The Publisher would can the attention of the Trade to the above very valuable Medical Book now first 

 reprinted from the English Translation of the Third German Edition 



The above Lectures were delivered in the year 18!i8,in the new Pathological Institute of the University of 

 Berlin, in the presence of a large number of the first Medical Men in that city. 



The importance of the subject, the new ideas advanced, and the well-known reputation of the Lecturer, 

 compelled the publication of these Lectures in Book form, and it is now considered the Standard Work 

 throughout Germany, on this subject. We would herewith submit the translator's Preface : 



" Professor Virchow and his works are so well known wherever the science of Medicine is studied, that 

 I think it quite unnecessary to give any account of them here. 



" When I arrived in Berlin, in March, 1858, these Lectures were in the course of delivery, and I was 

 present at a few of the concluding ones. Subsequently, whilst attending the lectures, classes, and post- 

 mortem examinations {from 700 to 8PO bodies .are examined annually in the Institute) which are held in the 

 Pathological Institute, by Professor Virchow, I had ample opportunities for seeing practical illustrations of 

 most of the doctrines advocated in this book. It was natural, therefore, that I should feel a desire to trans- 

 late these lectures, the more especially as I had every reason to suppose that the views put forward in them 

 still remained unknown in consequence, no doubt, of their German dress to a large proportion of the 

 Engl^h Medical Public, although they had already, many of them several years previously, appeared in Pro- 

 fessor Virchow's larger works. 



" The translation will in many instances be found to differ somewhat from the original, for numerous 

 additions, subtractions and substitutions have beea made, many of them at the suggestions of the author, 

 many at my own, but all with the author's sanction. 



"A few Notes will be fouud, especially in the latter Lectures. Of these some are literal, some free 

 translations of, or are based upon answers I received from Professor Virchow to 'questions I had put to 

 him, whileothers were trade entirely at his own suggestion, and are literal translations of his words. In all 

 cases, however, the Notes have been submitted to the author, and approved by him. 



" An Index too, I thought might be of service, and I have therefore added a tolerably full one. 



" I cannot sufficiently thank Professor Virchow for the very great trouble a trouble of which nobody 

 but myself can have any idea which he has taken in revising this translation, nor for the courtesy and 

 kindness with which lie has replied to tho very numerous questions many of them put for my o wn private 

 information which I have plagued him with. He has written me fully fifty letters, most of them very long 

 ones ; and when I reflect that he daily pusses eight or nine hours at the Charity, that he reads all the more 

 important German, French and English Medical Works which appear, and is besides constantly engaged in 

 publishing something fresh, I can scarcely conceive how he has managed-to find time to write these letters, 

 of which a large proportion reached me by return of post. 



In its publication no expense has been spare 1 . In typography, paper or illustrations ai now issued, it 

 contains nearly 800 pages, Royal Octavo, handsomely bound in cloth, witi beveled boards, an 1 retailed at 

 $5 per copy. 



f&~ Copies of the above book will be sent postage paid, on receir t of price. Address,
