Note. — There is an unaccountable quantity at Timperley. This requires 

 explanation. The wind was from the west, and violent. Did it receive its im- 

 pjirity from an upper current ? 



The quantity of acid was determined by comparing prepared solutions. I 

 doubt if it is very accurate with baryta, and do not intend to use it again.
