Vlll PREFACE. 



Albuminuria, the printed slips of Dr. Sheridan Lea, Gruen- 

 hagen's Lehrbuch der Physiologie, Helmholtz's Physiologische Optik, 

 Krukenberg's Grundriss der Medicinisch-Chemischen Analyse, and 

 Hoppe-Seyler's Handbuch der chemischen Analyse. 



One feature valuable in any Text-book designed for practical 

 ends, viz., the keeping in view of the fact that " the Student of 

 to-day becomes the Practitioner of to-morrow," has been con- 

 stantly before me. Hence, the aim has been so to arrange 

 the exercises as to give them a bearing on, and to lead gradually 

 up to, the methods used in Practical Medicine. 



I am indebted to Mr. John T. Millett, B.Sc., and to my 

 demonstrator, Mr. A. F. S. Kent, B.A., for reading the proof- 

 sheets. 



Many of the illustrations were drawn for me by my pupil, Mr. 

 Philip Worley, and some were photographed from apparatus in 

 the Physiological Laboratory of The Owens College, by Mr. 

 William Charles, Steward of this department. I have also to 

 express my thanks to several scientific instrument-makers, 

 including Messrs. Browning, Elliott, Maw Son & Thompson, 

 Jung of Heidelberg, Rothe of Prague, and Carl Reichert of 

 Vienna. Some of the illustrations are from the Text-Rook of 

 Physiology by Landois and Stirling.
