They were much more numerous than I had anticipated, and 

 included copies of most of those MSS. which are specified in Mr. 

 Clift's evidence before the " Medical Committee of the House of 

 Commons" (Appendix B). 



After Mr. Cliffs decease I proceeded to classify the Subjects of 

 the MSS.; to prepare ' press-copies ' of them; to determine the 

 Species of animals therein referred to, and especially of those of 

 which Hunter's ' Notes of Dissection ' were thus preserved; to 

 compare the descriptions of structures in those notes with the 

 Preparations in the Hunterian Collection, in order to refer to the 

 preparations of parts of animals which are described in the 

 Anatomical MSS., or which relate to propositions recorded in the 

 Physiological Essays. 



Where the number only of the Preparation is given, as at vol. i. 

 p. 20, or where the abbreviation " Phys. Series " is added in the 

 foot-note, it refers to the " Physiological Series of Preparations in 

 Spirits," as numbered in the " Descriptive and Illustrated Cata- 

 logue " of that series, 4to, 5 vols. 1833 — 1840. These Preparations 

 are now (1863) arranged in the galleries of the 'third' museum of 

 the Royal College of Surgeons, Lincoln's Inn Fields. Where 

 Hunterian specimens in other series are referred to, the name of 

 the series or its Catalogue is added, as ' Osteol. Series/ ' Series of 

 Monsters/ l Dry Preparations/ 'Catal. of Fossils/ &c. The numbers 

 of the Osteological specimens are those by which they are referred 

 to in my "Descriptive Catalogue of the Osteological Series," 4to, 

 2 vols. 1853 : those of the Fossil specimens, as at pp. 314, 317, vol. 

 i., are the numbers in the " Descriptive Catalogue of the Fossils," 

 4to, 3 vols. 1845, 1854, and 1856. 



Explanatory Notes have been sparingly appended. I believed 

 that the Physiologist, Anatomist, or Naturalist might prefer to 

 frame his own explanation of phenomena alluded to, and would be 

 able to make his own comparison of Hunter's views with the 

 present state of science. 



The Editor's notes are distinguished from Hunter's by being 

 placed below the line, within brackets, and by having numerals 

 prefixed instead of the usual marks of reference. Those by Mr. 

 Clift are marked by his initials W. C. The parentheses of Hunter 

 are bracketed thus ( ) ; those of the Editor thus [ ] .
