iv. Preface. 



not neglect to cnltivate tliat portion of pliysicat science icJiicJi 

 is tlie iionuiin of tlie p/iysiologist — tJie physics of living 

 matter. 



Davy, by his close physiological stndv of nitrons oxide, 

 pointed out the ivay toivards the establisJinient of Ancvsthesia. 

 Faraday took part in tlie foundation of onr knou'ledge of 

 Animal Electricity by his physiological investigation of the 

 electric eel. It is indeed throngJi its Fnllerian Professors 

 of Chemistry rather than through its Fnllerian Professors 

 of Physiology, that the Royal Institntion has fnrtJiered onr 

 knoivledge of living matter. 



No clearer proof conld well be offered of the absolute 

 dependence of any branch of Science upon its laboratories 

 rather than upon its lecture-theatre. The Fnllerian professor- 

 ship of Chemistry has been fruitful, not only in its vivu 

 department, but also in the allied department of Physiology. 

 The Fnllerian professorship of Physiology has been com- 

 paratively sterile, even ivithin its own nominal province. 

 Both chairs have been held by men of the highest distinction ; 

 bid the former has rested upon a laboratory, while the 

 latter — so far from resting upon a laboratory — does not 

 possess even one small room in ivhich to keep itself alive.
