IV. On the redetermination of the coefficient of expansion of mer- 

 cury. 



The pure mercury was weighed in a bucket in the water at dif- 

 ferent temperatures. The glass bucket was made from the end of a 

 test-tube (its length being about 20 millims. and width 15 millims.). 

 The expansion of this sort of glass was found to be 



V^Vo (1+0-00002566*).
