pills or as an electuariiim, one may give Fowler's Solution 

 for 5 to 8 days, morning and evening, 1 to 2 tablespoon sful 

 for an adult liorse or 1 teaspoonful for a foal, in oats, bran, 

 or in the drinking water. Oleum terebinthinse (50-100 gm. with 

 300 gm. of castor oil) lias likewise been found advantageous; 

 also arecanut (for adult horses 100-250 gm., for foals 10-50 gm., 

 or 3 times daily, 1-2 tablespoonsful or 1 teaspoonful with moist 

 short cut feed, bran-mash or as an electuary). Santonin (10-25 

 gm. in pills or as an electuary), which, however, is quite expen- 

 sive, may be used for horses, with the exception of very young 

 foals, given in castor oil or followed by the latter. Carboneum 

 sulfuratum (carbon bisulphide) is useful against roundworms 

 as it is also against gastrophilus larvae (see page 456). Rehaber, 

 who found this drug more effective than anything else, uses it 

 in doses of 50-100 gm. in one dose with 200-300 gm. of castor oil, 

 without any evil consequences. 



Gasteiger had good results in calves with the following 

 drugs : Tartar emetic 3-5 gm. dissolved in 125 cc. distilled water ; 

 1 tablespoonful in milk every 3 or 4 hours, until the desired 

 effect is brought about; arecanut with flores cinae (mixed with 

 the feed, calves up to 3 weeks 10 gm. : 5 gm. ; up to 5 weeks 15 

 gm. : 7.5 gm. ; over 5 weeks old 20 gm. : 10 gm.). The mixture also 

 makes a very good appetizer. This mode of treatment may also 

 be used in lambs ; the doses must, of course, be smaller ; or lambs 

 may also be treated with the same drugs recommended against 

 gastric strongylosis (see page 458). For hogs are recommended: 

 Arecanut (adult animals 10-20 gm., young pigs 5-10.0 gm., with 

 honey or flour as an electuary), oil of turpentine (daily 1 tea- 

 spoonful in mucilage), picronitrate of potash (0.2-0.5 as an 

 electuary), benzin (10-20 gm., with bran or flour as an electuary). 

 After a few hours laxatives are administered (calomel, aloe, 

 castor oil). Dogs and cats should receive the same treatment 

 recommended against tapeworms (see page 471), also very ser- 

 viceable are santonin (for dogs 0.05-0.2 gm., for cats 0.02-0.05 

 gm., in powder, followed by castor oil or still better combined 

 with it), or pastilli santonini (each one containing 0.025 gm. 

 santonin), flores cina^ (2-10 gm. as an infusion), th^miol (0.2-0.5 

 gm. in pills), and filmaron oil (2-5 capsules at a dose, followed 

 by castor oil). 



Prophylaxis. The spread of infection may be prevented by 

 separating the sick animals, collecting, burning or burying the 

 feces and drying out the place where the sick animals are kept. 

 Mother animals harboring Ascaridag should be relieved of them 

 before delivery, and kept separated. It is advantageous to ex- 

 amine, microscopically, the feces of larger herds in order to pre- 

 vent the spread of the disease. Gasteiger recommends, aside from 

 the destruction of the feces, that the floor of the barn be made 

 waterproof, so that it can be swept with iron brooms and can be 

 covered with sand. Before removal, the latter is moistened with
