ex-plain how the perspira-tory glands of the skinare so arranged as toallow the greatest possi-ble size in the smallestamount of space. Whyare both size and econ-omy of room necessaryhere? Find a gland whichhas more than one kindof work to do. Howdoes the structure of theliver fit it to act as anorgan of secretion, as astorehouse for any excessof sugar that there maybe in the body, and as anorgan first 6f assimilationand then of excretion? Find other organs ofsecretion which mustact as excretory organsas well. How does the way in which each ismade fit it for this double work?

If itis a part of the work ofthe liver to store upsugar, why is it not agood thing to eat muchcandy ? Why is it betterto eat oatmeal withoutsugar ? Other organs of secre-tion, such as the glandsof the skin, the eye, andear, and the membraneswhich surround bone andmuscle, and line the airpassages, work in differ-ent ways, so need differ-ent kinds of care.
