| Fluid removed after 1st 10 minutes following injection | 4.0 c.c. |
| Fluid removed after 2d 10 minutes following injection | 3.4 c.c. |
| Fluid removed after 3d 10 minutes following injection | 3.0 c.c. |
In this rabbit the increased secretion of fluid was accompanied by extremely active peristaltic movements. The faeces could be seen passing along the loops of the lower part of the intestine with great rapidity. Within 30 minutes after the administration of the salt, the passage of faeces to the outside began. This continued for some time, the faeces becoming constantly softer, until finally they were almost entirely unformed.
As shown by this experiment, and also by the following ones, the action of barium chloride persists for a considerable length of time. The action of sodium citrate is more transitory.
