In this connection it is important to call attention to the diflference Poroscopy 307 between an enlargement and a magnification, as the two words are verydifferent in meaning, although often used interchangeably. When an object is magnified, more details appear than were seenbefore, and new details continue to appear as the amount of magnificationincreases, but in an enlargement the details already there are made bigger,area for area; you get no new information, but what has been alreadypresented is larger. The face of the manager on a circus poster may besix feet across, but in it there are no more details to be seen of the textureof a face than one sees at the natural size. It is merely enlarged, for the. Figure 124. A fork, enlarged 32 diame-ters, illustrating the differences in size, shape,position,and number of pores, on two adjacentridges.

If a face were really to be -magnifiedto that size, think of the details of the skin which would appear upon it! Now if an ordinary print were to be magnified to, perhaps, 30 diame-ters, the fibers of the paper would show so distinctly that the backgroundwould look like a rough blanket; also the ink surface, with the particlesof which it is composed, would resemble sandpaper. Another decidedlyundesirable feature that would appear would be that the margins every-where, where black and white areas come together, would become irregu-lar and uncertain, and this character would increase with each power ofmagnification, until the prints would b
