an(T others which I procure<l nt Ipswich. ^Vniong those are- 

 teeth of CarrharoiJon meijalofhm. The Inrfrest is not hirger 

 than the medium size of the South Carulinft collection. The- 

 largest of the English are 3 inches from end of root to apex p 

 the American 5 inches. With the last we have associate*! teeth 

 of Sinaller species — j)igmaean teeth, not larger than the tenth- 

 of an inch. Large Shark's teeth are also found in calcareou* 

 deposits of Malta. Of these we have also specimens. 



66. With the exception of a few of the largest Carcha- 

 rodon ma/nlodmi (teeth), which were prtsentec^ by Southern 

 States friends, our collections were derived from cargoes, bound 

 for England, the vessels having to con^e to Halifax for repairs^ 

 The first and best cargo was that of the barqwe Northiinibrian^ 

 which was unloaded on Bennett's wharf, in order that the ship- 

 might be pepniped. The cargo v/as in the rough, having bceni 

 taken out of tlie sea and put on board by negroes. From the 

 captain and mate I received the molars of mammoth and 

 mastodon. Other specimens I collected by daily visits to the- 

 cargo on the wharf. I thei-eby got together a fairly representa- 

 tive collection. On cue of ray visits I vas surprised by finding- 

 a flint spear head, of good shape, when looking fur fossils. 

 Tills had other evidence of having been assoeinted with 

 Cardiarodhn megufodon besides its position in the cargo and its 

 coat of clay. The bases of Ralnni are firmly attached to both, 

 showing that both had occupied a submarine position. I con- 

 nected the two then, and they have continued so until the 

 present. This conjunction was perplexing. The queries arose ? 

 When did the two become associated in the deposit 1 And by^ 

 what means ? The conelusron at which I arrived is this, thafe 

 the spear h«ad had been originally in a surface deposit which* 

 overlay the phosphatic bed, and that the sea had subsequently* 

 washed this with other contents of the superficial deposit 

 among the fossils beneath. At the American Archfeologisb 

 Conventidn, held during the Centennial Exhibition, Phila.^ 

 1876, I submitted the tooth and spear-head Avith my perplexities 

 and conclusion. It was agreed that the conclusion at which I 

 had arrived was the proper one. I have in my glacial investiw
