[TVARC] Morse code item

I used to manually set printing type. The letters were in a California type box. The letter quantity matched that usage.Sent from my T-Mobile 4G LTE Device

 The inventor of Morse code, Samuel Morse
(1791-1872), needed to know this so that he could give the simplest codes to
the most frequently used letters.  He did
it simply by counting the number of letters in sets of printers' type.

The figures he came up with were:


 
  
  12,000
  
  
  E
  
  
  2,500
  
  
  F
  
 
 
  
  9,000
  
  
  T
  
  
  2,000
  
  
  W, Y
  
 
 
  
  8,000
  
  
  A, I, N, O, S
  
  
  1,700
  
  
  G, P
  
 
 
  
  6,400
  
  
  H
  
  
  1,600
  
  
  B
  
 
 
  
  6,200
  
  
  R
  
  
  1,200
  
  
  V
  
 
 
  
  4,400
  
  
  D
  
  
  800
  
  
  K
  
 
 
  
  4,000
  
  
  L
  
  
  500
  
  
  Q
  
 
 
  
  3,400
  
  
  U
  
  
  400
  
  
  J, X
  
 
 
  
  3,000
  
  
  C, M
  
  
  200
  
  
  Z
  
 


 

 

However, this gives the frequency
of letters in English text, which is dominated by a relatively small number of
common words.  For word games, it is
often the frequency of letters in English vocabulary, regardless of word
frequency, which is of more interest. We did an analysis of the letters
occurring in the words listed in the main entries of the Concise Oxford
Dictionary (11th edition revised, 2004) and came up with the following
table:

 


 
  
  E
