camphor, equal parts ; dose a teaspoonful in mucilage or gruel 

 daily. Oil of turpentine i oz.; olive oil 2j^ ozs. Though these 

 agents exhale from the lungs their action is not very effective on 

 the lung worms. They are much more effective on the intestinal 

 parasites. 



Fumigations are somewhat better. The affected sheep are 

 turned into a close room, in which sulphur mixed with a little 

 alcohol is burned in an earthenware plate, set in a vessel having 

 a little water in the bottom. This obviates risk of fire. The 

 fumes are allowed to pervade the whole buildiug, and the ad- 

 ministrator stays in the room and breathes the gas, so that he can 

 cover up and extinguish the sulphur whenever the concentration 

 becomes irritating. Violent coughing or .sneezing is the signal 

 to stop the burning, and in case of danger to throw open doors 

 and windows. Otherwise the sheep should be left to breathe the 

 fumes for J^ to i hour, and this should be repeated daily for a 

 week. The first day's treatment charges the liquid secretion with 

 the gas, kills all the worms within reach and acts as an astringent 

 antiseptic. Every successive fumigation reaches farther, until 

 the ultimate receisses may be reached. After a fortnight a second 

 course of fumigation may be resorted to to kill off the em-bryos 

 that may have hatched from the eggs left over. 



Other fumigating agents have been u.sed such as chlorine gas, 

 formed by mixing common salt, black oxide of manganese and 

 sulphuric acid, but this is much more irritating and dangerous. 

 Others use the fumes from woolen rags, horns, hair, feathers, 

 leather, empyreumatic oils, tar, juniper berries, asafoetida, etc., 

 these being placed on a red-hot shovel, or in an iron pot contain- 

 ing red embers. 



Tracheal Injections. These are the most effective measures, 

 and may be thrown in with the aid of a hypodermic syringe be- 

 tween the rings of the trachea. The nozzle, previously dipped in 

 carbolic acid, should be inserted first, if poissible in the interval 

 between two rings and then the charged syringe is connected and 

 discharges its contents. The simplest injection is a i per cent, 

 solution of common table salt in distilled or boiled water, which 

 may be used freely. lyevi found the following very effective : 

 iodine 2 parts, iodide of potassium 10 parts, water 100 parts by 

 weight. Dose Y^ drachm , which may be encreased by Yq, drachm
