320 Mr. Howard's Meteorological Journal. [Oct. 1818. 



Ninth Month. — I. Lowest temperature on the ground 44°. This morning from 

 two to three it thundered and lightened much to the SE: thunder clouds prevailed, 

 a.m.: wind SE, and a little rain : a slight shower again at night, and much dew 

 after it: the hygrometer advanced to 80°. 2. After large Cirri, Cumulostratus, 

 which inosculated about sun-set with a scanty Cirrocumulus. 3. A mixed sky, with 

 a slight driving shower at evening: cloudy night. 4. A sweeping rain, early: 

 hv°Tometer, 80° at six, a.m. : much hollow southerly wind : Cirrocumulus, followed 

 bv ill-defined Cimis with Cumulus; and about five, p.m. a. Nimbus, shaped like a 

 low, circular hay-rick, with a capped Cumulus by its side, on the NE horizon. 

 5. Much rain, for the most part small and thick. 6. Wet, cloudy morning : very 

 turbid sky : hygrometer at 80° : calm air : in the evening, inosculation of Cumulus 

 with Cirrocumulus ; after which frequent lightning between nine and ten, p.m. 

 7. Morning grav, with Cirrocumulus : sunshine followed, with inosculation of Cu- 

 mulus and Cirrostratut. 8. Large Cirri, with fliecy Cumuli: the latter attached 

 themselves in their passage to the smoke of the city, and appeared to disperse 

 downwards into it. Thunder clouds followed this appearance, and a smart storm 

 passed in the S, from W to E, about five, p. m. : the crown of the nearest Nimbus 

 reached our zenith, and we had a few drops ; while it rained hard, with a bow in 

 the cloud, within two miles of us. 9. Heavy Cumulostratus : and showers, p.m. 



10. Fine breeze, with Cumulus and Cirrus; the latter survived the sun-set, and was 

 kindled with flame colour passing to red: calm at Bight, with hygrometer 45°. 



11, 12, 13. Chiefly Cumulus, and Cumulostratus by inosculation : some fine group- 

 ing of the clouds at intervals : large Cirri at the conclusion. 14. A large meteor 

 seen passing northward: windy night. 15. Cloudy, windy: hygrometer, 75°: 

 ■wet, p.m. 16. Much dew : a rapid propagation of Cirrus from the S, followed 

 by Cianulostratus and showers : during a heavy shower about nine, p.m. it thun- 

 dered in the N W : the barometer stationary great part of these two days at 29*60 

 inches. 17 — 20- Windy at intervals, with Cirrostratus, turbidness, and driving 

 rains. 21. Much wind, with showers: the sky turbid, and streaked with Cirro- 

 stratus, in a direction frqni SE towards N\V : calm night. 



RESULTS. 

 Wind for the most part Westerly, and moderate. 



Barometer: Greatest height 30-30 inches. 



Least 29-32 



Mean of the period 29-860 



Thermometer : Greatest height 80° 



Least 39 



Mean of the period 58-68 



Mean of the Hygrometer 54 



Evaporation 2-33 inches. 



Rain 1-71 inches. 



The rains of this period, though absorbed by the parched ground as by a sponge, 

 have completely restored vegetation in our meadows, which have resumed, in the 

 space of a few days, a verdure equal to that of spring. Neither the natural nor 

 the artificial indications of this change of weather were very striking: the most 

 considerable being, probably, the sudden increase of temperature in the nights pre- 

 vious to the more considerable falls of rain. 



Tottenham, Ninth Month, 22, 1818. L. HOWARD. 



Large Meteor. — On the 14th of the ninth month I Sept.) about half-past 10, p. m. 

 a meteor was observed, in a direction nearly due north from Tottenham, which 

 must have been a very conspicuous object to the inhabitants of more northern 

 countries. When first observed, it was but moderately elevated above the horizon 

 on which it appeared to descend slowly, continuing in sight for some minutes. My 

 informant judged its apparent diameter to be at first equal to that of the moon 

 ■when at her greater elevation : it had a diverging train, which was compared to a 

 bru^i : the colour white, changing to red as the body descended and decreased in 

 diameter; at which time a second observer reports that it simply emitted sparks. 

 The course of this meteor was probably directly northward from the eye, which 

 may account for ils apparently slow motion. Further observations from those who 

 may have seen it more to the north will be acceptable. I am not enabled to give 

 the particulars with greater precision than as above.
