Figure 13. Overall body insulation (•) expressed as the slope of the tempera- 

 ture-metabolism curve below the thermoneutral range ( C/calA)ody weight 3/4 /hr) 

 in relation to body weight, and slope (O) as a function of pelage insulation (brokeni 

 line). Data are replotted from table given by Hart 1962b.
