the Water of the Mere of Diss. 
E. The undissolved portion now weighed 25 grains, and was 
digested with diluted muriatic acid : a great part was dissolved, 
with much effervescence, and, being filtrated, afforded, by am- 
moniac, of alumine 1.50 gr. From this, I afterwards sepa- 
rated a very minute quantity of iron, by means of prussiate of 
potash. 
F. Carbonate of soda was then added to the liquor, and 
precipitated carbonate of lime 21 grains. 
G. The insoluble residuum weighed 3.50 gr. ; and proved 
to be principally carbon, (produced by decomposed vegetable 
matter, ) with a very small quantity of siliceous earth. 
The result of this analysis was, therefore, 
B. Muriate of lime - - - 18 
C. Muriate of soda, with a very small portion of 
sulphate of soda - - - 10 
D. Selenite - - _ - 1 70 
E. Alumine, with a portion of iron too small to 
be estimated - - - ' ; - 1 £0: 
F. Carbonate of lime - » - 21 
G. Carbon, with a little siliceous earth - 3 50

It is worthy of notice, that the iron present was in so very 
small a quantity as not to be detected by any test, till it had 
been separated in conjunction with the alumine. 
The water No. 5, from Mr. Wiseman's account, does not 
appear to have been concerned in producing the effects which 
he has observed, and the quantity was too small to be sub- 
jected to a regular analysis, I noted, however, what follows.
