Side of them. It will be necessary here to obtain possession of 

 the head.' Introduce a finger into the mouth of the foetus, or 

 get the hand round the mouth, using force sufficient to bring the 

 head up into the passage, and deliver the lamb. 



(4) Where the side of the foetus only can be felt, it must 

 be turned to its natural position. This requires judgment, 

 patience, and skill on the part of the operator. No iron-clad 

 rule of procedure can be laid down. The operator must manipu- 

 late the parts until he can obtain possession of a limb, which 

 should be brought up into position and another one sought for, 

 which, when obtained, the foetus can be extracted. Either hind- 

 legs or fore-legs are sufficient, — of course, if the fore-legs are 

 brought into position the head must present properly, as in 

 paragraph three. 



(5) "Where the back of the foetus presents itself the same 

 procedure recommended in paragraph four must be employed. 



(6) Where the breech presents, the hind-legs being re- 

 tained, repel the foetus, standing it on its head in the uterus; 

 reach for a hind-leg, bring it up into the canal, then bring up the 

 other, and extract the lamb by pulling it out backwards. 



(7) Where the foetus is too large for delivery. These 

 cases call for embryotomy, the foetus having to be extracted 

 piece at a time. Frequently, in these cases, if the operator can 

 disembowel the foetus the carcass will collapse sufficiently to per- 

 mit its being extracted. Where the head is enlarged (hydro- 

 cephalic), it must be punctured to allow the fluid to escape; the 

 head can then be crushed and delivery take place. Monstrosities 

 also come under this class. They frequently necessitate the use 

 of the knife on the foetus if the ewe is to be saved. 



In all cases where it is necessary to offer assistance to the 

 ewe in lambing, care must be exercised to see that no dirt or 

 foreign substances are introduced into the womb, which would be 

 liable to result later in septic poisoning and death to the subject.
