 length. This is an idea of which great use has 

 been made in the mathematics but none in the

making is tantamount to assuming that such 

 a distance is also zero in a physical sense, so 

 that two atoms, whose loci are OT and QL, may 

 be said to be in virtual contact at any two 

 points such as O and L or and Q, which are 

 connected by singular lines. If the point O
