ed more or Jess with general scientific principles ; and we may anti- 
cipate still more extended researches. 
23. Belfast Natural History Society.—It appears from the min- 
utes of the proceedings of the Society, (June, 1834,) that it isin a 
course of successful exertion. It has a fine building, a moderate 
revenue, without debt ; a museum and library already very conside- 
rable, and a sure fund in the zeal and activity of its members. 
24. Ichthyosaurus, fossil fish, wood, &c.—Extract of a letter to 
the Editor from England, dated May 12, 1835.— Miss Mary Ann- 
ing, the female geologist is reported to have discovered the largest 
Ichthyosaurus ever found. This gigantic animal must have died and 
its bones fallen abroad at the decomposition of the body, just before 
they were covered with the lias. The bones lie in the marl as is 
usual. This animal I understand, must have been at least thirty five 
feet in length and of considerable breadth: the one I possess must 
have been twenty eight feet. 
The collection in the British Museum, is now very fine. We 
have just completed our museum in Newcastle upon Tyne, which, in 
the Fossil Flora, much exceeds any in the kingdom. Mons Agas- 
siz, lately selected from my museum thirteen varieties of *magnesian 
fossil fish (which he had never seen before) for his new and beautiful 
work. He is a most intelligent man. 
Among the fossil woods which you were so good as to send me, 
the one from south of Lake Erie, was dicotylidonous. 
* From the formation of the magnesian limestone.
