tremely diseased, and further I have only once known it to fail 
in doing so. And again if the commonly accepted belief is the 
right one, why is it that slight cases do not respond to a small 
dose, but require from four to six times a larger dose to get the 
reaction ? I think the amount of reaction obtained depends on 
an entirely different condition. 
It has been with me a subject of frequent notice that the 
highest reactions have been obtained from fat and plethoric 
animals, some of them badly diseased, others but slightly. Then 
again the cases in which the lowest reactions have been noticed 
have been noticed have been in creatures thin and emaciated, 
and whose vital energy has been at the lowest ebb, some of them 
slightly diseased, others extremely bad. Testing the latter 
varieties I can only compare them to a man attempting to light a 
stove having but little fuel in it, and the chimney stuffed with 
soot. There is not enough fat on the creatures to make a 
decent fire of, nor sufficient vital energy to cause draught 
enough to burn up what is there. In such cases a heavy dose 
will only snuff the candle out and leave us still in the dark. 
Since January, 1894, I have tested in all twenty-three herds 
of cattle comprising a total of 415 heads. Here are the tests 
and results in tabulated form :
