The author, though born in Scotland, was Professor of Chemistry at the 

 Jardin du Roi, Paris, in 1606, said to be the first in France. In the 

 fourth part of this work he treats of crystallography in a scientific way, 

 being the earliest to do so. French biographers, in accordance with 

 their habit of misspelling proper names, write his name Dawisson, 

 Davisson, and d'Avissone, Guillaume.
