§ 3. Results. 



In order to be able to make conclusions fi-om table I we 'remark 

 that the later determinations have been made with the same thermo- 

 meter filled with distilled hydrogen '). 



From llie results of table I and some earlier determinations at the 

 same temperatures made with the resistance thermometer before it 

 was broken, we may derive. 



1. A comparison Detween the indication of the resistance thermo- 

 meter before and after the l)reaking of the wire, abstracting from the 

 reading errors of (he hydrogen and the resistance thermometer, by means 

 of the determinations of March 25, June 29, and July 3. They give only 

 small differences for the observations oji the last two dates. Indeed 

 if we compare the dilFerejices O — C^i/ of table II of Comm. N". 95' 



1) With the earlier determinations this was tlie case for only some among them. 

 We may derive from former measurements (comp. Comm. 95e), that this will give 

 no ililference till — 217°, l)ut for measurcmenls in liydrogen this has not been proved 

 experimentally. Tiio method of filling by means of electrolytic hydrogen, provided 

 it be done carefully, may be considered as perfectly satisfactory also for these 

 temperatures. As tins method, however, involves a more complicate system of 

 auxiliary apparatus the other must be preferred with regard to the reliability.
