MICROGRAPHY AND MICROPHOTOGRAPHY 141 



Lord's Prayer has been written and may be read in the 

 one-three hundred and fifty-six thousandth of an English 

 square inch. The measurements of one of these specimens 

 was verified by Dr. Bowerbank, with a difference of not 

 more than one five-millionth of an inch, and that difference, 

 small as it is, arose from his not including the prolongation 

 of the letter/ in the sentence 'deliver us from evil ' ; so 

 he made the area occupied by the writing less than that 

 stated above." 



Some idea of the minuteness of the characters in these 

 specimens may be obtained from the statement that the 

 whole Bible and Testament, in writing of the same size, 

 might be placed twenty-two times on the surface of a square 

 inch. The grounds for this startlir^ assertion are as 

 follows : " The Bible and Testament together, in the English 

 language, are said to contain 3,566,480 letters. The num- 

 ber of letters in the Lord's Prayer, as written, ending in 

 the sentence, 'deliver us from evil,' is 223, whence, as 

 3,566,480 divided by 223, is equal to 15,922, it appears 

 that the Bible and Testament together contain the same 

 number of letters as the Lord's Prayer written 16,000 

 times ; if then the prayer were written in I -16,000 of an 

 inch, the Bible and Testament in writing of the same size 

 would be contained by one square inch ; but as i-356,oooth 

 of an inch is one twenty-secondth part of 1-15,922 of an 

 inch, it follows that the Bible and Testament, in writing of 

 that size, would occupy less space than one twenty-secondth 

 of a square inch." 



It only now remains to be seen that, minute as are the 

 letters written by this machine, they are characterized by a 

 clearness and precision of form which proves that the mov- 

 ing parts of the machine, while possessing the utmost
