A NOMA LIES IN GESTA TION r 6 7 



of "spaying." The right horn and its ovary, with a portion of the body of the uterus 

 and vagina, were absent. A mass about the size of a man's head, enveloped in false 

 membranes, was situated in the left iliac region, and connected with the left horn of the 

 uterus, which was still continuous with its ovary and the vagina. On dissecting the 

 tumor, the osseous remains of seven Pigs were discovered, enclosed in separate cavi- 

 ties. Seven heads and all the bones were collected. They were, however, denuded of 

 all soft parts, as if they had been subjected to maceration. 



Symptoms, Course, a?id Termifiations . 



We have already to some extent indicated, in recording the history of 

 several of the most interesting cases of extra-uterine pregnancy mentioned 

 in veterinary literature, the character of the symptoms, and the termina- 

 tions which mark this accident. The symptoms are generally those of 

 conception and gestation. The ovum grafts itself on some part with 

 which it chances to be in contact ; an embryo results, the placenta being 

 attached to the neighboring textures and developing with the increase of 

 the young creature ; these changes being accompanied by the ordinary 

 external signs of uterine pregnancy. In the majority of cases, tl^^e par- 

 turition should occur in the usual course, the premonitory indications of 

 that phenomenon are very slight or altogether absent ; though the animal 

 may now and then make expulsive efforts, which continue perhaps for a 

 few days, and then subside gradually, or recur at intervals. In the most 

 favorable cases, when the fcetus perishes, it becomes enkysted and mum- 

 mified ; the fluids and soft parts are absorbed, and the remaining por- 

 tions become dry and parchment-like ; or the creature may undergo a 

 process of calcification by the deposition of carbonate and phosphate of 

 lime in its tissues, which preserve its shape, and convert it into a " litho- 

 paedion " or " osteopjedion." In this condition the foetus may remain 

 for an indefinite period in the abdomen of the mother, without causing 

 much, if any inconvenience : indeed, a most perfect state of health may 

 exist, and the animal become remarkably fat, or it may conceive and 

 bring forth as favorably as if nothing abnormal existed ; the indications 

 of anomalous gestation being only discovered by chance when the animal 

 dies from some disease which has no relation to this accident, or is killed 

 for food. 



Such a happy result of the accident is, however, very far from being 

 % the rule, and the chances are many that fatal termination will be the 

 consequence of extra-uterine gestation. Expulsive efforts or other causes, 

 may lead to rupture of the kyst in which the foetus is contained ; and 

 this, with the fluids and deh'ts of membranes, falling into the abdominal 

 cavity, may give rise to such a severe form of peritonitis that death will 

 ensue in one or two days. In other instances the kyst inflames, and 

 suppuration is established, with putrefaction and partial solution of the 

 fcetus ; and if the mother does not at once succumb to pyaemia or septi- 

 kaemia, adhesions and communications are formed between the kyst and 

 neighboring organs, and the remains of the yopng animal, chiefly the 

 bones, are expelled either directly, as by ulceration of the abdominal 

 I walls after the development of an abscess, or indirectly, as through the 

 intestine, etc. After the foreign matters have been completely, or even 

 only partially, eliminated in this way, the fistulous openings by which 

 they escaped ciatrize after a variable period of suppuration, and the female 

 recovers — as has been observed in Sheep and Goats. 



More frequently, however, it loses condition, becomes emaciated and 

 feeble, and perishes in a state of marasmus ; or it succumbs to hectic
