about 1 8 feet above the furface of the ground; and though, in 

 a town, it is impofTible to prevent local caufes from afFecfling the 

 thermometer, yet the current of air is generally fo confiderable 

 as to prevent thefe irregularities from riling to any great a- 

 mount. 



The regifter contains the flate of the thermometer for three 

 different hours of the day, viz. 8 A. M. lo P. M and alfo about 

 2 o'clock, w^hen the thermometer is higheft. The hour of this 

 laft obfervation is not however fixed ; it is fuch as to give near- 

 ly the greateft heat of the day, and varies from i to half paft 

 2, or even 3 o'clock. The abftradl contains the greateft and 

 leaft heights of the thermometer, that have been obferved at any 

 of thefe hours in the courfe of each month : It contains alfo the 

 mean of the morning, mid-day, and evening obfervations ; and 

 likewife the mean of all thefe means, as being nearly the me- 

 dium temperature of the whole month. 



The rain is put down for 1794 and 1795 from a rain-gage 

 kept in Edinburgh, and for 1 796 from one kept in the Botanic 

 Garden with great accuracy, under Dr Rutherford's particu- 

 lar infpedlion. The Botanic Garden is half-a-mile north of 

 Edinburgh, and about 1 00 feet above the level of the fea. 



In the remarks, reference is fometimes made to the Meteoro- 

 logical Journal kept fome years ago at Hawkhill, near Edin- 

 burgh, of which an account is given in the Philofophical "tranf' 

 anions of London 1775, p. 462.
