PREFACE 



It is under a feeling of great responsibility that 

 the author lays before the profession his views 

 on one of the most difficult subjects connected 

 with veterinary science. 



The lectures were delivered at the Royal 

 Veterinary College, Edinburgh, during the 

 summer session of 1874. 



They are for the most part based on the 

 teachings and practice of the late Professors 

 Dick and Barlow, but have, the author ven- 

 tures to hope, a further value in being based 

 also on the notes and observations of about 

 five hundred cases of horse examination by 

 the author himself. This is exclusive of the 

 extensive experience gained by the author as 

 the pupil of one of the busiest practitioners 

 in Yorkshire for a period of nearly four years.
