 Corrections and results. 



Final results. 



bath a tube is mounted symmetricallj with the thermo-element, and 

 has the same shape and dimensions as the latter. Comp. also Comm. 

 N". 94^ § 1. For the attainment of a constant and uniform tem- 

 perature with this cryostat we refer to Comm. N°. 94«^ and the 

 Comms. quoted there. The temperature was regulated by means of 

 a resistance thermometer. For the two measurements in liquid hydrogen 

 we have made use of the cryostat described in Comm. N°. 94/. 



b. With a bath of liquid methyl chloride we have obtained the 

 temperatures — 30^ — 59° and —88°; with ethylene — 103°, 

 — 140° and —159°; with oxygen —183°, —195°, —205° —213° 

 and —217°; with hydrogen —253° and —259°. 



c. The temperatures are read on the scale of the hydrogen thermo- 

 meter described in Comms. N°. 27 and N". 60. On the measurements 

 with this apparatus at low temperatures another communication will 

 erelong be published.
