[Image unavailable.] 164 DESCRIBE CIRCUMFERENCES AS INDICATED, AND TAKE THE DIAGONALS OF SIX IN SIX DIVISIONS. DRAW A HORIZONTAL LINE AT THE HIGHER LINE OF THE LITTLE PENTAGON, AND REPEAT THE CONSTRUCTION BELOW THE LINE. [Image unavailable.] 165 DIVIDE CIRCUMFERENCES AND DRAW PARALLEL LINES AS INDICATED. TAKE THE DIAGONALS OF SIX IN SIX DIVISIONS, AND THE REST FOLLOWS. [Image unavailable.] 166 DESCRIBE CIRCUMFERENCES EQUAL AND TANGENT, AND TAKE THE DIAGONALS OF FOUR IN FOUR DIVISIONS; THEN IN THE CONCENTRIC CIRCUMFERENCES TAKE THE DIAGONALS OF SIX IN SIX DIVISIONS. [Image unavailable.] 167 SUB-DIVIDE AS IN PLAN. INSCRIBE THE ROSETTE OF TEN POINTS; THE LITTLE PENTAGONS AND LOZENGES FOLLOW, AND THE REST FOLLOWS. [Image unavailable.] 168 ANALOGOUS TO NUMBER 167, BUT IN PLACE OF THE ROSETTE STARS ARE FORMED. [Image unavailable.] 169 CURVILINEAR TRANSFORMATION OF NUMBERS 167 AND 168. THE POINTS OF CENTRAL DISTRIBUTION ARE MARKED BY MINUTE CROSSES. [Image unavailable.] 170 SIMILAR GROUND WORK TO THE THREE FOREGOING DIAGRAMS. THE LITTLE PENTAGONS GOVERN THE DESIGN. [Image unavailable.] 171 DESCRIBE THE CIRCUMFERENCES AS IN PLAN, AND INSCRIBE THE DECAGONAL STAR. THE SMALL DECAGONS IN THE CENTRE OF THE TRIANGLES OF THE PLAN, BY EXTENDED LINES, FORM THE ROSETTE. [Image unavailable.] 172 DIVIDE AS IN PLAN. UPON THE LESSER SIDE TRACE AN ISOCELES TRIANGLE. BY THE APEX OF THE TRIANGLE TRACE A CIRCUMFERENCE, IN WHICH TAKE THE DIAGONALS OF THREE IN THREE DIVISIONS. [Image unavailable.] 173 LOZENGE PLAN, WITH COMBINING LINES. THE LOZENGE IS IMAGINARY, AND DOES NOT INDICATE THE RADII IN EXTENSION ONE WITH THE OTHER, BUT ONLY THE ORDER OF SUB-DIVISION OF THE PENTAGONAL AND DECAGONAL ROSETTES. [Image unavailable.] 174 SUB-DIVIDE AS IN PLAN THE SPACE SURROUNDING A POINT INTO TWENTY EQUAL PARTS. AT THE MEETING OF THE HORIZONTAL WITH THE VERTICAL LINE DRAW A CONCENTRIC CIRCUMFERENCE IN WHICH IS INSCRIBED THE STARRED DECAGONAL ROSETTE. THE SMALL PENTAGON IS DOMINANT. [Image unavailable.] 174 SAME GROUND-WORK AS NUMBER 172, BUT WITH A GREATER INTERVAL BETWEEN THE ROSETTES. ONE OF THE ROSETTES, INSTEAD OF BEING RECTILINEAR, IS CURVILINEAR. [Image unavailable.] 175 SUB-DIVIDE AS INDICATED. DESCRIBE CIRCUMFERENCES EQUAL AND TANGENT, AND TAKE THE DIAGONALS OF FOUR IN FOUR DIVISIONS. LASTLY, THE ROSETTES ARE EFFECTED. [Image unavailable.] 175’ DRAW CIRCUMFERENCES AND SUB-DIVIDE AS IN PLAN. TAKE THE DIAGONALS OF FOUR IN FOUR DIVISIONS, WHICH, PROLONGED, COMPLETE THE DESIGN. [Image unavailable.] 176 DESCRIBE CIRCUMFERENCES AND TAKE A PERPENDICULAR LINE TO THE BORDER OF THE RADIUS; TAKE THE DIAGONALS OF FOUR IN FOUR DIVISIONS, WHICH PROLONGED, COMPLETE THE FIGURE. [Image unavailable.] 176’ RECTANGLE PLAN OF DIAGONAL SYMMETRY. TAKE THE DIAGONALS OF FOUR IN FOUR DIVISIONS. THEN BY A CONCENTRIC CIRCUMFERENCE. SET OUT THE ROSETTE. THERE ARE, IN FACT, THREE ROSETTES OF TEN POINTS EQUAL AND TANGENT. [Image unavailable.] 177 LOZENGE PLAN, WITH COMBINING LINES A CONCENTRIC CIRCUMFERENCE DESCRIBES A STAR THE ROSETTE IS THEN DRAWN. THEN GRADUALLY, BY THE AID OF THE PENTAGONAL ADJUSTMENT, THE NET-WORK IS DESCRIBED. [Image unavailable.] 178 LOZENGE PLAN, WHERE THE GREAT AXIS IS THREE TIMES THAT OF THE LESSER AXIS. SUB-DIVIDE AS IN PLAN. TRACE CIRCUMFERENCES EQUAL AND TANGENT, IN WHICH ARE INSCRIBED REGULAR PENTAGONS. THE REST IS EASILY FOLLOWED. THE NET-WORK IS COMPOSED OF FIVE SERIES OF LINES.
