netrated the pores of the bronze and preserved it from rust. 

 Naturalists will soon see if this reasoning;, which seems sa- 

 tisfactory to Plutarch and his conteinporarieSj can be ad- 

 mitted at present. 



The time of Alexander was the epoch at which the art of 

 founding flourished most in Greece. Th.e Athenians erected 

 to Demetrius Phalercus, who governed Athens for ten years, 

 36o bronze statues, several of which were equestrian, or 

 accompanied with chariots and horses; and, what appears 

 almost incredible, all these works were commenced and 

 finished in the space of 300 days*. lA-sippus seeins to 

 have exhausted this art, for it fell with him.

XXIX. An Account nf ttvo Children lorn luitli Cataracts in 

 their Eyes, to show that their Sight was ohscured in very 

 different Degrees ; iviih Experiments to determine the pro- 

 portional Knondedge of Objects acquired by them immedi-

JVlu. Cheselden's observations on this subject, recorded 

 in the Phil. Trans, for the year 1728, pointed out two ma- 

 terial facts ; that vision alone gives no idea of the figure of 

 objects, or their distance from the eye, since a very intelli- 

 gent boy, 13 years of age, upon recovering his sight whs 

 unable to distinguish the outline of any thing placed before 

 him, and thought that every object touched his eye. 



Mr. Ware's cases, which have also a place in the Phil. 

 Trans, for 1801, and are compared with that of Mr. CheiL-l- 

 den, appear to lead to a difl'erent conclusion. The follow- 

 ing observations arc laid before the society with a view to ex- 

 plain this circumstance.

 St. (icorge's Hospital, under my care, on the 17th of July
