APPENDIX I 429 



come sufficiently close to your father's, he shall give his 

 work due recognition and publicity.^ 



Among his schemes of the early '80's, there was actually 

 commenced a work on the principles of Mammalian 

 Anatomy and an Elementary Treatise on the Vertebra ta. 

 The former exists in the shape of a number of drawings 

 with very brief notes, the latter to a slight extent only 

 in MS. In the former, intended for the medical student 

 and as a means of familiarising him with the anatomical 

 " tree " as distinct from its surgical " leaves," your father 

 once again returned to the skull, and he leaves a scheme 

 for a revised terminology of its nerve exits worthy his 

 best and most clear - headed endeavours of the past. ^ 

 And well do I remember how, in the '80's, both in the 

 class-room and in conversation, he would emphasise the 

 fact that the hypoglossus nerve roots of the mammal arise 

 serially with the ventral roots of the spinal nerves, little 

 thinking that the discovery by Froriep, in 1886, of their 

 dorsal ganglionated counterparts, would establish the 

 actual homology between the two, and by leading to the 

 conclusion that though actual vertebrjB do not contribute 

 to the formation of the mammalian skull, its occipital 

 region is of truncal origin, mark the most revolutionary 

 advance in cranial morphology since his own of 1856.

 Peripheral Distribution of certain of the Cranial Nerves of Mustelus 

 Isevls" by Edward Phelps Allis, junr., reprinted from Quart,

^ Concerning this he wrote to Professor Howes in 1890 when 

 giving him permission to denote two papers which he was about to 

 present to the Zoological Society, as the first which emanated from 

 the Huxley Eesearch Laboratory: — "Pray do as you think best 

 about the nomenclature. I remember when I began to work at 

 the skull it seemed a hopeless problem, and years elapsed before I 

 got hold of the clue." 



And six weeks later, he writes : — " You are always welcome to 

 turn anything of mine to account, though I vow I do not just now 

 recollect anything about the terms you mention. If you were to 

 examine me in my own papers, I believe I should be plucked."
