GENERAL OBSERVATIONS. 



They are all whole numbers, or terminate in 0-5 

 or 0*75 they never terminate in O&5. 



5 are multiples of 8 atoms of hydrogen. 

 1 is a multiple of 4 

 3 are multiples of 2 



5. The atomic weights of the intermediate

These, like the former set, are either whole 

 numbers, or they end in O5 or 0*75, and never 

 in 0-25.
