slight description of its 

 object and nature. The object sought in the valuable and ingenious anemometer of 

 Mr. Osier of Birmingham, as is well known, is a complete picture of the force and 

 direction of the wind for each day, noting the time to a minute or two of every 

 change in the force and direction of the aerial currents ; and for this purpose it is 

 the most perfect and elegant instrument ever placed in the hands of the meteoro- 

 logist. 



The instrument of mine is however intended to show the collective velocity of the 

 wind, or rather the number of miles of air which pass the vane during the twenty- 

 four hours, as well as the respective directions. By this means, by simply reading 

 off the daily results (without calculation) and laying them down on a map of the 

 country, we are informed of the distance and extent to which a wind penetrates into 

 the interior of a large country, thereby giving strictly predictive results ; at the same 

 time giving every facility to the investigation of the causes which stop the progress 

 of a wind, or change its direction in the interior of the country, as well as finding
