An erroneous operation in integrating ∫λ3/1-λdλ of Formula 2 of the previous paper (Vol. 26 No. 5, p. 498 of this bulletin) being pointed out by GENSYO, Formula 3, A/κι∞3=|λ+1/2λ2+1/3λ3|λ•5 was now replaced by A/κι∞3=ln1/1-λ-λ-λ2/2-λ3/3.
While the former corresponds to a linear relation, the latter is a relation representable as a curve as shown in Fig. 1.
In this paper it is verified that the theory already presented in Formula 1 of the first paper can be well supported by the data from actual measurements as shown in Figs. 2 & 3.
Hence we have the following relation between the vitamin A contents of fishes, A, and the ratio of the body-length, λ
A=κι∞3[ln1/1-λ-λ-λ2/2-λ3/3]………………………………(3') where ι∞ means the maximum body-length, of the species, λ=ι|ι∞, and κ is a constant.
This paper deals also with the value of κ of several kinds of fishes, calculated from Formula 3 and Fig. 2 and tabulated in Table 1. The values of κ for a definite species (e.g. ABURAGAREI ?? ) are independent of fishing ground, season and depth, those calculated from the formulae and Fig. 3 being presented in Table 2.
