'Both Vipers (or Adders) and Snakes, the latter in particular,'
'latte ' included a following space, so made the assumption that the word here is 'latter'.
Changed.
'Mergus acutarostris cinereus'
'acutarostris' may be 'acutirostris' as used elsewhere.
Spelled as in original.
'sprdding the finnes into a liuely posture do hang them'
'sprdding' is an odd spelling for spreading.
