BOTHAMLEY : MINERAL WATERS OF ASKERN IN YORKSHIRE. 351 
any kind, but is securely covered in. The water can be drawn from 
the well by means of an ordinary pump placed just over it, and is 
conveyed to the Pump Room through a pipe embedded in the peat. 
The sample for analysis was of course taken from the pump over 
the well. 
It is obvious that this water, coming directly out of the peat 
and passing through a few feet only of lead pipe that has been in use 
for many years, represents most nearly of all the four the water as it 
actually occurs in the peat. For this reason special attention was 
paid to it in the course of the investigation. 
Analyses. 
The samples of water were collected with all the usual precau- 
tions, and as the methods of analysis adopted differed but little from 
the ordinary routine it is unnecessary to enter into details.* The 
results are given in Table A.
