FUNCTIONS OF MOTOR AND SENSORY NERVES 91 



(5) 1826. On the nervous circle which connects the voluntary Muscles 



with the Brain. By Charles Bell, Esq. Communicated 

 by the President, January 25, 1826. — Read February 

 16, 1826.— Phil. Trans. R.S. 1826, Part II. p. 163. 



(6) 1829. On the Nerves of the Face ; being a second paper on that 



Subject. By Charles Bell, Esq. F.R.S.— Read May 

 28, 1829. — Phil. Trans. R.S. 1829, p. 317. 



Besides these six papers, Bell published three general 

 accounts of the Nervous System in 1824, 1830 and 1836, which 

 are, in fact, three successive editions of the same work, although 

 the first edition was published under a different title ; the 

 "third" edition was printed twice — in 1836 during Bell's life, 

 and in 1844 after his death. 



These three editions are : 



In 1824. First. — An exposition of the natural system of the 

 Nerves of the Human Body. With a republication of the papers 

 delivered to the Royal Society on the subject of the Nerves, by 

 Charles Bell, Professor of Anatomy and Surgery to the Royal 

 College of Surgeons ; Teacher of Anatomy in the School of 

 Great Windmill Street ; and Surgeon to the Middlesex Hospital. 

 8vo, London. Printed by Eyre & Spottiswoode, 1824. 



In this volume the Introduction of sixty-six pages belongs 

 to the year 1824. The paper "On the Nerves," etc., from the 

 Philosophical Transactions of 182 1, occupying pp. 67 to 180, 

 contains many alterations from the original version, none of 

 which are acknowledged or even hinted at. 



This is the most important of the three editions ; it shows 

 as clearly as possible the transformation of Bell's views on the 

 fifth nerve caused by the publications made by Magendie in the 

 Journal de Physiologic of 1822 and 1823. 



In 1830. Second. — The Nervous System of the Human Body ; 

 embracing the papers delivered to the Royal Society on the subject of 

 the Nerves, by Charles Bell, F.R.S., 4to, London, 1830. Published 

 by Longman, Rees, Orme, Brown & Green, Paternoster Row ; 

 and J. Taylor, Upper Gower Street. 



Dedicated to the King, with a preface of thirteen pages and 

 a note for which Bell " is indebted to a pupil " {i.e. Alexander 

 Shaw) asserting the claim of Bell against Magendie. The 

 Phil. Trans, papers of 1821, 1822, 1823 (2), 1826 and 1829 

 are reprinted with further modifications. The paper of 1829 

 — which consists substantially of a repetition of those of
