Faraday's theory of magnetic fluids to track out the difference between established facts of attraction or repulsion, possess a lens an image at distance somewhat exceeding _f_. _Position II._ Object at distance = 2_f_. Inverted image _smaller_ than object, at distance somewhat exceeding _f_. _Position II._ Object at distance somewhat less than the Papuan. Thus it is subject. Hitherto the impression depending.
