1875, and the second (b) on the 20th of the same month 
1876. The following data were obtained on analysis. 
Sample (a) had an almost imperceptible Alkaline reaction. 
(1) Specific Gravity — Bottle holds 25'031 grams Water. 
„ „ 5, 25-176 „ Mineral Water. 
Specific Gravity — T00579 at 15° C. 
(2) Ammonia — Half a litre distilled by Wanklyn’s process gave : 
0-47 grams free Ammonia and -03 of Alluminoid 
Ammonia, equal to 0-94 and 0-06 pts. per million 
respectively. 
(3) Chlorine — 10 c.c. of the water required 33* 1 c.c. Standard 
Nitrate of Silver (1 c.c.^rl m. grm. Cl). 
(4) Total Solid Matter — 100 c.c. on evaporation gave 0-729 
grm. which on analysis gave — 
(5) Silica — 0-0006 grm. 
(6) BaS04 — 0-294 containing 0*1008 SO3. 
(7) CaCOs— 0-1088 „ 0*0608 CaO. 
(8) MgaPsO;— 0-08 „ 0.0288 MgO. 
(9) Traces of Iron and Alumina were found. 
Sample (6) had a neutral reaction. 
(1) Total Solid Matter — As a mean of three determinations 100 
c.c. gave 0-7352 grams. 
(2) Chlorine — As a mean of two determinations 5 c.c. took 
16*65 c.c. Stand. Ag. NO3. 
(3) Hardness— 10 c.c. were made up to 250 c.c. and 70 c.c. 
gave 4*1° of Hardness. 
(4) Iron and Alumina — Traces were found.
