In 1876 the hardness varied from 22° to 2ii°, and on 7th Dec., 1876, 



it was 25^°. 



I do not find that there is any regular difference between the hardness in 

 summer and winter. Differences can be traced to heavy rainfall and the 

 rate of pumping : e. g. the hardness of Bootle-well water was taken weekly for 

 a year ; it was generally about 23°, but after heavy rains it fell to 22° and 

 21 0, 8, and in very dry weather it rose to 24°. On 1st October, 1875, the hard- 

 ness was 23°, and on 6th October, when the level of the water was 12 feet 

 6 inches above the bottom of the well, the pump was stopped for repairs. On 

 the 8th October the water rose to 34 feet, and there was no unusual variation 

 in the hardness ; at that time heavy rains began to fall, and on 15th Octo- 

 ber, the level of the water being 48 feet, its hardness fell to 18°. The 

 hardness due to magnesium salts was almost the same at this time as before 

 the change, the difference being due to calcium salts. Pumping was then 

 resumed on 15th October after the sample was taken, and in 7 days, viz. on 

 22nd October, the level was reduced to 17 feet and the hardness rose again 

 to 23°. 



On 31st January, 1877, the water of well was 24-56

In 1875 the percolating water from the upper strata at 40 feet above the 

 bottom of the well was 10°, while the mixed water of the well taken at the 

 same time was from 16° to 16^°. 



On 5th Sept., 1876, the water of the deep bore was

In 1876 the average was from 18° to 19|°.
