That the pitch of partial tones emitted from 1/2 Lb salmon cans has a negative correlation to the weight of net content of cans is ascertained. The correlation is, however, not very high owing to the variation of the weight of emptied cans, which is itself negatively correlated with the pitch of tones. The partial correlation c_??_efficients are significant.
