MULTIPLE NEUROMATA OF THE CENTRAL NERVOUS SYSTEM. 769 
smaller patches are also visible in the neighbourhood of the lateral fillet upon one 
side, and a number of smaller ones may be detected amongst the transverse fibres 
of the pons towards their more superficial bundles. A narrow elongated patch is also 
to be seen amongst the deeper part of the fibres on one of the 5th nerves. 
Uprer Part or Pons Varoui—“< D.” 
The number of patches has increased very greatly at this level, no fewer than 
twenty-one being found in one section. The largest of these is lozenge-shaped and is 
situated in the middle line anterior to the posterior longitudinal fasciculus, and midway 
between it and the trapezium. Within the fibres of the trapezium itself, three smaller

patches may be detected, and still other three, also small in size, lie in the reticular 
formation, just posterior to the trapezoid fibres. Another is found at the cerebello- 
pontine angle. The remainder are scattered throughout the transverse fibres of the 
pons, mostly amongst the more superficial of these fibres, but not limited to them. 
Their exact positions may best be seen from the accompanying figure. 
Upper LeveL or MrsenceEPHALON—“ FE.” 
The patches at this level are very few in number, and are limited to the region of 
the crus cerebri, only one of which is affected. The largest patch implicates the fibres 
of the 3rd nerve just at their point of emergence, the area affected being, however,
