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 erroneously stated 

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

 mainly turned.
