No. 2 was a water free from organic or saline impurities, but of 
so hard a nature, by reason of the carbonate and sulphate of 
lime it contained, as to be an unsuitable water to use. No. 3 
was similarly hard, but was also organically impure. No. 4 came 
from a well bored through gypsum beds ; it contained a very 
large quantity of gypsum in solution. No. 5 was taken from a 
marsh at Dagenham, and is overflow water from the Thames 
below the Crossness sewage outfall. This had an enormous 
quantity of solid residue, and smelt very strongly of sulphuretted 
hydrogen gas. The greater part of the solids consisted of 
common salt. The amounts of ammonia were extremely high. 
Such a water is perfectly unfit for even cattle to drink. Subse- 
quently I heard that several head of stock, feeding on the 
marshes where this water overflowed, had died, in consequence, 
it was believed, of the water, and this I can well understand. 
Potale. — His Grace the Duke of Argyll sent me a sample of 
liquid from a whisky distillery in Argyllshire, which I was in- 
formed was used largely for distributing over grass land in the 
neighbourhood of the distilleries, the liquid being conveyed in 
pipes and run on to the land, the result being very beneficial to 
the grass. The liquid was strongly acid, and its specific gravity 
was l OlG. An analysis of it gave the following results : —
