    APPENDIX. The Clinical Research Association, Limited, Watergate House, Adelphi, London, W.C. 14th November, 1910. No. 6688/11. To Dr. A. McCausland. The Specimen of Water marked No. 1 from a covered reservoir* received here on 5th November, 1910, has been examined and I have been instructed to forward the following Report thereon :— Results. — Grains per Gallon. — Parts per 100,000. (1.) Chemical— Total Solids (dried at 120° C.) ... 56-77 81-10 Combined Chlorine ... 0-70 9-57 Expressed as NaCl ... Mi> ... 11-05 15-79 Nitrogen as Nitrates ... ... ... 0-01 0 01 Nitrites ••• ... Nil. Nil. Saline Ammonia ••7 t•• 00019 0 0027 Albuminoid Ammonia ... ••• 0-0028 0-0040 Oxygen absorbed in 4 hours at 27° C. 0 016 0-023 Temporary Hardness... 21°-2 Total Hardness , . . . . . 35° *4 Permanent Hardness ... ••• ••• 14°-2 Lead or Copper ... ... Nil. Nil. (2.) Bacteriological— B. Coli ... ... Present in 2 c.c. Strepto-cocci ... ... Present in 10 c.c. B. Enteritidis Sporogenes * Not found in 100 c.c. Conclusions. These results show the water to be decidedly hard and polluted with sewage or animal excreta to a dangerous extent. We have been unable to isolate the Typhoid Bacillus, but the practical difficulties in the detection of this organism in water are so great that a negative result cannot be regarded as any real evidence that it is not in fact present. C. H. Wells, Secretary of the Association. * At this time the water in the reservoir was from source No. 4 only.
