XIX. An Account of fome l^henjtometrical ObfervationSy 
made by Sir Robert Barker, F. R. S. at Allahabad in 
the Eaft Indies, in Lat. 25° 30' N. during the Tear 
1767, and alfo during a Voyage from Madras to Eng- 
land, in the Tear 1774. Extracted frojH the original 
Journal by the Hon, Henry Cavendifh, F. R, S, 
Redde, April 6 ,v | "^HE greateft part of the obfervations 
at Allahabad were made within doors ; 
feveral were made within a tent placed under the fliade 
of trees, fome in the open air in the Sun, and fome in 
the open air in the fhade ; but there is no regular feries 
of obfervations in any one place ; nor were they made 
at Rated times of the day. Though a thermometer 
kept within doors is but a very indifferent meafure of the 
heat of any climate ; yet as I have not feen any thermo- 
metrical obfervations made in that country, except a few 
during the heats of the fummer, and printed in the 
Philofophical TranfacRions, vol. LVII. page 218 . 1 have 
fet down the great and leaft heights I meet with in each 
month.
