APPENDIX. 



icy," &c. You write with twelve letters only, as in the subjoined 

 table, in which however I have not followed his ways of diver- 

 sifying. 



In this table, z 1? for instance, represents 1st M, and 2nd R or S ; 

 to distinguish whether R or S, he has recourse to a supplementary 

 contrivance by nulls. 



f. 242. v. He refers to table at 200., and says the three letters a b c, 

 (which there represent I ) may be replaced by a single character ; 

 for this table represents in another column letters by dots. Thus 



T is ; D ; or if we will we may put o's for dots ; so that 



D=o o o and T=oo ooo o ; and the spaces may be filled up by a 

 slightly varied o. Thus D =00000, T =00000000, and thus the 

 whole cipher will apparently consist of o's. 



The transition from this to Bacon's cipher is so easy that the 

 credit given to him must be reduced.
