EXAMINATION OF THE DIGESTIVE APPARATUS

pump. This has been recommended by Frick, and only for therapeutic 

 purposes. 



The stomach-pump is operated in the following manner: In large 

 dogs an ordinary horse catheter is used and in small dogs a large male 

 human catheter or a small rubber hose. We pass the catheter, as de- 

 scribed in the examination of the cesophagus, into the stomach and to the 

 free end of the catheter or rubber hose, which' should be about 30 cm. 

 long, we put a small funnel at the other end of the tube (Fig. 10). Pour 

 a certain amount of water into the stomach through the tube, at the 

 same time holding the tube high, and then manipulate the region of the 

 stomach and next depress the tube, and the siphon which has been formed 

 will soon empty the stomach of its contents. This method is to be used

in very urgent cases where poison is suspected, but as a rule is very hard 

 to do except in very quiet animals and where there is a trained assistant, 

 such as in a hospital; but in private practice the easier wa}- is the better, 

 that is, to administer an emetic. The best means is to give a dose of 

 apomorphia hypodermatically.

Sig. — Ten to twenty drops hypodermatically. 



In a few minutes free vomiting occurs and the contents of the stomach 

 can then be examined. Of course, you must take into consideration 

 the time which has elapsed since the animal has taken the food and the 

 character of the alimentary matter. It would be well, therefore, that 

 you know the following facts concerning (Fig. 11) digestion in the dog's 

 stomach:
