386 The hot springs of Pai m the Tavoy district. {No. 4, 
bank of the Pai river ; the water here was very shallow, without steam 
or bubbles. It contained much conferve ; and you will see that the 
stones from it are coated with a saline crust. 
Memorandwm.— By A. TwrEn, Esq. 
T have examined the water from the spring near Pai. The sub- 
stances present are Iron, Alumina, Lime, Potash, Soda, Silica, Hydro- 
chlorie Acid, Sulphuric Acid, Hydro-sulphuric Acid and Organic matter 
which is nitrogenous. 
Of the 4 bottles sent, 2 were empty, one but half full, through being 
imperfectly corked, and the fourth held, besides water, a considerable 
quantity of stones and water plants. i 
The siliceous deposit contains in addition to Silica, Iron, Alumina, 
Lime, Potash, Soda, a trace of Magnesia, Carbonic Acid, Sulphuric Acid, 
Hydrochloric Acid and Organic Matter. There is about 12 to 14 per 
cent. of soluble matter, of which the greater part is Carbonate of lime. 
The Soda water bottle which held water from the second. spring had 
nothing in it but stones and conferve. This had a fetid smell, was 
alkaline to test paper, and evolved Ammonia on being treated with 
Hydrate of lime. 
Some of the stones which accompanied the Soda water bottle are 
coated with deposit from the spring, but not in any quantity: this 
is calcareous.
