STRUCTURE OF THE OS AHD CERVIX UTERI. 715 
hot and tender, and of sufficient size to raise the part 
some quarter or half inch above the plane surface. These 
tumours generally attain the size of the palm of the hand 
before taking on an active action. They may also be 
followed by a quiescent period. Suddenly, and so far as can 
be determined, without any special cause, the whole of the 
indurated substance, consisting of the tumour and skin 
covering it, appears to perish en masse. Sloughing follows, 
and a large ragged cavity with undermined edges is pro¬ 
duced, which corresponds in size to the circumferent boundary 
of the original tumour. More or less infiltration of the 
surrounding tissues necessarily exists. Although the everted 
edges of the sore are undermined with tuberculous matter, 
yet they do not exhibit any change upon their external 
surface beyond being a little nude of hair. The surface of 
the sore generally presents a brown or brick-red colour, and 
exudes a dirty, sanious, grumous fluid, which excoriates the 
skin over which it passes. After three or four days the sore 
shows a tendency to scab, this being of a brown colour, and 
but lightly attached, and that principally in the centre. Its 
attachment, indeed, gradually decreases towards the margin, 
and falling a little short of reaching the boundary line of the 
sore, a portion of the ulcer is left uncovered. In this im¬ 
perfect attempt at healing the ulcer continues to exude 
matter, and to go on increasing in size until checked by treat¬ 
ment.

STRICTURE OF THE OS AND CERVIX UTERI 
DURING PARTURITION.—OBSERVATIONS ON 
OPERATION BY INCISION FOR SAME. 
By A. E. Macgillivray, V.S., Banff. 
In speaking of stricture of the os and cervix uteri during 
parturition, I do not mean at all to refer to the spasmodic 
contraction of these parts during labour, which is no rarity 
to any practically experienced veterinary surgeon. 
Bv stricture I mean the existence of a permanent unyielding 
contraction of material, either a hard fibro-cartilaginous or 
soft and thickened fleshy material the result of or accompanied 
by disease of the parts referred to. In some cases, however, 
I am almost certain that the stricture is congenital. 
Where the contraction of the os uteri is the result of prior 
disease, it will generally be found of a hard fibroid nature ;
