Geological Restdts of the Boring of an Artesian ivell at Atlantic 

 City, N. J. Mr. Lewis Woolman stated that there was commenced 

 in the summer of 1886 at Atlantic City, N. J. an artesian well, the 

 drilling of which has been since continued with some intermission 

 until, at the present time, a depth of 1121 feet has been reached. 

 During a recent cessation in the work caused by delay in the re- 

 ceipt of pipe for tubing the well he had been jjermitted through the 

 courtesy of the gentlemen interested in the enterprise to turn over 

 and examine the sands, clays and marls accumulated in the dump 

 heap and had found many fossil representatives of life forms, 

 including a bone the articulating end of a femur or humerus of 

 an animal belonging to the Crocodilia, presented by Dr. T. K. 

 Reed, and a few shells and fish teeth presented by Jas. H. Moore, 

 engineer in charge. There have been obtained from the well 52 

 species in all, 42 being mollusks. Many of the smaller shells were 

 entire and quite perfect but most of the larger ones were fragmentary, 

 having been broken in pieces by the drill. James H. Moore also 

 kindly furnished a minute description of the thickness and charac- 

 ter of all the sands passed through, by a careful examination of which 

 and a grouping of the smaller seams with the larger ones that give 

 character to formations, the speaker had constructed the following
