2. The shorter pair of forceps is now applied in a simi- 
lar manner to the opposite lip of the external os uteri. Trac- 
tion is applied to both pairs of forceps, the one being pressed 
to the right and the other to the left, so that the os uteri is 
exposed to view. 
Extra small double curve taper point, size 14 inches long 
and 3/16 inch diameter at point. Small double curve, size 
14 inches long, 5/16 inch diameter. Medium double curve, 
size 14+ inches long, 7/16 inch diameter. Large double 
curve, size 24 inches long, 34 inch diameter. Extra long, 
single curve taper point, 22 inches long, %4 inch diameter at 
point. 
3. The Albrechtsen uterine catheter of proper size is 
now introduced carefully through the cervical canal. No 
force is used. The catheter is revolved upon its long axis, 
is pressed towards the left or right, and upwards or down- 
wards, or may be partially withdrawn and then pushed for- 
ward at a different angle, until the tortuous canal is finally 
found and followed into the uterine cavity. If this is not 
readily accomplished, introduce the Palmer’s Uterine dila- 
tors carefully and trace the cervical canal. Open the dila- 
tors and thus dilate the canal somewhat, and press aside the 
transverse mucous folds. Repeat the application of the 
dilator until the uterine catheter can be safely and easily 
passed. The uterus is next douched by means of an ordinary 
fountain syringe, with a two per cent Lugol’s solution, or 
other disinfectant, according to the desire of the operator. 
In cows which are sterile and where the uterus is slightly 
enlarged from chronic endometritis, the douching should 
occur one or two hours before breeding and all the solution 
forced out by rectal pressure. In other cases, where there 
is pus in the uterus, the douching may be repeated fre- 
quently.
