weighed within thirty minutes after the administration of chloro- 

 form. In each animal thyroids, adrenals, and hypophysis were 

 preserved in Bouin's fluid or formol-Zenker's solution for subse- 

 quent histological study. 



In bone measurement the two legs of each animal were stripped 

 of muscle and boiled in a weak alkali solution for a short time, 

 after which they were cleaned of all muscle and ligaments. They 

 were then measured by means of graduated calipers (grad. to .01 

 cm.) and the length of the two corresponding bones averaged. 

 Second measurements were made at a later date by Mr. N. F. 

 Fisher, who was unacquainted with my measurements, and the two 

 sets compared; in case of differences a third measurement was 

 taken. 



III. GROWTH CURVES. 



The weights of each animal of the experiment on each thirty 

 days is given in Table I., and the growth curves for the four 

 groups are shown in Fig. I. These curves were constructed from 

 an average of the weights of all animals in each of the four groups 

 for each weighing period i.e., 30, 60, 90 days, etc.
