much can be remarked about the barometrical readings, except that when a 

 number of readings were taken at one place, owing to a longer stay than usual 

 being made at that place, considerable fluctuations were noticeable. Thus at 

 Ch'ing-yang Fu, on February 17th, the barometer stood at 26*13 inches. 

 On February 19th, it stood at 26*55, giving a difference of forty-two points. 

 Again at Ku-yiian Chou, the barometer varied from 24*05 on March 9th to 

 24*47 c>n the i6th, also a difference of forty-two points. No atmospheric 

 disturbance, or changes followed these fluctuations. 



Wind was recorded every day. During most of the time it was but a 

 light wind, but on nineteen occasions it freshened up, being recorded as 

 moderate, whilst on eight occasions it was noted as strong. 



On sixteen days the wind blew from a north-westerly direction. It was 

 from this direction that it generally blew when it was of more than usual 

 strength. On nine days it blew from the north, and it freshened up usually 

 when in this quarter. When the wind was in the south-west or west, as it was 

 on eight and seven days respectively, it was never very strong, whilst a 

 southerly wind was generally fresh. The prevailing wind during this time 

 of the year may be considered to have been from a general northerly direction, 

 though it frequently shifted to other points of the compass. 



An analysis of the weather notes leads roughly to the following deduc- 

 tion : — North winds usually meant fine weather with cloudless skies, while 

 north-westerly winds brought decidedly more clouds. West wind brought 

 snow or rain, and was invariably cloudy. South-west winds brought snow, 

 clouds, or fog, while south winds again invariably brought up clouds. Any 

 thing might be expected if the wind was in the south-east, east, or north-east, 

 but it was so seldom in these quarters that no certain deductions could be 

 drawn. 



Clouds were recorded very frequently during these months of travel, 

 every variety being noticed. Cumulus clouds predominated, being recorded 

 thirty-two times, and were brought up from the north-west, and south-west 

 most frequently. Cirrus clouds were also very frequently recorded, being 

 brought up by north-westerly or southerly winds. Cumulus and cirrus were 

 almost always noted when the wind was variable. Stratus clouds occurred on 

 sixteen occasions, most frequently when the wind was from some westerly 

 quarter, whilst nimbus clouds were noted seven times from all directions. 



Hygrometer readings were commenced on February 14th, as soon as the 

 temperature was high enough, and were kept up with increasing regularity. 

 Usually no very great difference between the two bulbs was recorded, but on
