throughout the whole length of the cord than is afforded by the 

 figures in the Atlas. Those illustrating the grey matter in the motor 

 horn and the nerve cells are distinguished by a softness and delicacy 

 of character which are most pleasing. One cannot, however, but feel 

 that if the author had arranged his plates so as to have given a some- 

 what higher magnification of the motor cells, the reader would have 

 been in a better position to appreciate the demonstration of their 

 number and disposition in each segment. 



In the introduction of fifteen pages Dr Bruce describes the method 

 which he pursued in the investigation, and gives an account of the 

 form of the grey matter, and the number and arrangement of the 

 motor cells in the different regions of the cord. By the aid of this 

 Atlas observers ought to have no difficulty in identifying any segment 

 of the cord in the examination of transverse sections through it, and 

 the figures will be a great boon to pathologists in the study of the 

 changes which take place in this organ as a result of disease. 



From the attention which, as is well known, Dr Bruce has paid to 

 the tracts of nerve fibres in the columns of white matter, we may 

 hope that he will, in due time, produce an Atlas in illustration of their 

 position and extent comparable with the one now before us on the 

 grey matter.
