192 NATTTKAX HISTORY SOCIETY OF DUBLIN. 



whom specimens were given, decided that it was Gulnaria lacustris, 

 quite overlooking that that species of Limneea had the outer lip of the 

 shell revolute, and not as in Amphipeplea even and entire to allow the 

 free passage of its large mantle, which covers the shell, while Gulnaria 

 is destitute of mantle. It is much to be regretted that the animals in 

 the living state of that fine species of Akera, collected by the late Dr. 

 Farran, were not examined ; for the characteristics of the animal, and 

 its large mantle, might have given some clue to its affinities. 



These several points show how necessary is the knowledge of ana- 

 tomy and physiology to clear the doubts of our investigators. Such 

 knowledge my successor eminently possesses ; besides,'his experience in 

 analytical chemistry, geological and mineralogical science, and especially 

 the exact sciences, will ever afford to us invaluable aid, and to such a 

 successor I am proud to yield the chair. 



I cannot conclude without expressing, in the strongest terms that I 

 can possibly convey, my gratitude and warmest thanks for the kind and 

 cordial support invariably given me by the members and officers of 

 the Society during the six years that I had the honour of being Pre- 

 sident, and for the seventeen years previously that I was one of your 

 Secretaries. 



Mr. Andrews then vacated the chair, which was thereupon assumed 

 by the newly-elected President, 



The Rev. Samuel Haughton, M. D., F. T. C. D., F. R. S., &c, 



"Who said that he could not occupy the meeting by making a long 

 speech, nor would he indulge in platitudes, but simply give expression 

 to his very sincere thanks for the honour just done bim by the Society in 

 placing him in the chair for the ensuing Session. He would at the same 

 time, however, without pretence or mock modesty, take the opportunity 

 to express his sense of the disadvantage under which he felt himself to 

 labour in succeeding so experienced a naturalist as the late President, 

 Mr. Andrews. Although he (the President) could not venture to com- 

 pete with that gentleman in his wide acquaintance with the various 

 departments of zoology and botany (which were peculiarly the subjects 

 which this Society was established to cultivate), and who was justly re- 

 garded as the highest authority on the practically important subject, 

 the Fisheries, yet would he venture to say that he would himself yield 

 to none in the amount of interest he felt in the progress and advance- 

 ment of those sciences ; and his efforts should be, that the welfare of the 

 Natural History Society of Dublin should not suffer in his hands. 



Mr. R. P. Williams proposed a vote of thanks to tbe ex- President, 

 Mr. Andrews, not only for his courteous conduct at all times in the 

 chair, and the interest evinced and attention bestowed on the welfare 

 of the Society during the six years he acted as President, but also for 

 his support ever since the foundation of the Society, as well by papers
