19 X 8 hours = 6 8 



19 X 48 mill. = 15 12 



19 X 34 sec. = 7 36 



19 X 12 lunations = 6732 23 19 36

George Town, Columbia (U.S.) Feb. 22, 1820. 

 " We are in hopes that our winter is over; in fact, we had last 

 week some as hot weather as 1 ever experienced in England, but 

 the following statement of the height of the thermometer will 

 give you some idea of its actual state : lOth. Very cold wind, 

 with sharp sleety snow. 1 1th and 12th, warmer. ISth, too hot 

 at 4 o'clock P.M. to walk comfortably, even thinly clad. 14th, 

 hotter still. 15th. Thermometer at 3 P.M. 76", at 6, 66°, at 

 11, 62". 16th. Thermometer at 3 P.M. 66°, at 7 P.M. 73°. 

 This day we had no fire in our room, our windows wide open, 

 coat ofl^ &c. &c. The ladies all resumed their summer thin ap- 

 parel. 17. Thermometer at 8 A.M. 62°, at 3 P.M. 66". Ve- 

 getation has come on during these last three days with a rapidity 

 I never before beheld. 18th. Weather much cooler. 19th. 

 Thermometer 2 P.M. 54°. 20th. Cold wind. Thermometer at 

 3 P.M. 49". 21st. Colder still, with a N.W. wind. Thermo- 

 meter 44" at 3 P.M. We expect it colder still to-morrow, and 

 then probably we shall have it as hot again as it was last week."
