The Contrast of Practice and Theory. 33 



consequences of theory, that is, the power to answer what are 

 equivalent to examination paper questions, is of value mainly 

 in proportion to the degree in which a fairly simple theory is 

 able to deal with practical data ; and in most practical matters 

 a moderate, very moderate, acquaintance with such processes of 

 deduction, if combined with a careful and strict attention to the 

 questions, What are the real data, neither more nor less, assumed ? 

 and, What sort of consequences can be deduced from those data, 

 neither more nor less ? is what is really necessary to clear the 

 ground, and enable us to judge in what direction to look for 

 the sources of the inevitable contrast between Practice and 

 Theory. 



The Honorary Secretary (Mr. Robert M. Young, B.A.) 

 announced to the meeting that Mr. Robert Lloyd Patterson, 

 J.P., F.L.S., had given to the Society a very large number of 

 the valuable publications of the Royal Society, London. He 

 had also presented them with about forty fine specimens of 

 native birds.
