Obviously it's a mistake, but I'm not sure about what. It could be a fragment of some sentence where a space is missing ( " . . . by hand is . . . " ), or a word where there is a space left over but a virgulilla is missing as "amañose" (pronominal inflection of rigging), or perhaps it is an editing error for verbs / manosea where the last /a/ was separated and at the beginning .
