Mr. W. W. Rouse Ball 



[March 12, 



paragraph.] Examples of this have been found in Africa, Oceania 

 and America, but it was said to be unknown in Europe. This he 

 had learnt here in boyhood, and therefore supposed it to be an 

 English production. On enquiry we found that his nurse had taught 

 it to him, and as a result of further talk it seemed that she had got 

 it from a sailor to whom she had been engaged to be married ; the 

 conclusion that the latter had learnt it in the course of his voyages

seemed a safe one. The figure in question is typical of the numerous 

 patterns made of diamond-shaped lozenges, strung between two parallel 

 strings, arranged either in single rows (of one or two or more, as the 

 case may be), or in the form of rows side by side as in Fig. 2. 



\_A Fishing Net. — The successive movements which produced the 

 result shown in the Lecture may be put in the form of the following 

 rules -.—First : Take up the string in the form of Opening A.* Second : 

 Release the thumbs, then bend them away from you under four strings, 

 and with their backs pick up the far little-finger string, and return. 

 Third: Bend each thumb away from you over one string, and with 

 its back pick up the next string- Fourth : Release the little-fingers, 

 then bend each of them towards you over one string, and with its 

 back pick up the next string. Fifth .- Release the thumbs, then 

 bend each of them away from you over two strings, and with its 

 back pick up the next string. Sixth : Pick up from the base of 

 each index-finger the near index string, and put it over the corre- 

 sponding thumb, and Xavaho'" the thumb loops. Seventh .• Put 

 each index-finger from above into the adjacent palmar triangle, 

 whose sides are formed by the radial little-finger (palmar) string 

 twisting round the thumb loops. Lasitij .- Rotate the right hand 

 counter-clockwise and the left hand clockwise (in doing which the 

 little-finger loops and the proximal index loops will fall off, the 

 palms of the hands will face outwards and away from you, the 

 thumbs will be below the palms and point away from you, and 

 ili»' index-fingers will point upwards), and separate the hands.] 



This term is explained below, on page 93.
