The curve to the left is the "abnormal curve" and marks the inception of symptoms such as loss of balance. The obvious fall in toxicity below 420 cu. mm. per liter is shown by the stippled death curve turning off to the right. Class i was of fish 2-9 grams in weight; class 2 was of fish 10-19 grams in weight; class 3 of fish 20-25 grams in weight. The significance and curve directions are discussed in

It is very likely there would have been much intercrossing if many experiments had been run and ten or more classes had been separated. It may be that difference of physiological condition of different batches of fish (as chance allots in the purchase of fish for standardizing) may give results with the same concentration of the same drug as far apart as the different weights of fish here have done. In the case of the fish used here all were caught in the same place, and kept in constant environment in the same tank until used. The upper and lower boundaries of the curve at the lower right hand edge of the cart were determined by experiments not shown in the graph.
