Meteorological Observations. .327 



arose from an acid secretion, capable of being emitted at pleasure by 

 the animal, but so far without success. 



I hope these few observations will be the means of directing the 

 attention of naturalists to this subject, which has hitherto, I believe, 

 escaped their notice. 



Brown Street, Cork, March 4, 1843. Francis M. Jennings. 



Mr. Jennings having sent the foregoing to me to forward for pub- 

 lication, I beg to add, that I repeated his experiment with a similar 

 result to that he describes. I understand that Mr. Armstrong of 

 this city, having, in collecting Ancyli, put some of them into his 

 mouth, experienced the same painful action from the contact of 

 these animals with his tongue. As I am not aware that the subject 

 is rightly understood, I think it worth bringing under notice.
