These 2 lists conjoined making 141 leaves 106 [+] 35 [=] 141 leaves very carefully observed

Therefore we have 9 out of 141 with numerous tentacles give list inflected; & 14 with from 19 to 7 in [illeg] (averaging 9 tentacles inflected) & 32 with from 6 to 1 inflected — so that 55 out of the 141 had none inflected
