and later, with some additions, in the thirty-seventh bulletin of the 

 Jersey Society. The following embraces the gist of these reports, as 

 well as of the writer's own observations.^ 



The teeth are in an unexpectedly good state of preservation, only 

 the terminal parts of the roots being broken away. Their color is 

 dark brown, with grayish white somewhat chalky looking crowns. 

 All show advanced degree of fossilization. The apices of the cusps 

 were worn away in life and the finer architecture of the crown is 

 as if faded, probably through corrosive action of the moisture in the 

 deposits that enclosed the specimens. 



Five of the teeth, namely, a second left premolar, a first right and 

 a second left molar, and the right and left third molar, with a part 

 of the root of left incisor, belong to the upper jaw, while seven are 

 from the lower jaw, being respectively a canine, first and second pre- 

 molar with second molar of the left side, and a second incisor with 

 second and third molars of the right side. All are probably from the 

 same set and their characteristics are such that the ancient man they 

 represent must be ranked anthropologically as one of the most primi- 

 tive yet discovered. 



The illustration on plate 63 shows a reconstruction of the upper 

 and lower dental arches of the St. Brelade man, by Keith and Knowles, 

 and the upper arch in the jnodern human skull, after Cunningham. 

 It is seen at a glance that the Jersey teeth are larger than the modern 

 in every direction and that in consequence the dental arches themselves 

 must have been considerably larger. 



Another feature in which the Jersey teeth differ even more radi- 

 cally from the recent, is their extraordinarily stout roots. The diam- 

 eters of the neck and roots of the Jersey teeth are almost equal to 

 and in some cases exceed those of the crown, indicating that rela- 

 tively great requirements were made on the teeth by the quality and 

 possibly also quantity of the food. Such roots indicate unmistakably 

 strong muscles of mastication and a stout massive lower jaw, prob- 

 ably somewhat smaller but scarcely less powerful than the still earlier 

 Mauer mandible. 



Mn June, 1912, the writer visited Jersey to examine the original teeth and 

 to visit the cave where they were discovered, and he wishes warmly to thank Mr. 

 Sinel and Dr. Dunlap for the courteous treatment and facihties which they ex- 

 tended to him on this occasion, as well as to Captain Rybot, of the 76th Punjabis, 

 for his service in furnishing excellent sketches of the locality. In 1923 the writer 

 revisited Jersey and the cave with Professor Marett, whose great courtesy is also 

 hereby gratefully acknowledged.
