" Bhs I'instant que je me suis consacrfi a la medicine, persuade que la connoissance des corps 

 naturels, source vinique de la mati^re medicalej est indispensable au m^decin, qui en tire tous ses secours,

 homines ; je n'ai cesse d'y employer les momens, dont les occupations norabreuses attach^es a notre ^tat, 

 m'ont laiss^ la disposition."
