TWENTY-SIXTH ANNUAL MEETING.

No. 2 is obtained by transposing adjacent columns, as the second with the 

 first and the fourth with the third. To express this change the syllable tro, with 

 the meaning of (wound, will be used. Hence, this will be called transposing by 

 trovcrsion. This puts the number 14 in the upper-left-hand corner — the key 

 corner. 



No. 3 is formed by d/viding No. 1 ve/'tically and placing the last half before 

 the first half. Mnemonically, we take the first syllables of the two expressive 

 words, as above, and call this transposing by diversion. This puts 12 in the ini- 

 tial or key corner. 



No. 4 is obtained by reversing the lines and placing 7 in the key corner. It 

 is called transposing by reversion. 



No. 5 is obtained by transposing adjacent lines of No. 1, the second with the 

 first and the fourth with the third; as the columns were transposed to foim 

 No. 2. For this, the syllable con, with the sense of over, will be used. This, 

 then, is transposing by conversion, and places 15 in the key corner. 



No. G is derived from No. 1 by converting the troverted square No. 2 or by 

 troverting the converted square No. 5. This is transposing by controversion, 

 and puts 4 in the upper left-hand corner. 



No. 7 is obtained from No. 1 by converting the diverted square No. 3, or by 

 diverting the converted square No. 5. This is called transposing by condiver- 

 sion, and brings 6 into the upper left-hand corner. 



No. 8 is obtained by reversing the lines of No. 5 or by converting No. 4. This 

 is called reconversion and brings 9 into the key corner. 



No. 9. 

 By Subversion. 



No. 10 

 By SuhtrovcTsion. 



No. 12. 

 By Resubversion.
