the windpipe. The needle of the syringe is then inserted in a downward 

 direction in tlie space between an\- two rings and tlie contents of the 

 syringe injected forcibly towards the lungs. A dab of sheep dip or 

 other antiseptic dressing may be applied to the wound after withdrawal 

 of the syringe. An ordinary hypodermic syringe of large size may be 

 used, but if it is fitted (as intra-tracheal syringes are) with short stout 

 needleii the preliminary incision of the skin may be dispensed with, i.e., 

 in the hands of an expert operator who by practice can hit the windpipe 

 between the rings every time. 



The vermicidal solution to be injected may be compounded as follows : — 



(i) Syrup of poppies 



Rectified oil of turpentine of each one fluid ounce. 

 Pure carbolic acid, ten drops. 

 Olive oil. two drams. 



Sufficient for eight sheep. Dose. twO' drams (i dessertspoonful). 



{2) Rectified oil of turpentine, one ounce. 

 Laudanum or chloroform, naif an ounce. 

 Carbolic acid, pure liquefied, ten drops. 

 Olive oil, half an ounce. 



Sufficient for eight sheep. Dose, two drams (i dessertspoonful). Half 

 doses of either prescription for young lambs. Two-third doses for 

 weaners. 



Fumigation or Inhalation for Lung Worm. — This treatment in- 

 volves the introduction into the air passages of some gaseous agent which 

 will have a poisonous effect on the worms lodged there, or by inducing 

 coughing will cause their expulsion. It is a rapid method of dealing with 

 large numbers, as a hundred or two at a time may be subjected to the 

 treatment. The process may be illustrated by instancing fumigation with 

 sulphur, although chlorine gas or volatilized formalin may be used with 

 equal safety and success. 



The sheep are placed in a woolshed or other building, all the opening.s 

 into which should be effectively closed. Bags may be stuffed into air 

 holes, louvres and other openings, and cracks and crevices in doors, floors, 

 ceilings, and windows may be pasted over temporarily with paper. Rock 

 brimstone or flowers of sulphur is ignited inside the building and kept 

 burning so giving off sulphurous acid gas (SOg-) . This is done perhaps 

 most conveniently by placing the ignited sulphur on an iron plate or 

 ."^hovel kept at a dull red heat by the flame of a lamp underneath. It 

 may be also vaporized bv placing it on top of a layer of live wood or 

 coal ashes on a shovel or plate. Two or three persons should remain in 

 the building .seated on their haunches at different parts so that they are 

 practically in the same position as the sheep with regard to the inhalation 

 of the sulphur flames. When the fume-laden atmosphere approaches the 

 unbearable for the men it will be time to throw open the doors and let 

 the sheep have some fresh air but they may be left in the building (with 

 open doors) until the fumes have dissipated. If any of the sheep cough 

 violently or are otherwise overcome they should be immediately removed 

 to the outer air and in no event should the inhalation be pushed to the 

 point of suffocation. It is better to repeat the process at an interval of 

 a few davs rather than run anv undue risk.
