1896.] Mr Griffiths, On Thermometric "Fixed Points." 233 



accurate scientific thermometry it would only mean an alteration 

 in the table of corrections for each instrument, and in translating 

 old results it would simply mean multiplying by a factor 

 1 ±0038 " 



I may say that I am in general in hearty accord with the 

 propositions advanced by Professor Hicks although, at the same 

 time, we differ on one or two minor points. 



The conclusions I have arrived at may be summed up as 

 follows : — Our present definition of the freezing point is theoreti- 

 cally sound but practically impossible ; our present definition of 

 standard boiling point is practically satisfactory while theoretically 

 capable of improvement.
