and the fact that the curve follows this law shows that specimens 
of different lengths are almost precisely similar in form. The 
constant for three different points on the curve was determined, 
giving the figures -0065, -0007 and -0008. Taking -0007, the 
weight will be found in ounces, if the cube of the length in inches 
be multiplied by that number. 
It is known that the relationship between the breadth and the 
length is not that stated for the first few weeks of the fish’s life 
that is to say during the period of transformation, but this period 
is so short compared with the period of growth that it does not 
prevent the line of breadth and the curve of weight converging to 
an origin in 0. 
The present most unsatisfactory condition of our knowledge of 
the growth of this species, makes it impossible for me at present 
to state definitely the relation of time to the facts expressed in the 
chart.
