courses forward, penetrates the firm connective tissue behind the nasal 

 capsule, then rises and is applied more or less closely to the most 

 medial bundle of the olfactorius, with which, however, it does not an- 

 astomose and from which it can be easily distinguished by its texture. 

 It terminates in a cellular aggregation at the extreme end of the nose 

 on the dorsal wall of the external nares. The internal course is not 

 stated in this notice. 



Free Nerve Termini in the Epithelium of Lumbricus. 1 



Both Lenhossek and Retzins after the most exhaustive study af- 

 firmed that free nerve ter- 

 mini do not occur in the 

 skin of the earthworm. Dr. 

 Smirnow, however, finds by 

 a modification of the rapid 

 Golgi process very numer- 

 ous, extremely fine, usually var- 

 icose free termini in the epithel- 

 ium of the skin and the mucous 

 membrane of the mouth cavity 

 and oesophagus. The accomp- 

 anying diagram, copied from

Degenerations of the Brain and Spinal Cord. 



Two papers abstracted in the Proceedings of the Royal Society 

 (March i, 1894) contain much of value for the anatomist and the 

 surgeon. 



The first, 2 as a result of excision of the foci for the movements 

 of the thumb and hallux from the cortex of the monkey, presents the 

 following conclusion : It seems probable that a second decussation 

 lower down in the cord — recrossing — does not occur, and that the bi- 

 lateral degeneration observed by Pitres, Sherrington, Langley, Mura-
