Dr. Chas. Pickering observed, witli reference to the 

 sense of smell in fishes, that he had examined the brain 

 of the shark, and that in this, as well as in cartilaginous 

 fishes generally, the development of the olfactory nerve 

 and the olfactory lobe of the brain was very considerable. 



The chairman, Dr. D. H. Storer, called attention to 

 the last volume of the work on the Terrestrial Mollusca 

 of the United States, by the late Dr. Binney, edited by 

 Dr. A. A. Gould, a copy of which had been recently pre- 

 sented to the Society. He stated that Dr. Binney was 

 desirous, and left directions for the completion of the 

 work, the charge of which was committed to Dr. Gould. 

 It had taken ten years to complete it; but the duty had 

 been nobly and admirably performed, and it was exceed- 

 ingly gratifying to him to say that it would prove most 

 creditable to the Society and to the country. 



Mr. Amos Binney said that ten years might seem a 

 long period for the completion of the work, but any 

 apparent delay was more than sufficiently accounted 

 for by the time occupied in collecting the materials, 

 which, at the decease of his father, were very widely 

 scattered. 



Dr. A. A. Hayes exhibited some fragments of iron and 

 bronze vessels from the volcanic ashes of Pompeii, which 

 had repassed from the state of a wrought metal to that 

 of the original ore. 



Dr. J. B. S. Jackson exhibited an Intestinal Worm, 

 (Ascaris lumbrico'ides,) which was passed from the rectum 

 of a child, with about an inch of its body inserted through 

 the eye of a common dress-hook. He observed that this 

 example illustrated the singular tendency of this worm 

 to crawl through perforations in the intestine, into the 

 duct of the gall-bladder, or into the appendix coeci.
