. The sterility of cows, its causes and treatment. Infertility in animals; Cows. 69 when the arm is introduced in the vagina, but do not mind the subsequent operations. I use for infusions and for the removal of the uterus con- tents a thickwalled rubber catheter (Fig. 17), which is closed at the end but has two openings on the side. Such a catheter is easily introduced and does not clog up; another advantage. Fig. IS—Speculum. of it is that it does not become closed by sharp turns or by the pressure of the cervical canal. If the canal is so narrow that I can not introduce this catheter, then I try to dilate it by the use of a bigger one. If even that is of no use, I em- ploy a metal tube as a mandrin. (Fig. 18.) After I have in- troduced the catheter with the help of this instrument I draw it so far back that its end is on the os uteri internum. The rubber catheter is then in the uterus proper and the metal tube keeps open the cervical canal. The contents of the uterus can be then easily removed after they are diluted with water. To remove the contents completely it is neces- sary to massage the uterus from the rectum. It is quite possible to clean the uterus by repeated infusions. If tissue remnants or necrotic cotyledons are found which cannot pass the catheter, one must try to press them through the cervix, possibly after a dilatation of the latter with the knife. For the irrigations I employ first pure luke-warm water or weak solutions of lysol (J4—1/10%), and afterwards a solution of iodine and potassium iodide in the relation of 1 :3 :97 or 1:3 :200, which, however, has to be removed Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Albrechtsen, Jacob, 1859-1921; Wehrbein, Heinrich, 1889- tr.
