The .81 MEV peak of 6028 was not observed
The samples were collected in November 1954
and any C098 present at that time would have decayed to an unde-
tectable level by the time of analysis.
The .67 and 1.12 MEV 7
peaks observed in the whole
samples were absent in
the

on the cobalt separations, thus indirectly confirming the pres-
ence of mn0d and Cst37 in the bonito muscle samples (Fig. 8).
