**subtended**by a pair of large bracts. - We conclude that a double line cannot be fairly resolved unless its components subtend an angle exceeding that
**subtended**by the wave-length of light at a distance equal to the horizontal aperture. - If the angle

**subtended**by AP is E/D, and the angular resolving power is given by X/2 D sin a = X/2 R (3) This method of derivation (substantially due to Helmholtz) makes it obvious that there is no essential difference of principle between the two cases, although the results are conveniently stated in different forms. In the case of the telescope we have to deal with a linear measure of aperture and an angular limit of resolution, whereas in the case of the microscope the limit of resolution is linear, and it is expressed in terms of angular aperture. - The ratio between the limiting angles
