 latter. The above work was unknown to the author's biographer in D. N. B. 



7011 Part I : Reply to Mr. Wheatstone's Answer, 8vo. cl., 65 Qd 1856

The first patent includes the five-needle apparatus, which was shortly afterwards given up as impracticable. The 

 second is that of the two-needle apparatus, patented by Cooke alone (not jointly with Wheatstone, as eri-oneously stated 

 in D. N. B.), which formed the basis of the single needle apparatus, on which his controversy with Sir Charles Wheatstone 

 mainly turned.
