Transformation of the Stereo'/raphic Ei/natorial Projection of a sphere hy means of a certain form of the I'eancellier Cell, jhj Professor A. AV. Phillips. Tbeniacliino is made of Lavs of niotal. A is a fixed point, B traces the original ]irqji'clii)n, and C tiie new pvojection. If tile })oint A is fixed on tlie erjnator in the S'tereof/raj/hic Eqiiaforial Projection, luid W traces the meridians and paraUcls of tliis projeclion, then V, will trace tin? meridians and ])arallel3 of the Sti'rvofjrapJtic Meridian, Projection. {The proi)()rlioiis of the machine are made such that the projections of one half of the sphere in tl-e two pictures are contained in circles of the same size.). ( Al.\( HIXE. If the point A is fixed on the parallel of 6° .sonth of the equator in tin; original projection, and V> traces the parallels and meridians as hefore, tiien (J will trace the parallels and irteridihiis of the Stvrco(jraphic Horizontal Projection, in whicli the North Pole will he 5° from the Northern horizon. The ahove propositions are proved hy transforming the equations of the parallels and meridians in the original projection hy means of the relation hetween /) and p' with respect to the fixed pomt A. Tlie transformed equations agree with the expiations of these lines in the Meridian and Horizontal projections. PI A Geometrical Theorem in comiection n-ith the Three-cusped Ilyjwcijcluld, Pij R. ¥.
