his favorite study, seen in this botanist of almost eiglity 

 years. To-day he had met with a species, which lie exhib- 

 ited, the like of which he had not found for many years. 



F. W. Putnam, of Salem, proceeded to describe must of 

 the zoological specimens taken during the day. He also, 

 by the help of the blackboard, explained the four divisions, 

 or branches, of the animal kingdom ; sliowii)g how the radia- 

 ted structure characterizes the Star-fishes, Jellj^-fishes, and 

 Polyps, or coral animals, hence called Radiates ; how the 

 character of concentration is stamped on all animals belong- 

 ing to the branch of Mollusca, of which the Clam, Snail, 

 and Squid are common examples ; whereas, in the branch 

 to which the Insects, Crabs and Worms belong, articulation, 

 or a division of the body into segments, added to an equal 

 arrangement of parts on each side of the longitudinal axis, 

 and a tendency to an outward display, are the principal 

 characteristics ; this branch is called Articulata ; while in the 

 fourth branch, that of Yertebrata ; formed of the Pishes, Rep- 

 tiles, Birds and Mammals, including Man ; the body is divided 

 by a longitudinal axis, the back-bone, into an upper and lower 

 arch; the upper containing the biain and spinal chord, 

 wliile in the lower are situated the organs of vegetative life. 



In reply to questions, Mr. P. said what we call the locust 

 is quite another insect. The oriental Locust is only a spe- 

 cies of what we call a Grasshopper ; while our Locust ought, 

 instead, to be called the Harvest Fly. Again, the real 

 Grasshoppers are small green insects, quite different from 

 those that have borrowed this name. The noise produced 

 by these creatures is not at all vocal, but made by a brisk, 

 fiddling movement of the rough hind leg aci'oss a part of the 

 wing-cover. Further, Mr. P. stated, that the whales now on 

 exhibition at the Aquarial Garden, Boston, were genuine 

 specimens of a small species known to naturalists as the 

 Beluga ; and were very well worth an examination.
