the end of the trdrd year came so far outside the range of the curve that they were 

 excluded entirely, as were also one first-year length and two third-year lengths of 

 females, for the same reason. The curves obtained for the males were considerably 

 smoother than those for the females, but fairly satisfactory results for the first three 

 years were obtained for both sexes. The graph obtained thus for males at the end of

their third year closely resembles that for three-year-old males, the hump being for 

 a little smaller size, as the three-year-old individuals had already grown somewhat in 

 the early part of their fourth year. The same remark applies to the graph for the 

 females. The mean for each age and sex was calculated, and is indicated in the figures 

 (figs. 5 and 6). If these be compared with fig. 3 it will be observed that the mean 

 of the male curve is about 1-5 cm. larger and that of the female curve about 3 cm. 

 larger in the latter, owing to the growth in the part of the fourth year which had 

 elapsed before capture.
