During the course of passing the tube it must be well 

 lubricated. 



When the stomach is reached the gas may have already 

 escaped and fluid contents may be siphoned off by filling the 

 tube with warm water from a funnel or syringe, holding the 

 distal end tightly closed and lowering it to the ground so as 

 to permit of the escape of stomach contents by siphonage. 

 If the contents are largely solid, the stomach must be 

 repeatedly filled with 2 to 4 quarts of warm water and 

 allowed to escape again by lowering the outer end of the 

 tube to the ground. If the flow stops, owing to choking of 

 the tube, it may be started again by injection of water into 

 the tube with a syringe or pump. 



The latter must not be used to suck out the contents of 

 the stomach except so far, if necessary, as to start the 

 siphonage. The stomach should thus be repeatedly washed 

 until the water comes away clear. If water is injected with 

 a syringe, care must be take a to avoid forcing air into the 

 stomach. 



When passage of the tube becomes impossible through 

 one nostril, the other one may be tried. Phillips reports 

 failure to pass the tube in the horse in only 5 per cent, of 

 trials. The tube is best made of red Para rubber and long 

 enough to reach from the stomach to the ground when in 

 place. 



Serum Therapy.* 



Antitoxic Serum. — The microscopic parasites which ■ 

 cause infectious diseases — of which the bacteria are the 

 most common — do so chiefly through the production of cer- 



* In the use of serum therapy the strictest aseptic precautions are 

 to be used. The animal is prepared by shaving off the hair from the 

 part and the skin is washed with soap and water and then with alcohol 

 and water, 2 parts of the former and 1 part of the latter, or with 5 per 

 cent, carbolic acid watery solution, which is harder on the hands. The 

 syringe and needle must be boiled for five minutes before using. When 

 many animals are injected at one time, it may be sufficient to wipe off 

 the needle after each injection with the alcohol solution. The puncture 

 may be covered with collodion to advantage. Glass syringes, with 

 asbestos packing on plunger, are most suitable for boiling, the needle 

 connected by rubber tubing.
