This table is founded on the su^Dposition that up to 100° of Fahrenheit's 

 Thermometer ; log expansion for 7i° = n x log expansion for 1° ; which is 

 true sufficiently. The linear expansions of Gold and Silver have been taken 

 from Vol. I of Professor Miller's Chemistry ; the others from the paper 

 in the ' Philosoj)hical Transactions' on Standard Weights. 



The argument of tliis Table is to be T — 32° ; or T itself can be 

 taken if the number at the head of the column be applied. 



Thus for brass at 85-35° we have 



Br 50° 000622-30 or Br 80° 000995-68
