 hours during which, within these halls, the learned speech of 

 professors may be heard or slumbered through. Our meet-

 that is to be found in our community; and since they are to

 among us of enthusiasm for the things of the intellect, and 

 for the production of a keener sense of the true interesting-

 game which the most highly endowed part of the race has 

 been playing throughout all history, — the struggle to under-

 to the occasion of its delivery, have been abridged, and the subsequent 

 part has been much altered and amplified.
