has been as uniformly followed by improvement without the aid of 

 medicine. It is a true maxim in physic that diseases which are long 

 in their advancement are, as a rule, only to be remedied by long-con- 

 tinued curative attention. Common-sense proves the fallacy of expect- 

 ing to eradicate old-established errors of the body by any sudden 

 remedies ; the diet and medical regimen of such persons should there- 

 fore be undeviatingly suited to their disordered tendencies, and reso- 

 lutely maintained as long as they afford any hope of relief. 



We have seen that certain foods, such as the fats themselves, and 

 others that consist principally of starch or sugar, favor the develop- 

 ment of corpulence ; and it will be observed that in the following die- 

 tary designed by Dr. Harvey, and prescribed by him in the famous 

 case of Banting, foods of this class are reduced to a minimum, though 

 not altogether interdicted, the nitrogenous foods being correspondingly 

 increased. 



Breakfast. Four to six ounces of meat, two ounces of biscuit or 

 toast, and a large cup of tea, but without milk or sugar. 



Dinner. Ten to twelve ounces of any fish except salmon; any 

 vegetable except potatoes and vegetable roots ; any kind of poultry or 

 venison, and two ounces of toasted bread. With it drink two or three 

 glasses of good red wine, sherry or madeira, avoiding champagne, 

 port, or beer. 



In the afternoon, four to six ounces of fruit, one or two biscuits, 

 and again a large cup of tea without milk or sugar. 



Supper. Six to eight ounces of meat or fish, and one or two 

 glasses of red wine. 



Dr. Harvey remarks : " When once the body has reached its full 

 development in manhood, the quantity and quality of the food should 

 be regulated by the demand made by the wear and tear of the system. 

 If, for instance, a person, already sufficiently stout, is growing fatter 

 and fatter, he is taking more fattening food than is necessary or safe, 

 and must restrict himself if he would restore the balance of the func- 

 tions."

THE STUDY OF PHYSICAL SCIENCE. 



A LEOTUKE TO YOUNG MEN". 



By Ekv. CHAELES KINGSLEY. 



SOME of you may ask, and you have a perfect right to ask, why I, 

 a clergyman, have chosen this subject for my lecture ? Why do 

 I wish to teach young men physical science ? What good will the 

 right understanding of astronomy or of chemistry, or of the stones 

 under their feet, or of the plants or animals which they meet What 

 good, I say, will that do them ? -
