The exposed right testis of the same fish is exhibited in Figure 1 (lower). The author has been unable to find comparable data for adult male salmon, but believes from personal ob- servations that the testes weights of the precociously mature parr are relatively much greater than those of the sexually ripe adults. So, if loss of sex products is the precipitating cause of the sequence of changes ending in death, one would certainly expect these fish to die. Examination of the scales for absorption at the periphery was made in only six of these fish, since similar observation had been made in 30 such parr previously. This was done in an earlier unfinished experiment, described later in the present paper. None of the scales showed absoriD- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
