with 2% bacillol or carbolic acid. The solution should 

 have a temperature of approximately ioo° F. 



We advise that a suitable galvanized iron, or other pail, of 

 about 5 gallons capacitj'.be procured, and fitted with a metal 

 faucet. A lo foot pure gum horse stomach tube should be 

 attached to the faucet. The stomach tube is by all means the 

 best appliance known to us for conducting the fluid from the 

 container to the desired part. When washing the external 

 parts, the operator can shut off or control the rate of flow by 

 placing a finger over the outlet of the tube. The tube is smooth 

 and pliable, so that its introduction deeply within the vagina 

 can work no injury, and yet has enough rigidity that it can be 

 introduced through the vulva into the deepest part of the vagina 

 without introducing the hand. 



A heavy wire is tightly stretched just behind the row of cows, 

 and a puUy and hook placed upon it. The wire should be 

 stretched by means of a heavy screw bolt, so that the track can 

 be so tightly stretched that it will not materially sag in the 

 middle when loaded with the five gallon pail. The pail contain- 

 ing the solution for washing or for irrigating the vulva or vagina 

 is then suspended from the pulley, the stopcock opened, and the 

 work carried out. 



We believe it desirable as a rule, to introduce the remedy to 

 the deepest part of the vagina, and not content ourselves with 

 irrigating the vulva only. The findings of Ostertag and others, 

 that the infection sometimes gains the uterine cavity, suggest 

 that in some cases the irrigations must extent into that cavitj'. 

 After the outside is well washed, the operator may open the vulva 

 with a thumb and finger, and flush it with the same solution, 

 but it is better, in our judgment, to disinfect the vulva after the 

 vagina has been irrigated. The vaginal irrigation is to be per- 

 formed by inserting the tube, by a somewhat rotary movement, 

 through the vulva, deeply within the vagina, where it is gently 

 maintained until the vagina is well filled. When the vagina be- 

 comes thoroughly distended, the fluid obliterates the mucous 

 folds and reaches every part. This sometimes requires 2 or 

 more quarts of solution. Ordinarily about 5 gallons are required 

 for washing the external parts or irrigating the vaginae of 15 

 cows. The complete handling of 50 cows for one day can be 

 accomplished by one man in about 2 hours. The cost per day 

 for disinfectants by this plan is about 2.5 cents per cow.
