122 PROCEEDINGS OF THE ANATOMICAL AND ANTHROPOLOGICAL 



NOTES UPON A MESIAL SAGITTAL SECTION OF A FEMALE 



SUBJECT. 



By Professor E. W. EEID, M.D., F.E.C.S., President of the Society. 



This section was one of a series of four sagittal sections of the 

 trunk of a well-developed muscular female subject, aged about thirty- 

 five years, which was brought to the Anatomy Department of this 

 University. The only history which I was able to obtain was that the 

 individual was found in an outhouse in this town in an insensible and 

 moribund condition and that she died a few hours afterwards. 



As the body seemed to be very well formed and of an age younger 

 than that which usually obtains with regard to dissecting-room sub- 

 jects, I decided to make sagittal sections of the trunk in the frozen 

 state. 



As the mesial section shows some remarkable features I think 

 that it is desirable that they should be put on record. 



On looking at the head the cranial vault is seen to be particu- 

 larly thick. The internal occipital protuberance is on a higher level 

 than usual, causing the tentorium cerbelli to assume a practically 

 horizontal position instead of to slope downwards and backwards 

 as it ordinarily does. 



The spinal column presents twenty-three presacral, six sacral and 

 three coccygeal vertebra?, the effect being to shorten the lumbar and 

 lengthen the sacral region. The levels of the viscera in relation to 

 the front of the spine are about half a vertebra higher than usual. 

 The contents of the spinal canal are of interest, more especially 

 from a morbid anatomy point of view. The spinal cord, which ter- 

 minates infcriorly at the usual place, is compressed antero-posteriorly
