size and thickness, and with the muscular impressions strongly 

 marked. The incomplete state of the only cranium that admits of 

 any measures at all b'eing taken precludes any accurate statement 

 of its dimensions. One of the most remarkable parts of the col- 

 lectiop. of human bones is found in those belonging to the lower 

 extremity. These are very numerous, and they may be computed 

 to have belonged to at least thirty-five or thirty-six individuals. 

 There are portions of about thii'ty thigh bones, and from 

 eighteen to twenty tibise, but portions of only three fibulae have 

 been preserved. Not only are these bones very numerous, but some 

 of them present such remarkable characters as to demand especial 

 attention. In the first place, omitting the very young or immature 

 bones, the long bones of the lower extremity exhibit great diversity 

 iti size, about one-half of the number being-of a comparatively largo 

 type, and the others small, in which respect they correspond with 

 many other bones above noticed. One of the most remrirkable 

 characters presented in the thigh bones is the enormous deve- 

 lopment of the linea aspera, which forms a sort of prominent 

 ridge or keel of great height and thickness, and extending from one 

 end of the bone to the other. In several of the bones this pro- 

 minent keel is enormously developed, so as to give the bone an aspect 

 altogether unlike the human. Five of the larger thigh bones are 

 thus formed, and four of the smaller sized ones. Bat a still more 

 remarkable character is presented in about one half of the tibisB or 

 leg-bones. These are so much compressed, though perfectly 

 straight, as almost to have lost resemblance to the normal human 

 tibia. To this peculiar conformation the term " platycnemic" 

 might conveniently be applied. Mr. Busk remarked that bones 

 of similar conformation had been met with in several places in 

 France, in ancient tumuli and elsewhere, and that he had liimself, 

 in company with Dr. Falconer, noticed well-marked instances of it 

 in some human bones in all probability belonging to the Eeindeer 

 period, and contained in the valuable collection of the Cure of 

 Bruniquel. He had also noticed the same character in some bones 

 from a limestone fissure at Mewslade in South Wales. The human 

 and other remains found iu the " Judges' Cave" were next de- 

 scribed : — About twenty years ago, Sir James Cochrane, the pre- 

 sent Chief Justice of Gibraltar, discovered in his own garden, under 

 a considerable thickness of soil, the entrance into a vertical fissure, 

 which, after descending to a depth of about forty feet, ended in a
