n the tone of the stomach is defective the retainedfood sinks to the lower part and there is nothing, except theway in which the food drops to the lowest part (see Fig. 28),to indicate its presence. The picture is simply thatof an atonic stomach in which peristalsis is more violent thanone would expect in a thinned-out organ. Retention of bismuth food is the result of pyloric obstruc-tion and Rieder laid it down that the whole of a bismuth mealshould have left the stomach within five hours. As hasalready been pointed out (pp. 50, et seq.) this is toosweeping a generalization, but, with the reservations stated,it is sufficiently accurate. The question of the rate of empty-ing is, however, discussed on p. 50, but one must againcall attention to the fact that in the early stages of pyloricobstruction there may be not only no delay but actually morerapid emptying than usual (as in Case 126)—the result ofoveraction of compensation. Bad teeth and septic conditions of the mouth, etc., must

A little food has just been given, and is seen extendingfrom the cardiac orifice to the mass of food in the lowest part. Notehow this is held up to some extent in the upper part by the walls ofthe stomach being in apposition.

Radiogram of Type 2 of pyloric obstruction. The platewas taken 24 hours after the bismuth food had been given and noneof the food seems to have left the stomach. Note the perfect tonicaction, the absence of peristalsis, the wide column of fluid above thebismuth shadow and the fluid line forming the lower margin of theair-space.
