gallon, in tlie ''Stagnant Pond'^ 2.2-4 grains, and in the 
" Trent Water^^ 20 grains. 
Assuming these numbers to be correct, it will be readily 
conceded that Dr. Truman is not justified in drawing the 
positive conclusion named in the sentence just quoted, for 
many thousands of men and the lower animals drink with 
impunity New River and Thames water daily, both of which 
contain from 17 to 22 grains of solid matter per gallon. 
Subsequently Dr. Truman observes, that "The great 
amount of organic matter in the water obtained from the 
stagnant pond points to that as the cause of disease in this 
case.^’ To this statement I would reply, that, while admit¬ 
ting the presence of organic matter in a water may be justly 
regarded with suspicion as being a possible cause of disease, 
or as supplying a condition favorable to its development, 
there are many waters which contain much larger quantities 
of organic matter than those found by Dr. Truman in the 
stagnant pond, and which have nevertheless never been known 
to produce any ill effects on the horses, cattle, sheep, and 
other animals that drank them. During the drought last 
year, and shortly after examining the Colwick waters for 
Mr. Cave, I analysed the water from a stagnant pond on a 
farm near London. This water contained 28*7 grains of 
mineral, and 18*2 grains of organic matter per gallon, and yet 
it has never been observed to prejudiciall}'^ affect the health 
of any of the many horses, oxen, and cows that drank it 
daily for several months. 
No doubt organic or organised matter is in many instances 
productive of disease, but I believe the activity of such 
substances in this respect is dependent much more upon con¬ 
dition than upon quantity.
