COMPARISON OF THE THERMOMETRICAL SCALES. 



The first three tables of this set give a simultaneous comparison of the three scales 

 mostly used at present in Meteorology, and especially of the portion of the scales not 

 comprised in the more extensive tables which follow them. They form thus a com- 

 plement to these last tables ; but as most of the temperatures contained in them do 

 not occur in Meteorology, the comparison of the full degrees was found sufficient. 



These three tables have been taken from E. L. SchubartJi's Collectidn of Physical 

 Tables. Berlin, 1836. 



Tables IV. to IX. being more useful to the Meteorologist, the calculation has been 

 carried out for every tenth of a degree. Tables VII. and IX. are from the Annuaire 

 Meteor ologique de France ; the others have been calculated. 



A comparison of the Centigrade and Fahrenheit degrees near the boiling point, for 

 every tenth of a degree, for the sake of the comparison of standard thermometers, 

 will be found at the end of Table VI. 



Tables X. to XV. will be found useful^ for comparing differential results, such as 

 ranges of temperature, and any relative amount expressed in degrees of different 

 scales, without reference to their respective zeros.
