 Imperial destroyer of Rheims Cathedral.

 pressure to the action of the ' setherial particles darted from the celestial bodies '. These particles have also to do duty in 

 explaining vegetation, smell, and the subjects mentioned in the title. There is also a description of a curious contrivance 

 to ascertain the longitude. Leeway appears to have been quite unknown to the learned author.
