PATHOLOGY OF GESTATION. 



turitiou had arrived, it was so wasted that Liautard was again called in. It was then 

 observed that the Cow almost every instant brought its limbs together under the body, 

 arched its back very mach, and made feeble but long-continued expulsive efforts, which 

 were immediately followed by the escape of a small quantity of odorless seruin. From 

 time to time, also, there appeared in the right flank a variable-sized tumor, which did 

 not look unlike the transient prominences the foetus makes during the later period of 

 pregnancy ; this appearance was accompanied each time by 2. glott gloti sound. Abdom- 

 inal exploration did not discover the foetus in this tumor; but direct exploration, 

 which was easily made, proved that the kyst recognized eleven months previously had 

 become considerably increased ; while the rupture of some fibrous bands during this

investigation, allowed the escape of some dozen litres of fluid. No foetus could be dis- 

 covered in the uterus, but there were numerous kysts, some agglomerated, others iso- 

 lated, and which made the interior of the organ feel lumpy at various points. Several 

 of these kysts were doubtless ruptured during the manipulation, for when the arm was 

 withdrawn there was an emission by the vulva of another dozen litres of fluid. This 

 condition of the uterus accounted for the apparent pregnancy. No treatment was at- 

 tempted, and eight days afterwards, the Cow having died, an examination was made 

 of the carcase, when the following lesions were noted : On removing the digestive 

 organs the uterus appeared as an enormous irregular mass, measuring from the cervix 

 to the extremity of the horns three feet seven inches ; an incision made in its lower
