Dr BARNES'S Remarks on a Meteorological Journal. 419 



These meteorological journals were commenced on the 1st of 

 January 1801, and regularly continued up to the end of December 

 1824. Observations were made of the thermometer, barometer, 

 quantity of rain, direction and force of the wind, clouds, and the 

 appearance of the sky. These are followed with general remarks 

 on the state of the weather, the occurrence of thunder, of me- 

 teors, and of the aurora borealis. In some places there are added 

 the appearance of the country, the height of the neighbouring 

 rivers, the progress of vegetation, and the migration of birds. 

 The state of the barometer and thermometer, and some other 

 phenomena, were regularly observed and entered in the journal 

 three times a-day, with a mechanical exactness. Mr PITT was 

 seldom absent from home ; and whenever any unavoidable cir- 

 cumstance obliged him to go to a distance, he always appointed 

 a confidential person to take the observations for him. 



At the end of each month, the observations are summed up, 

 the means of each of the three daily observations of the thermo- 

 meter and barometer are given ; the quantity of rain stated ; the 

 number of west and east winds ; the number of wet days ; the 

 highest and lowest degrees of temperature ; the mean tempera- 

 ture of all the observations ; the highest and lowest state of the 

 barometer ; and the mean height of the barometer of all the 

 daily observations are mentioned. 



At the end of each year, the yearly results are stated. We 

 have the annual average height of the thermometer, the annual 

 average height of the barometer, the annual quantity of rain, and 

 the number of westerly and easterly winds. 



The register contains a daily account of the direction and 

 force of the wind. In the monthly and annual summaries, the 

 winds are arranged into two classes, which are called East and 

 West winds. Mr PITT began with the W. and went round by 

 the S. to the E., and all the winds between these two points he 

 classed with the west winds. He then reckoned from E. to W., 

 and classed the NE. N. and NW. and all the winds from the in-
