cal teaching at the bedside in the Infirmary of Edinburgh. 
At the same time he directed all his leisure to the improve- 
ment of the museum under his charge. His lectures were 
eminently successful, and he devoted a certain portion of his 
time to giving demonstrations of anatomy in addition to his 
professional labours as a lecturer. In these demonstrations 
the microscope was constantly employed, and in the nume- 
rous papers which he subsequently published we find him 
making extensive use of this instrument. He based his 
physiological and morphological teachings on an accurate 
knowledge of the nature of the tissues which entered into 
the composition of the organs of the animals, and these alone 
could be understood by researches dependent on the aid of 
the microscope. Had he lived, Goodsir would have undoubt- 
edly put his large knowledge of the laws which govern the 
functions and forms of animal life into a systematic treatise. 
As it is, we have from his pen a series of papers unrivalled 
in accurate observation and felicitous induction, and no one 
who wishes to master the results of biological science can 
dispense with the study of his writings. This work, em- 
bracing his most important papers, has been carefully edited 
by his successor in the Chair of Anatomy, Professor W. 
Turner, and contains a large series of plates illustrating 
the various structures to which reference is made in the 
text. To his large class of pupils, to students of minute 
structure, and the cultivators of physiological science, these 
volumes will be found a precious record of the observations 
and views of one of the profoundest physiologists this cen- 
tury has produced.
