:meteorological observations on fujinoyama. 



To Mr. R. Fujisawa, special student in Physics in the University, I am 

 indebted for a caretnlly prepared report of the meteorological observations made 

 by the party visiting the mountain in August ISSO, the work of which has liecn 

 already rcfeiTed to in this volume. From this report I have selected the follow- 

 ing observations and results which will doubtless be of considerable interest to 

 tlio.se who are more or less familiar with the mountain as well as to all who are 

 interested in the meteorology of elevated points. 



The ascent was made by what is known as the Eastern or Subashiri route. 

 A monntiiin IJarometer (mercurial) was carried by the party and observations 

 were made at diti'erent points during the ascent. Upon this route there are ten 

 "stations" or stopping places, the last being at the summit. The following 

 fcvble gives tlie height of several of these st^xtions above the sea, as deduced from 

 the l)arometric observations. It will be reniemliered, of coui-se, that they only 

 pretend to be rough approximations as they are based upon a single observation 

 at each point, the barometric height at the sea level having been assumed to be 

 30 inches. They may, however, prove to be interesting and useful to persons 

 making the ascent of the moimtain in the future. The numbers given represent 

 the vertical height in feet between the various stations at which readings were 

 made.

A numlier of hypsiiuK^tric observations were made during the stay upon the 

 summit. The instnunent used included a Fahrenheit thermometer reading to 

 212. A can'fid t«st of the thermometer in the physical laboratory of the 1 td- 

 vcrsity did not indicate a greater error than one hundredth of a degree at that 

 point. Barometric readings were taki-u at the same time, the results of which 

 arc to lie found in the following table. In the fourth coliuun will also 1k' found
