well as suited to therequirements of optometrical practice, is presented. IjQi abc, Fig. 1, represent a prism, with the ray z incident perpendicularly to ab, and we shall have dv as the deflection accruing from the refraction at e. Similarly, d V will represent the deflection arising from the… … Fig. 1. By adopting one meter as the distance of the point e from the plane /Vj,in which the amplitudes of deflection dv and dV are measured, we shallhave </tf = 1, when dV = d,e (1) It is further evident that the greater the refractive power of the prism,the greater will be its correlative…
