hypertrophied, and must be incised before delivery 
can be effected. 
Want of Muscular Power to Expel the Feetus. 
This condition is seldom, if ever, present at the 
beginning of parturition, but it is often found, that 
after an animal has been straining for a considerable 
length of time, with an abnormal presentation, that she 
becomes exhausted; the muscular fibres of the uterus, 
for the time being, being paralysed; and although the 
foetus be brought to a normal position, the parent 
makes no effort to expel it. 
In some animals, especially those in a plethoric 
condition, the muscular tissue of the uterus undergoes 
fatty infiltration. During pregnancy, in such subjects, 
this paralysed condition is much more easily brought 
about. 
In this case, the animal should be allowed to rest 
for several hours, and stimulants and gruel judiciously 
administered. When her strength has been partially 
restored, traction, gently applied, will very often com- 
plete delivery.
