62 PRESIDENTIAL ADDRESS SECTION B. 



that there also resides a repulsive force preventing compression and 

 varying as the inverse tenth-power of the distance, so we see that 

 Crystallography also is being swallowed by Physics just as Chemistry 

 has been, and this unification of the Sciences is all to the good. 



In conclusion I have to apologise for being unable personally 

 to represent some of the other Sciences comprised in Section B. I 

 invite the attention, however, of the devotees of that non-experi- 

 mental Science Geology to the possibility that some of their 

 cherished replacement theories may have to go to the wall — in 

 other words that what appears to be replacement may be trans- 

 mutation. Thus carbon appearing* in silica is very easily explained 

 if silicon nucleus is CHe 4 , as I suggested in 1909. So if zirconium- 

 nucleus is C Ne 4 , titanium Si Ne and niobium N Ne.j their genesis 

 becomes easily understood. The pressures in the interior of the 

 earth may be sufficient to overcome the repulsive force in the atoms 

 (even though as already said it varies as 1/d 10 ) and thus transmute 

 them by simple squeezing. Such minerals as the trio SrS0 1 , YPO, 

 and ZrSiO, could be changed into one another quite easily on this 

 theory, since the number of hydrions is the same in all of them. 

 When I have come across an ordinary geological theory I 

 have always felt like Cato, "Semper miror quod non rideat 

 haruspex baruspicem quum viderit," so when Geologists meet and 

 ?ee one another here in this section I hope they will take the hint 

 f.nd wink discreetly.
