greater elevation than that already attained, viz. : 253 feet above Lake

While the above mentioned facts are still in mind, it will be con- 

 venient to speak of the Palmyra " oil well." A failure as a source of

 Artesian wells in that and similar situations. The following is the rec- 

 ord kindly furnished me by Dr. Lapham :

 Michigan (828 feet above the sea).
