His indications are the length of the uterus, its width ex- 
pressed in centimeters, and its contents approximately ex- 
pressed in liters and in grams. The measurements are taken 
according to the length of the arm and the width of the hand. 
When one considers that the uterus of a three months old 
pregnancy in one cow may be larger than the uterus of a 
three and a half months old pregnancy in another cow, that 
the intestines exercise a strong influence over the situation 
and the shape of the pregnant uterus, that the time of con- 
ception may differ even if the mating has taken place at the 
same time, and that the duration of pregnancy may be 
Setween 210 and 321 days, then it becomes evident that exact 
“culations of the age of pregnancy are rather vain. It is 
yossible, anyhow, to pay so much attention to the dimen- 
of the genital organs, if one has to examine about 50 
.in one hour. 
.t is generally possible to find pathologic conditions in 
vs which are sterile or have irregular estrum periods. The 
sions may be present in different locations, as in the uterus, 
he cervix, in the os uteri, in the vagina, in the ovaries, in 
oviducts or in the surrounding tissues. 
Examining per rectum one will often find the uterus 
enlarged to a variable extent, its walls more or less thickened 
or edematous, and containing a thick exsudate. In the quite 
frequent cases of accumulations of pus in the uterus, this 
organ is as a rule very much enlarged and protruding into 
the abdominal cavity, its walls are thickened sometimes, how- 
ever, thinned, and one can easily feel fluctuation. Gererally 
discharge from the vagina is present. 
In the majority of cases one will not find contents in the 
uterus, but only an enlargement of the organ and thickened 
walls. The horns of the uterus are generally asymmetrical 
and rather long; they protrude into the abdominal cavity and 
are felt as uneven, knotty cords; they can also be short, and 
then more thick. Under the palpitation they contract, which 
is specially noticeable in the diseased horn.
