 left to this laborator}- for use as long- as their research of this type 

 is continued. With the apparatus available, this is at present the 

 best and most efficientl}- equipped laboratory in existence to carry 

 out research in metabolism of farm livestock. 



Much of this modernization of apparatus and of technique has fol- 

 lowed principles successfully applied to studies of energetics in re- 

 lation to human physiology by the Nutrition Laboratory of the Car- 

 negie Institution of Washington (see Xew Hampshire bulletin Xo.

IM.ACII) TVFl-: ACTIVE TYPE 



}'U;iRE 7. SEAT OF THE VITAL ORGANS 



An index of the comparative adaptation of contrasting functional types to use energy. The 

 active tvpe has a iari<er motor (ie.. vital organs) in proportion to its size. It uses up more 



fuel. The placid type stores more. 



That this contribution to research in animal nutrition represents 

 a verv significant advance in both method and result is indicated by 

 the scientific interest manifested in its progress and results. 



Since our first results have been published our laboratory has 

 been honored by 170 visitors interested in nutritional physiology and 

 in applied practical nutrition. This number includes 39 scientists 

 representing 17 dift'erent countries in Europe. Asia, Africa, South 

 America and Australia. 



A further example of this may be cited in the public interest shown 

 in an exhibit prepared by this laboratory portraying in summary the 

 conclusions and the fimclamental ]>hysiolog-ical signifiance of our com- 

 parative studies in metabolism. This exhibit was originally prepar-
