Mathematical recreations and essays . e angles of the two side crosses of Snuffer-Trayswhich lie towards Qs hands, both thumbs being towards Qs left P takes hold of each cross with the thumbs and fingers and pulls itdownwards, then he separates his hands thus bringing each cross below itscorresponding horizontal string, and continuing the motion he passes the crossoutside, round, and then above the horizontal string. Third. P turns eachthumb and finger inwards { towards the centre of the figure) between the twohorizontal strings through two right angles taking the horizontal strings withthem. Lastly. P pushes his fingers down, separates the index-fingers from thethumbs, and then, drawing his hands apart, removes the figure from Qs hands. The figure now is in a horizontal plane; but for clearness I have drawn itas seen by Q, when P lifts his hands up. Fish-in-a-Dish—see figure iv—is composed of a centrallozenge (the dish) on which rest lengthwise two strings (thefish). There are two loops on each Figure iv. Fish-in-a-Dish B. R. 23 354 STRING FIGURES [CH. XVIII Fish-in-a-Dish is produced from Cats-Eye thus. I suppose that Cats-Eyeis held by P in the normal position, his fingers pointing down, and the figurelying in a horizontal plane. First. Q puts the thumb and index-finger of eachhand from above into those angles of the two side crosses which he towardsPs hands, both thumbs being towards Ps right hand. Second. Q turns eachhand inwards ( towards the centre of the figure) through two right angles,and as he does so, catches the sides of the central diamond on the thumb andindex-fingers. At the end of the motion the thumbs and fingers will bepointing upwards. Lastly. Q draws his hands apart and thus takes thefigure off Ps hands. The diagram represents the figure as seen by Q. The same result is produced if Q inserts his thumbs and index-fingers frombelow into the two side crosses, and turns his hands inwards through two rightangles. There
