310 Correction of the Thermometer. — Comet of 1823-24. 



It is evident that the following formula will nearly represent 

 the numbers of this table, 



F=x. 0-997039-0°-538 

 at least, that the differences are within the limits of the uncer- 

 tainty of the observations. I have therefore not hesitated to 

 simplify the calculations of refractions by making use of this 

 formula."
