He had ascertained the following species by the aid of Brong- 

 niarfs Fossil Ferns, viz. Sphenopteris Dubuissonis ; Pecopteris 

 cistii ; P. Serlii ; P. punclidala. There were some species of Neu- 

 ropteris, one of which appeared to be N. acutifolia, and another 

 N. Scheuchzeri ; also one species of Odontopteris, but none of them 

 perfect enough to be identified. Three or four of these were iden- 

 tical with species found at Wilkesbarre, and figured by Brongniart. 

 He spoke of the abundance and beauty of the Ferns to be found 

 at Mansfield, and hoped other members of the Society would give 

 them attention. 



Dr. C. T. Jackson alluded to the singular position of the 

 fossil remains at Mansfield, and stated that the coal strata 

 had been completely inverted by a force acting from be- 

 neath on the centre of the strata. 



Dr. Storer reported upon some numbers of the Calcutta 

 Journal of Natural History which had been committed to 

 him for that purpose. 



He also read an interesting Letter from Dr. Wyman at Paris, 

 and presented a very perfect skeleton of a mole which Dr. W. 

 had bought to replace one which he had formerly broken. 



Dr. Abbot stated that Mr. Teschemacher had deposited 

 with the Society two swans which had died suddenly at 

 the Conservatory, and which were to be mounted. 



In the pro-ventriculum were found some leaves of JSerium ole- 

 ander ', and Mr. T. did not doubt that their death was caused by the 

 poisonous qualities which that plant possessed in common with 

 many belonging to the family Apocynese, particularly the cele- 

 brated Upas Tree of Java. 



Dr. H. C. Perkins of Newburyport presented a cast of 

 the fossil femur of the Orycterothcrium Oregoiiense. 



Dr. J. P. Spooner of Milton, presented a Collection of 

 Plants from the vicinity of Milton, made by D. C. Field. 



The thanks of the Society were voted to Drs. Perkins 

 and Spooner.
