Column I., which is only corrected for temperature, is 
almost the sameas V., and the figures in column II. are greater 
than V. 
I shall add to these observations of my own three observa- 
tions of the same height made by the Rev. Professor Jellett in 
the neighbourhood of Zermatt. I have calculated the two fol- 
lowing Tables from the figures furnished by his note-book :— 
The lower station is at Zermatt, the upper at the Schwarz- 
see: —

very striking; it is also remarkable that No. 3 of column | be
