.80 DISEASES OF THE DIGESTIVE APPARATUS. 



symptoms in dogs infected with taenia cucumerina. In rare in- 

 stances the teeniffi have been known to penetrate the intestine. Ac- 

 cording to Cadeac, the perforation was made by two of the taeniae 

 serrata. In a great number of instances it is impossible to say 

 positively that the animal has tapeworm unless the segments are 

 ■observed in the feces, and the most dangerous to man (the tseniae 

 echinococcus) is extremely hard to find on account of the small 

 size of the segments. Other tapeworms are comparatively easy to 

 find, as the segments are readily seen on the outside of the stools 

 or catch in the anus and hang out, the dog drawing attention to 

 them by licking the anus or drawing the hind extremities along 

 the floor. In doubtful cases give a small dose of some ttenaifuge, 

 and the animal will generally pass a few segments. 



Therapeutics. The most important of the numerous tseni- 

 fuges recommended are as follows: 



1. Extract of Male Fern {extractum filix mas), is the best agent 

 to use. Should be given on an empty stomach in the morning, 

 in doses of from 1 to 4 grammes in pill-form or in capsules. As 

 this drug has no purgative properties it must be followed three 

 hours afterward by castor oil (30 to 50 grammes). It must be 

 borne- in mind that male fern in large dose is a poison, and the 

 maximum (4 gms.) must not be exceeded in the largest dog. A 

 particularly useful combination for both teania and ascarides is 



R. — 01. Ris. Mas. . 0.50 



01. Terebinthinae 0.50 



Capsule Gelatinl. — No. 1. 



Sig.: One daily for three days. 



2. Kamala. In doses of 2 to 8 gms., mixed with honey or syrup. 

 It must be repeated in one hour after the first dose, as it has purga- 

 tive properties, and it is not necessary to follow it up with any 

 ■other drug. 



3. Kusso {flores hoso). This is to be given in doses of from 

 •3 to 5 gms., diluted with milk, repeated three or four times at 

 intervals of three-quarters to one hour. This should be mixed 

 •or followed with a small dose of castor oil. 



Pomegranate (cortex granati), in the shape of the macerated 

 decoctions of 30 to 100 gms.; pumpkin-seeds crushed and macer- 

 ated in hot water; areca-nut grated up fine, in from 20 to 30 gms.; 

 oxide of copper, picronitrate of potassium, tu*pentine, chloroform, 

 are all taenaifuges. These agents are much less efficient than the 

 preparations mentioned above.
