to Ilia probable stature correspond more nearly with those observed in Negro than 

 in European skeletons. Similar measurements made on a number of skeletons of 

 the prehistoric and early empire period show in most cases the same correspond- 

 ence. I5iit further research is here necessary. 



6. Falteolithic Implement lollh alleged TIcong-marks, 

 By Miss Nina F. Layakd. 



This line Palaeolithic hatchet was found in Levington Road, Ipswich, at a 

 depth of about five feet. In the natural depressions of the flint the original 

 surface of the nodule escaped being worked away when the hatchet was shaped, 

 leaving a rough surface. This surface consists of more than one layer, the outer- 

 most of which appears to have been removed by friction. 



7. On a Piece of Yew from the Forest Bed on the East Coast of JEngland, 

 apparently czit by Man. By F. D. LoNGE. 



This object was found by the author with other pieces of yew in a section of 

 cllfi" exposed after a high tide iu the Kes.siugland Freshwater Bed, belonging to 

 the Cromer Forest Bed Series. Some days afterwards, in cleaning the piece of yew, 

 ho discovered two oblique cuts upon it, made by some implement much sharper 

 and thinner than the large manufactured instruments (Palaeolithic or Neolithic) 

 with which we are familiar. He believes that the circumstances exclude the idea 

 that these cuts are of recent oriain.

9. 071 the Temporary Fissures of the Human Cerebral Hemisjiheres, with 

 Observations on the Development of the Ili2}pocampal Fissure and 

 Ilippocampal Formation. By Professor J. Symington, M.D., Queen's 

 College, Belfast. 



_ This pai)er discussed the views recently published by Ilochstetter, who main- 

 tains that the so-called temporary or transitory fissures of the human cerebral 

 hemispheres, which have been described by "so many anatomists as existing 

 towards the end of the third and during the fourth montbs of fretal life, are not 

 present in the fresh brain, but are the products of commencing maceration and 

 putrefication. Professsor Symington admitted that the frequency of the occur- 

 rence and the depth of these fissures had been exaggerated, but he showed a 

 number of photographs of specimens, botli macroscopic and microscopic, in support 

 of tlie view that they did occur in Avell-preserved material. He admitted, 

 liowever, that the arcuate fissure, even if luit an artificial product, had no 

 morphological significance, and that its posterior part had nothing to do with the 

 Ilippocampal fissure. He also exhibited a series of sections of the brain of a 

 human fostus in which the hippocampal fissure and the hippocampal formation 

 could be traced from near the temporal pole of the hemisphere upwards and 

 forwards towards the frontal end of the brain dorsal to the developing transverse 

 commissures. 



Attention was directed to the interest of these facts in connection with the 

 position of the hippocampal fissure and formation in the marsupialia and mono- 

 tremata where they occupy a similar position throughout life. These observations 

 also support the opinion, hitherto based mainly on comparative anatomy, that the 

 rudimentary grey and white matter existing on the dorsal aspect of the adult 

 human corpus callosum is the remains of a hippocampal formation.
