He also offers that, in case of their being not less than three 

 competitors whose performance shall be judged to be such as would 

 deserve the honour of a prize, if one were available, he will give 

 A Second Prize of ios. 6d. for the Second Best Essay and Oral 

 answering on that subject. Professor Thomson is to be himself 

 the examiner, and to have the decision, unless he gets some well 

 qualified person or persons, as for instance the Professor of 

 Mathematics, or of Natural Philosophy, in the Queen's College to 

 act with him, or, to act instead of him, in the decision. No prize 

 is to be awarded unless very satisfactory merit be exhibited. If 

 one or both of these prizes be not awarded, Professor Thomson 

 will arrange to have the amount reserved for one or more prizes for 

 the succeeding Session, on terms to be afterwards prescribed. 



As the primary object is to encourage Members of the Field 

 Club to acquire knowledge on the subject proposed, intending 

 competitors are to be perfectly free to seek and to receive aid from 

 books or from any persons towards acquiring information; but 

 not unacknowledged aid in the composition or revision of the 

 Essay, or of passages in it. The Essays are to be given in to the 

 Secretaries of the Club, on or before the 17th March, 1871.
