come aware of the value of accurate details in publications rela- 
ting to this, his favorite science, he must often have failed to 
record facts, the importance of which none but those learned in 
this branch of knowledge are prepared to appreciate. 
The work of making the plans and drawing the sculptures ad 
bas-reliefs, was committed to Mons. Flandin, a French artist, 
This gentleman, besides being master of his profession, brought 
to this field extensive experience, acquired in similar labors 
among the ruins of Persepolis. His aim in performing the part

elevation of the walls, and the present state of all the bas-reliefs 
and sculptures, leaving injured portions and imperfections in the 
ruins to appear in the drawings, and to be restored and improved

visiting the ruins, while several hundred miles distant from them, 
and at intervals of time crowded with other important duties, is 
his apology for this remark.
