II. Change in the Freezing Point of Thermometers, 



The following observations on this subject, a notice on which ha^ 

 already appeared in the Annals (for July, p. 74), are extracted from 

 Mr. Daniell's newly published Meteorological Essays, p. 368. 



*' With respect to the change in the freezing point, which takes 

 place in time in the best thermometers, I have lately had an unexcep- 

 tionable opportunity of confirming the assertions of the French and 

 Italian philosophers. Mr. Jones has obligingly put into my hands two 

 thermometers of the late Mr. Cavendish, which have evidently been 

 constructed with much care. The mercury in the balls of both flows 

 freel}' into the tubes when reversed ; and when suffered to fall sharply, 

 strikes the ends with a metallic sound. The same click may be heard 

 in the bulbs, when it is permitted to fall back, and the cavity closes 

 ^vithout the slightest speck. These indications of a well-boiled tube 

 are rarely to be met with in the common thermometers of the present 

 day. They are mounted upon common deal sticks, and the gradua- 

 tion, which is only continued for a fe\y degrees about the freezing 

 point, is engraved upon a small slip of brass. The degrees are very
