Steno's 1 firft con je&ure concerning thefe matters: Thai they are 

 always found in the fame place, of the fame confidence ; and that there 

 arenofigns amongft them of fooneror later production. 



92. And To do the Ophiomorphit's found in a bluifh clay in the 

 Parifti of Great Rolwright, Eaftward from the Church, whereof 

 fomeare fo foft, that 'tis eafleto pfefs them afunder with ones 

 fingers; and others a hard bluifi fione. But though they agree 

 with the former in the manner of production, they differ as much 

 in the manner of their lineations, for whereas their lri# were di- 

 vided near the rim, fomeof the lineations of thefe come toge- 

 ther there, and are united in pretty large protuberant knobs on 

 each fide the back of the done, which in thefe being broad and 

 fomwhat rifing, is croffed by other arched lines that intercede the 

 eminencies, as in Fig. 13 



93. Other Ophiomorpbifs there are, that have only ftraight 

 iingle ribs, which terminate alfo in ftraight ridges that run along 

 on each fide the back of the ftone ; between which two ridges, 

 there rifes a third more prominent one, juft in place as it were of 

 the Spina dor fain, as in Tab. 5 . Fig. 14. which though not wreath- 

 ed, but plain like the other lower ridges on each hand it, I take 

 to be the Cornu Ammonhs criflatum of Johannes Baukinm m . One 

 of thefe, of about four inches over, and made up of as many 

 turns,\vzs given me by the Reverend and Learned Dr. John Wallit ; 

 and there is another amongft the K^'a^o, f the Medicin School, 

 of above eight inches diameter, taken up as they fay fomwhere 

 abou: Corpus CbrisJi College. 



94. There are alfo Orphiomorphit's found fomtimes about 

 Adderbury, about two miles from Banbury, but fo very feldom, 

 that though I were there often, I could meet with none of them ; 

 fo that I cannot inform the Reader whether they are of any pecu- 

 liar kind, different from what have been already defcrib'd,or no : 

 However, that the Town has not its name from thefe ftones (as 

 Mr. Ray thinks) I dare confidently avouch, Adderbury being only 

 the vulgar name : for in the Court Rolls of New College, (and o- 

 other Inftruments) to which the Lordfiip of the Town belongs,it is 

 written Eabberbury, perhaps from St. Ebba the tutelar Saint of the 

 Church.
