TEXT FIGURES 



Fig. 1. Chart, showing grovsd;h curves for dogs fed on fresh and autoclaved 

 milk. Curves 1 and 2 are for the fresh-milk-fed dogs, and curves 

 3, 4, and 5 are for the autoclaved-milk-fed dogs. Days are 

 given as abscissae and body weights in grams as ordinates. The 

 chart is for the forty-seven days of the experiment only. 

 2. Chart, showing growth curves for pigs fed on fresh and autoclaved 

 milk. Curves 1, 3, and 5 are for the fresh-milk-fed pigs and 

 curves 2, 4, and 6 are for the autoclaved-milk-fed pigs. Days 

 of the experiment are given as abscissae and body weights in 

 kilograms as ordinates.
