IMPERFORATE VAGINA. 423 



moved on the 29th, on April ist, and on the 3rd of May. On the 5th 

 May recovery was perfect. 



Remarks. — Plugging of the deeper portion of the vagina, as practised 

 in these two cases, is the best treatment for prolapsus of the uterus in 

 the bitch. When carefully performed it is well borne, and if the 

 pessary is rejected there is no difficulty in renewing it. Since i8g6 all 

 cases of prolapsus of the uterus have been treated in this w'ay in our 

 practice. We have never had to practise amputation. 



MYXOMA OF THE UTERUS. 



132. A ten-year-old bitch, brought for examination on the ist 

 February, 1892. 



Two days previously a large swelling had appeared below the vulva. 

 The last oestrum had occurred six weeks before. 



A month before this bitch had been seen to make frequent straining 

 efforts ; urine was passed frequently, but in small quantities ; the abdo- 

 minal muscles contracted violently, and remained contracted for a 

 certain time after emission of urine. No treatment was adopted until 

 the 2gth January, when a swelling was seen behind the labiae, which 

 was at first regarded as " the everted uterus containing one or more 

 young." 



The swelling was partly covered by the long hair of the tail, and on 

 exposure appeared ovoid, smooth, of fairly firm consistence and reddish 

 colour ; its upper part was rounded ; it diminished in size towards the 

 base, which was continued by a pedicle the size of a lead pencil, issuing 

 from the orifice of the vulva. It measured five inches in length and 

 six in circumference. In order to determine the point of insertion, 

 slight traction was exercised on the growth ; the pedicle was fixed to 

 the right side of the neck of the uterus, the surface of implantation 

 being scarcely one sixth of an inch in diameter. The patient was 

 lively, and only seemed to have a little difficulty in walking. 



The tumour was excised with the knife, the base of the pedicle being 

 ligatured with silk, and the growth divided immediately behind the 

 ligature. 



The tissue of this tumour was soft, whitish towards the centre, 

 marbled with red towards the periphery. Dotted through it were little 

 cavities containing a reddish liquid. 



On microscopic examination it appeared formed of rounded, fusi- 

 form, or branching cells, with one or more nuclei, contained within a 

 highly refractile, almost amorphous stroma. Its peripheral layer 

 contained considerable numbers of vessels. It was a myxomatous 

 tumour of the variety known as cystic myxoma. 



IMPERFORATE VAGINA. 



133. Four-year-old bitch, entered hospital on the 23rd June, il 



For the previous week this animal had been constipated, and made 



violent attempts to defecate. It showed marked wasting. From 



between the anus and vulva a fluctuating swelling the size of a large
