VETERINARY OBSTETR1CY. 141 
Leg-hanked — Twins, one a Breech Presentation ; the 
OTHER WITH ITS FOUR LEGS PRESENTED. 
In the year 1843 I received a letter from Mr. Cox, Y. S., now 
of Ashbourn, Derbyshire, wherein he mentions the following case. 
He says, “ a cow making no progress in parturition, we were 
requested to examine her, when we found the tail of one calf was 
to be felt (a breech presentation), and all the feet of the other calf. 
It being the first case of the kind that we had seen, we set to work 
and corded the hind feet of the latter, and pulled at them, at the 
same time pushing the fore legs and head back ; but from one of the 
hind legs not properly advancing, a further examination took place, 
when it was found that it had shot between the hind legs of the 
other calf, constituting what, by some, is called ‘ leg-hanked.’ 
The end of the hind leg that did not sufficiently advance was 
then loosed, and, by pulling at the other leg, it caused the fast one 
to come from between the hind legs of the other calf; after which 
it was again corded and brought up, and the calf readily ex- 
tracted.” 
Tn such cases as these, although Mr. Cox’s did well, yet I think 
it would be advisable for us, first, to get the hind leg that projects 
between the hinder legs of the other calf into its proper position 
before we attempted its extraction. If it should be possible to 
bring the head forward with the fore legs, the hind leg would 
follow in due course, and the breech of the one calf might be 
forced out of the way sufficiently for the other to pass : or, I think 
it would be quite as preferable to force the four legs out of our 
way, and to remove the calf that has its breech presented, first. 
Twins, one a Breech Presentation ; the other lying on 
its Back, with its Head and fore Legs presented, with 
ONE OF THE LATTER BETWEEN THE OTHER’S HIND LEGS. 
In these cases we must, first of all, try to get the fore leg that 
has passed between the hinder ones into its proper place : after which 
we may extract the foetus as it lies, or we may force this foetus 
back, and extract the other, as in a breech presentation.
