Heat appears to give a partial increase of tenacity to a 

 razor's edge. Probably because the edge cools fastest, con- 

 tracts, and is stretched. 



Dalton on the expansion of gases. Manch. 

 M. V. Nich. 8. III. 130. Gilb. XII. 310. 



Assuming that the absolute heat is as the distance of the 

 particles, Dalton fixes the natural zero at 1547", F. below 

 the freezing point; this Gilbert corrects to H'js", or 

 — 1 566°, F. 



Dalton on the expansion of water by cold.

Ualion says, that in a water thermometer of earthenware, 

 the apparent maximum of density is at 36° or 38°, in 

 queen's ware 40°, in glass 41.5", in iron 42.5°, in copper 

 45.5°, in brass 46°, in lead 49.5°. Nich. 1805. Hence, 

 if we compare the expansion of glass with that of iron, 

 copper, brass, and lead, we shall find, according to Dal- 

 ton's own principles, the maximum at 39.5°, 38°, 38°, and 

 38.5° respectively. The thermometers of earthenware 

 were evidently incapable of great accuracy. The com- 

 parison of iron and lead gives about 37.5°.
