The "head under wing" or "turn under the path" symbol is the "C"-like mark after the dog on the fourth line; and also the slanted "C" on the seventh and ninth lines (cf. Sullivan, 7). Taking into account the re-interpolations of these symbols, the passage now reads (rearranged units are within square brackets):
