XIX. Of some Thermometrical Observations, made by Sir Robert Barker, 

 F. R. S., at Allahabad in the East Indies, in Lat. 25° 30' N. during the Year 

 1767, and also during a Fbyage from Madras to England, in 1774. From 

 the original Journal by the Hon. Henry Cavendish, F. R. S. p. 202. 



The greatest part of the observations at Allahabad were made within doors; 

 several were made within a tent placed under the shade of trees, some in the 

 open air in the sun, and some in the open air in the shade; but there is no re- 

 gular series of observations in any one place; nor were they made at stated times 

 of the day. Though a thermometer kept within doors is but a very indifferent 

 measure of the heat of any climate; yet as I have not seen any thermometrical 

 observations made in that country, except a (aw during the heiats of the summer, 

 and printed in the Philos. Trans., vol. Ivii, p. 218, I have set down the greatest 

 and least heights met with in each month.
