It does not appear that phosphorus exerts any very powerful 

 operation on the uterus, as in this instance no symptoms of abor- 

 tion were the consequence of so large a dose, notwithstanding 

 the spasms which formed part of the symptoms.

CIRCULAR, 

 FROM THE GEOLOGICAL SOCIETY OF PENNSYLVANIA. 



Sir, — The Geological Society of Pennsylvania, do themselves 

 the honour of transmitting you a copy of their Circular, and 

 ask you to co-operate with them in promoting the objects they 

 have in view. 



To have an exact knowledge of the mineral resources of this 

 state, is considered the most important of these objects, and as 

 it is the intention of this Society, to construct, as soon as the 

 proper information is obtained, an accurate Geological Map 

 which shall indicate the mineral topography of the State, you 

 are respectfully requested to return at your earliest leisure, an- 

 swers to the following queries, and to assist in giving effect to 



hibifeJ lioth light and the smell of phosphorus, when heated. This convinced 

 Citizen S. that there could be only one cause for all these eflects, and that they 

 were all produced by the circumstance of his having, four or five days before, thrown 

 out some water through a casement into the poultry yard; which water had served 

 to wash and purify several substances, on which operations of phosphorus had 

 been performed. The phosphorus contained in these waters, in a state of nature, 

 he considered as solely occasioning the death of such a number of domestic 

 animals.
