 we may sometimes be tempted to undervalue and even to 

 smile at some of the knowledge which passed for science 250 

 years ago ; but we must remember that to start anything 

 that ultimately proves worth having is a much more difficult 

 thing than merely to elaborate something already in existence 

 — the man who draws an original beautiful pattern out of his 

 head shews much greater talent than he who copies it with a 

 few improvements. Even in our own time scientific ideas 

 have vmdergone great changes by such discoveries as that of 

 radium, and there is no knowing how much the next genera- 

 tion of scientists may scorn the science of 1913, through fresh 

 wonderful discoveries. In one way the early members of the 

 Royal Society differed much from more recent ones — there was 

 comparatively little specialism, but each took a general 

 interest and probably knew a good deal ubout other things 

 besides his own special hobby. Now specialists seem 

 necessary if any new discoveries are to be made, for the mass 

 of information and literature in all branches is so enormous 

 that no man could probably master it all, and could do but 

 little unless he confined himself to that branch. But it is a 

 misfortune that it must be so, for you cannot draw a
