where they are flask-shaped. The other layers reach their maximum de- 

 velopment around the fovea at successively increasing distances from its 

 centre. From the inner ends of the cones, fine fibres proceed obliquely 

 from the outer to the inner surface of the retina in a radial direction from 

 the centre of the fovea to the periphery of the retina. These fibres con- 

 nect the cones with the cells of the outer granule-layer ; they next form a 

 thick plexus at the inner surface of this layer, which I term the cone-fibre 

 plexus ; then traverse the inner granule-layer, in which they connect them- 

 selves with round and roundly oval cells, and are continued through the 

 medium of the ganglion-cell-like cells of this layer into the granular 

 layer, where they join the processes directed outwards from the cells of the 

 ganglionic layer. Thus they constitute an anatomical path between the 

 cones and optic nerve-fibres. 



These oblique nervous fibres are crossed by vertical fibres of modified 

 connective tissue directed radially from the centre of the eyeball. Around 

 the fovea the connective fibres traverse the cone-fibre plexus and the 

 outer granule-layer in the form of stout vertical pillars corresponding to 

 those which in the turtle I named the outer radial fibres ; while in the 

 thinner periphery of the retina, the vertical, connective-tissue fibres are 

 finer, and traverse all the layers between the inner and outer limiting mem- 

 branes. 



The pecten lies excentrically at 1'" from the centre of the fovea. Its 

 minute structure agrees with that of the Gecko's. 



The distribution of the optic nerve-fibres with respect to the fovea 

 resembles that which obtains with reference to the yellow spot in the 

 human eye. 



XVIII. " Additional Varieties in Human Myology." By JOHN 

 WOOD, F.R.C.S., Demonstrator of Anatomy in King's College, 

 London. Communicated by Dr. SHARPED Received June 9, 

 1865. 



In the past winter session thirty-six subjects have been dissected in the 

 Anatomical Rooms at King's College. In them the author has directed 

 especial attention to the combinations of muscular aberrations in the same 

 individual, with a view to obtain data for ascertaining any relation that 

 may subsist between such abnormalities in different parts of the body. 



In one subject, a muscular man about 5 feet 8 inches high, with promi- 

 nent features, aquiline nose, somewhat high cheek-bones, well-pronounced 

 chin, and good skull-development, an extensive departure from the ordinary 

 type was observed in every part of the body, the abnormalities being more 

 numerous than in any other subject previously noted. 



In the neck, on both sides, was a well-developed and powerful levator 

 claviculce, in all respects like that first described and figured by the author 

 in a paper read last year before the Royal Society. It was connected
