...i, p. 207. 2 It is well known that some chemists agree with Sir William Crookes in thinking that " probably our atomic weights merely represent a mean value around which the actual atomic weights of these atoms vary within certain narrow limits," reminding us of Newton's 'old worn particles,' But... | |
