 Lectures merely exhibit types of the way in which different 

 classes of facts are approached, the special difficulties

The Delegates desire to express their sincere thanks 

 to Mr. Brown for his suggestion, and to Mr. J. L. 

 Myres, M.A., Student of Christ Church, for his energetic 

 assistance in working out the scheme.
