 VOLUME OF CASES. 



Values of 1 + .00367 t. 



The quantity i + .00367 / gives for a gas the volume at <° when the pressure is kept 

 constant, or the pressure at i° when the volume is kept constant, in terms of the 

 volume or the pressure at 0°. 



(a) This part of the table gives the values of i + .00367 i for values of t between 0° 

 and 10^ C. by tenths of a degree. 



(b) This part gives the values of i + .00367 1 for values of i between — 90° and + 1990° 



C. by 10° steps. 

 These two parts serve to give any intermediate value to one tenth of a degree by a sim- 

 ple computation as follows : — In the (i>) table find the number corresponding to 

 the nearest lower temperature, and to this number add the decimal part of the 

 number in the {a) table which corresponds to the difference between the nearest 

 temperature in the {6) table and the actual temperature. For example, let the 

 temperature be 682°.2 : 



We have for 680 in table (.6) the number .... 3-4956o 



And for 2.2 in table i,a) the decimal .00807 



Hence the number for 682.2 is 3.503&7 



(C) This part gives the logarithms of i + .00367 i" for values of / between — 49° and 



+ 399° C. by degrees. 

 (d) This part gives the logarithms of i + .00367 i for values of ;■ between 400° and 1990° 

 C. by 10° steps.
