The fixed parts were of cast iron, and were kept at the 

 freezing temperature : the object glass of the micrometer 

 was fixed exactly over the ends of the expanding bars, mov- 

 ing with them, and showing a difference of ^^ of an 

 inch. When the adjustment was perfect, the expansion 

 was found not to vary in dilferent parts of the scale.

Measured the proportions of expansion by asocrtaining 

 the quiescent point of a compound bar. Finds a tardiness 

 in most metals to return to their original dimensions after 

 having been heated, when slowly cooled. Attributes an 

 irregularity to the expansion of glass, which later obser- 

 vations have not confirmed. 



Deluc observes, that all fluids begin to expand more ra- 

 pidly as they approach their boiling points. Rech. sur I'atm.
