Stones are sometimes divided by drawing lines on them 

 with fat or oil, and then exposing them to heat. It 

 may be doubted whether the oil, by preventing the eva- 

 poration of moisture, allows the stone to be more 

 heated at the part oiled, and by the irregularity of the 

 expansion produces a separation ; or on the contrary, the 

 oil, having insinuated itself, is converted into vapour at a 

 high temperature, and forces the stone asunder.
