—6126~— Dr. Leavenworth on several New Plants. 
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 and 
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 ~ 
assigned him, has been to represent with distinctness and accu- 
racy, the size and character of the mound, the ground plan and 
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 
or not, as may suit the taste and imagination of those who may 
examine his records. 
We understand that it is proposed to publish the inscriptions 
and drawings in four folio volumes, each volume to contain about 
a hundred plates—half being inscriptions and half plans and 
draughts. It is sufficient assurance of the character of this forth- 
coming work, to say that it is in the hands of the French govern- 
ment, and that it will be performed in the best style of the best 
artists of France. 
In conclusion, the writer would beg not to be considered ac- 
countable for any thing more than the general accuracy of the 
foregoing statements. The fact that he writes six months after 
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.
