and cold, having 0° for freezing and 100° for boiling. 

 As there are 180° Fahrenheit, 80° Reaumur and 100° 

 Centigrade between freezing and boiling, the divisions 

 are therefore as 9° F. to 4° R. and 5° C. 



To change from degrees of F. above the freezing 

 point to the other systems deduct 32, di\'ide the re- 

 mainder by 9 and multiply by 4 or by 5 respectively. 

 To change from C. to F. divide by 5, multiply by 9 and 

 add 32, etc. As the metric system is gradually being 

 introduced ever^^^here instead of the old systems for 

 weights and measures^ so also is the Centigrade ther- 

 mometer being substituted for the others and in cook- 

 ery it may soon be used exclusively.
