the diluvium containing the bones of the Irish Elk, Mammoth, 

 &c. to that of England ; and that the last of the Moas was 

 destroyed by the earliest inhabitants of New Zealand, as the 

 Dodo was extirpated by the Dutch colonists of the Mauritius, 

 and the Irish Elk by the early British or Celtic tribes. 



Prof. Wyman remarked, that so far as variations of form 

 in particular bones are indicative of specific characters, the 

 specimens in question appeared to belong to a hitherto 

 undescribed species. In the Troglodytes gorilla recently 

 presented to the Society however, the humerus differed as 

 much from that of the specimen belonging to himself as 

 from a human humerus. It is probable, however, that in 

 birds there is less variation in individuals from the type 

 of the species. 



Dr. Cabot moved, seconded by Dr. Gould, that Mr. 

 Cross, the donor of these valuable specimens, be elected a 

 Patron of the Society. Voted unanimously. 



Dr. C. T. Jackson read a paper containing an Analysis 

 of the body and scales of a species of Palaeoniscus from the 

 Albert Coal-Mine, in Hillsborough, New Brunswick, with 

 an account of the processes by which it was made. 



The following results were obtained. 



Animal matter, .... 0.0800 



Carbonate of lime, .... 0.0980 



/- Phosphoric acid, .... 0.2452 



\ Lime, 0.1234 



I Magnesia, 0.0623 



Silicious matter, 0.0040 



0.6129 



The original amount of matter operated upon was 0.620 

 grammes. The loss of seven millegrammes took place in the 

 solution of the phosphates that had been fused with Carbonate 

 of soda, and could not materially affect the accuracy of the ana- 

 lysis.
