1 82 1 and 1822 plus the information gathered by Bell from the 

 publications of Magendie and of Mayo — is interpolated between 

 them. The order of the papers as given in this republication is 

 1821, 1829, 1822, 1823 (2), 1826. 



The first part of the introduction (pp. 1 to 13) is new. The 

 second part of the introduction (pp. 14 to 21) is substantially as in 

 1824; a footnote at p. 14 says that it was " written as introduc- 

 tory to the first edition." This footnote thus fixes what is 

 otherwise left vague, that by first edition Bell means 1824 and 

 by second edition he means 1830. (" Third edition " is prefixed 

 to the publication of 1836 and to that of 1844.)

A note precedes the preface of this edition to the following 

 effect : 



"These papers, read in succession, and at intervals according 

 as the author, engaged in an arduous profession, could find time 

 for the prosecution of such subjects, present a series which 

 requires little comment. The evidence of originality is open to 

 every unprejudiced mind. The author has neither been turned 

 aside nor hurried into premature conclusions. The principle 

 which directed him in these inquiries is stated in the very 

 beginning, and step by step the reader may follow the obser- 

 vations and dissections by which the System has been made 

 out." 



The Appendix — pp. 243-451 — containing Consultations and 

 Cases illustrative of the facts announced in the preceding papers is 

 the same in the two third editions of 1836 and 1844. The last 

 ten pages are occupied by an expansion of the historical note
