Re: Help with meaning "Urschwinge" for name Archaeopteryx

[David Marjanovic <david.marjanovic@gmx.at>]

Just for the sake of completeness, here are a few nits picked from your 
translations -- none detracts at all from your points:

> Das Thier scheint mit beiden  Füssen gleichzeitig fortgehüpft zu
> seyn, wie es Vögel oft zu thun pflegen, [...] dass diese Fährten

Not "forward", but "away".

> as birds are often in the habit  of doing;

Or "as birds are in the habit of doing often". Part of the confusion is 
caused by the fact that the "zu [...] pflegen" part is completely redundant.

> that these tracks come from  this Urvogel [primordial bird],

There's "just"/"precisely" in there.

"in which case, though, the small fourth toe of its foot would not have 
left (behind) an impression". The passive voice would be _in welchem 
Falle allerdings kein Abdruck der kleinen vierten Zehe seines Fußes 
hinterlassen worden wäre_... or rather _sein würde_ instead of _wäre_, 
given that the original has _haben würde_ instead of _hätte_; that'd 
give us four verb forms in a row.
