FOVEA CENTRALIS OF THE HUMAN RETINA.

Fig. 2. Three cones from the centre of the fovea, with outer granules lying in their 
diverging primitive fibres, X1300. 
Fig. 3. Cones and outer granules from near the margin of the fovea. The inner seg- 
ments of the cones are coarsely granulated ; three include outer granules, and 
all produce a fibre which runs obliquely inwards through the outer granule- 
layer, X1300. 
Fig. 4. A vertical section showing the passage of the primitive fibres of the cone-fibre 
plexus into the inner granule-layer midway between the centre of the fovea 
and the margin of the macula lutea, X1300: a. horizontal band of inner 
bundles of the cone-fibre plexus detaching fibres which traverse 5, a finely 
areolated band lying between the plexus, and c the inner granule-layer ; d , an 
inner granule in one of these fibres. 
Fig. 5. A vertical section through the inner granule-layer near the edge of the fovea, 
X1300: a, the granular band marked b in the preceding figure; b, the 
smaller granules; c, the larger granules; d, obliquely directed bacillary fibres 
with which the granules are connected. 
Fig. 6. A vertical section through the inner layers at the centre of the fovea, X1300: 
a, inner granules imbedded in areolated connective tissue ; b, ganglion-cells. 
Note . — In order to include these figures in one Plate they have been much reduced 
from the size of the original drawings, the fine outlines and delicacy of which can scarcely 
be reproduced by lithography.
