March and fell to the 29th, when it commenced to 
rise. The Bourne flow increased from 534°8 cube 
feet per minute on the 27th to 549:1 cube feet per 
minute on the 29th, and it fell to 502°2 cube feet 
per minute on the 30th March. 
‘64th. The barometer fell from the 3lst March to the 
1st April. The Bourne flow increased from 502°2 
cube feet per minute on the 30th March to 525°5 
cube feet per minute on the 1st April, and with 
the rise of the barometer on the Ist April it fell, so 
that on the 3rd April the flow was but 456-7 cube 
feet per minute. 
“Sth. The barometer commenced to fall on the 4th 
April and fell to the 5th. On the 6th it com- 
menced to rise and remained moderately high 
until the 10th April. The Bourne flow rose from 
456°7 cube feet per minute on the 3rd April to 
479°3 cube feet per minute on the 5th April, and 
fell to 399°8 cube feet per minute on the 10th 
instant. 
“It should be observed that after the 24th March 
there was a decline in the Bourne flow, which had 
reached its highest discharge on that day.” 
The Author also gave further information with 
reference to the rise and fal] of the water in deep 
wells, showing that whenever there was a fall in the 
barometer there was a corresponding rise in the water 
line of the well and vice versa; with a rise of the 
barometer there was a decline in the level of the water 
in the well, and this was shown in a most marked 
manner by experiments which were carried out at the 
boring made for the Croydon Rural District’ Council at 
their sewage works at Merton. These results have
