PROCEEDINGS OF THE PHILADELPHIA ACADEMY OF NATURAL 
Sciences, Nov. 8.—Dr. Sharp called attention to the presence d 
retinal cells upon the siphon of Solenensis. His attention was fist 
drawn to the matter by observing that these mollusks retracted

pours its icebergs into the ocean, The region is singularly favor 
able to vegetation, and the forests, though of few species, a 
often so dense as to make travel impossible. The trunks fè 
quently touch, in which case their timber is of little value.
