PREFACE. 



THIS Work is intended as a Manual for Medical 

 Students. The original plan was to embody in it 

 only such matter as was absolutely required for the 

 first year's student in the Medical Schools ; but this 

 plan was not carried out, since the book would then 

 have been, in some measure, incomplete as a Manual 

 of Histology. The work contains a good deal that 

 will be acceptable to the advanced student, as well 

 as to the beginner. 



My best thanks are due to Mr. Charles Berjeau, 

 F.L.S., for the readiness and artistic skill with which 

 he has executed the illustrations on wood. Some of the 

 figures are reproduced from my " Atlas of Histology," 

 others from the "Handbook for the Physiological 

 Laboratory." The former are marked "Atlas," the 

 latter " Handbook."
