organs of sense in some cases. These anidian monsters have not at- 

 tracted much attention ; so we will venture to give a short analysis of 

 some instances recorded in the annals of Veterinary Science. 



In the Rectieil de Med Vetirinaire for 1828 (p. 370), Saussol describes the case of a 

 Cow three months in calf, and which, when harnessed to a carriage, fell on its abdomen 

 with great force against a stone. After this accident it lost condition, pined away, and 

 at last died. When opened, instead of an ordinary foetus, there was found an oval- 

 shaped consistent fleshy mass, of a reddish violet color, floating in a rusty-tinted fluid, 

 and which had obtained its nourishment by means of a single cord — no doubt emana- 

 ting from some cotyledon. This tumor contained the skeleton of a fcefiis, the bones of 

 which were normal and not displaced, being held together by means of ligaments. 



Leaux ( Journal de Med. Veterinatre de Lyon, 1846) states that a Cow seven months 

 pregnant, after two days' violent straining, ejected a dead foetus and a large tumor, and 

 died immediately afterwards. The tumor weighed five kilogrammes, was of no par- 

 ticular shape, was reddish-brown in color, soft but very vascular and covered by a fine, 

 apparently pseudo-membranous, envelope. No trace, of peduncle or uterine adhesion 

 could be detected. The whole mass was of a fibrous texture, and composed of a mul- 

 titude of small vesicles containing an amber-colored serqsity. 



The Reciicil de Med. Veterinaire for 1858, contains the description of an anidian 

 monster found in a sheep which had given birth to a dead lamb, and was sacrificed. 

 This monster had neither head nor tail, was about two feet long, and sixteen -inches 

 broad at the widest part. The limbs were rudimentary, without any trace of digits, 

 and there was neither anus, vulva, or scrotum. A protuberance took the place of 

 the neck and shoulders ; while in the centre of the mass was only a cavity filled with 

 serum, in which floated a rudimentary stomach and intestines. There was no trace of 

 liver, spleen, kidneys, diaphragm, heart, or lungs, and there were a few bones, sup- 

 posed to be misshapen ribs; the remainder was composed of infiltrated connective 

 tissue. 



Mr. Snowdon, in the Veterinarian for 1856 (p. 218), states that on January 30th a 

 Cow produced a healthy female calf. _ Nothing unusual was observed during the day, 

 but about six p.m. the animal appeared to be in pain, when Mr. Snowdon was called. 

 He found a membranous sac hanging from the vagina, to nearly as low as the Cow's 

 hocks. This was punctured, but only a small quantity of fluid escaped, though a mole 

 appeared, which was attached to the placental membranes by an umbilical cord. This 

 was divided, and the animal continuing in pain, an examination was made/^r vaginam, 

 when another calf was found in the uterus. This was delivered, when it was discovered 

 to be a male calf, well developed, but dead. The Cow did well afterwards. The 

 anidian monster was in shape a flattened ovoid, about two inches in thickness, and six 

 inches by four in size. It was covered with long red hair ; though at the border, where 

 the umbilical vessels enter, was a hairless spot. On the opposite border was ' the rudi- 

 ment of a lower jaw, containing four well-developed incisor teeth, three of which had 

 cut the gum. Above this was a small cartilaginous ear, and near it something like an 

 eyelid. Several bones were contained in the mass, one of which had the shape of the 

 bones of the skull ; though, as a whole, it felt spongy and elastic. Its weight was 

 fourteen ounces. 



In the Annales de Med. Veteriiiaire for 1859, May mentions having delivered a normal 

 calf, and afterwards the Cow expelled an oval mass the size of a child's head, covered 

 with a fine velvety skin, and showing at one point an umbilical cord. This skin en- 

 veloped a vascular spongy tissue, mixed with muscular and glandular portions, and in 

 its centre was a small soft bone about an inch in length, 



Lavocat {Journal de Vet. du Midi, 1866) relates that having delivered a Cow of a 

 well-formed calf, and before the removal of the membranes, a kind of downy ball was 

 expelled, which was only attached to the latter by a vascular prolongation, comparable 

 to an umbilical cord. The mass was oval in shape, as large as a lamb's head, every- 

 where covered with hair, and at the middle was what appeared to be a regularly-formed 

 umbilical cord. At one of its extremities was a shallow cavity terminating in a cul- 

 de-sac, the irregular margin of which bore the incisor teeth projecting beneath the gums. 

 There was no trace of thoracic or abdominal cavities or organs ; neither was there 

 brain, spinal cord, or nerves. Some bony fragments were found, among which were the 

 rudiments of a lower jaw bearing the teeth already mentioned. The remainder of the 

 tumor was made up of very vascular cellulo-adipose tissue, the meshes of which were 

 filled with serosity. 



In the Veterinarian (vol, xliv., p. 275), Mr, Creswell describes an anidian monster 

 produced by a white short-horn Cow, two hours after delivery of a healthy and well- 

 developed bull-calf of a roan color. This monstrosity was round, and about the size of
