dimensions and weights obtained by dividing the totals for each group of follicles by the 

 number of follicles. They show considerable differences in the averages of the follicles 

 obtained in different years from the same district. The differences in the follicles of 

 each year are still more considerable, and this may be illustrated by stating the dimen- 

 sions and weights of the largest and smallest follicles, and of their constituent parts, among 

 those examined from the supplies obtained in each of the three years : —

From the data given in Table III., it appears that the average length of the 337 

 scraped follicles there represented is 10*8 inches, and the average weight 178*6 grains. In 

 order to obtain some indication of the dimensions and weights of the constituent parts 

 of average follicles, twenty follicles, whose size and weight were about the average, were 

 selected from the supply of 1885, and an analysis, similar to that shown in Table III., 

 was made of their constituent parts. The twenty selected follicles varied in length from 

 9*5 to 1T5 inches, and in weight from 172'25 to 198 grains. The results are stated 

 below in averages.

On comparing the figures in this Table with those in Table III., the most noteworthy 

 difference between them is seen to be that in the twenty follicles selected as average-sized
