Judged by ordinary standards a fog particle, which Dr. Owens says is rarelv bigger than l-20,000tii of an inch and sometimes as email as l-100,00Oth of an inch, is incredibly small. But compared with the electron, which has displaced the atom as the smallest particle of matter, the droplets which produco fog are enormous. The most reliable estimate of the size of an electron makes its diameter one-millionth of a micro* illimetre, or 1-25.000,000-Opo,oooth of an inch. Placed side by side one line of. this column could accommodate quite comfortably 75 billion electrons, or ti-jj 000,000 would only occupy tne same space as one of the smallest' of Dr. Owen's fog particles. And when physicists discover how to harness to our needs the energy of the electron, we shall have at our command a surce of power vast beyond AMATEUR PHOTOGRAPHERS. DEVELOPING »nd PRINTING by POST.
