ADVKRTISEMENT. 



which the Science of Comparative Anatomy has been enriched 

 since 1844, and by adding details which the time allotted to 

 the Hunterian course compelled me to omit in the theatre : 

 but I have been careful to preserve the scope and opinions of 

 the original Lectures, and, as far as possible, the very words in 

 which they were delivered. 



The Volume concluding the Course will, I hope, appear in 

 the earlier half of the ensuing year. 



London, 1846.
