 aXiere. '—Montada. 



'In the Optical Lectures many problems connected with the reflexion and refraction of light are treated with 

 ingenuity. The geometrical focus of a point seen by reflexion or refraction is defined ; and it is explained that the image 

 of an object is the locus of the geometrical foci of every point on it. Barrow also worked out a few of the easier 

 properties of thin lenses; and con.siderably simplified the Cartesian explanation of the rainbow. The geometrical 

 lectures contain some r.ew ways of determining the areas and tangents of curves. The most celebrated of these is the 

 method given for the determination of tangents to curves'.— IF. W. R. Ball.
