Excerpt: ...A, 0 This determinant is, when worked out, (/+ g cos C) (g + h cos A) (A +/cos B) + (A + g cos A) (/+ h cos B) (g +/cos C), which breaks up identically into the product of sin A + g sin B + h sin C into gh sin A + A/sin B + _/j sin C; this result determining the locus of (/, g. A), according to what we all know, to be the circle circumscribing the original triangle. The geographical statement of this theorem homographically transformed, runs thus: Consider two fixed points joined by a line intersecting the three sides of a triangle; to each point of intersection successively let there be taken the harmonic conjugate with the fixed points as a pair of conjugates: join each point so determined with any point on the conic passing through the fixed points and the vertices of the triangle; the intersections of these connectors each with the "corresponding" side of the original triangle, lie in a straight line. And, analytically stated, the proposition is as follows; Let (a,/8, 7), (a', /8', 7') be the two fixed points, and (/, g, h) the arbitrary point on the conic circumscribing the triangle of reference. The coordinates of the "harmonic conjugates" spoken of above are as follows; viz., x: y: z = y'a. + 7o': /$ + yff: 277' for that corresponding to the point of intersection on the side x, and similar expressions for the other two. The coordinates of the point where the line joining this conjugate with the point (f, g, h) intersects the side 2, are x: y: z = h (7'a + 7o')--2/77': h (y'0 + y0')--2gyy': 0, with similar expressions for the other two points of intersection; and the condition that these three should lie in a straight line is 0, f(a'0 + a$')-2gaa', f (a'y + ay')-2haa' 1 0 03a' + iS'o)-ye/', 0, g (#7 + 0Y)-2 W-0....

As an example of the class of problems to which I refer, I would here propose for solution the following question:--"A point is taken at random on a window consisting of nine equal square panes, and through this point a line is drawn in a random direction. What are the respective chances of the line so drawn cutting one, two, three, four, or five panes?" Experimentally this may be solved as follows. Take a circular piece of white card-board; draw a straight line across the centre on one side, and through the centre on the opposite side insert a pin. Move the cardboard round this pin as a pivot till the stiffness is so far gone that when the pin is held by the point head downwards, a slight jerk of the finger will make the card-board revolve easily and rapidly. This may be a rude contrivance, but it will answer the purpose. Now draw a figure on paper representing the window; twirl the card-board, and while it is spinning mark with a pencil a point anywhere on the figure. If the rotatory motion of the card-board still continues, arrest it suddenly, so as to economize time; then place the card-board on the paper so that the pin's head shall fall on the pencil mark, or near it, extreme accuracy upon this point not being at all necessary. Observe now how many panes the line drawn across the centre of the card-board would cut through if produced; and register accordingly. Mark another point with the pencil, and proceed as before; and so on as long as you please; taking care, however, to distribute the points as ...
