The curious dip, F,in the median line or keel in front of the dorsal plane, , is apparently notaccidental (though perhaps the worker has accidentally made it larger in thisimplement than was intended), since we find also in the Norwich test specimen aslight concavity in the cariual line just in front of the dorsal plane {see thefigures in Plates II and III, showing lateral view). This concavity wouldcertainly have assisted the owner of the flint-implement in binding it by a thongto such a ^-shaped handle as is used for mounting chipped stone weapons by someexisting savages. 14 Sir Eay Lankester.—Description of the Test Specimen of the IV.
