any quantity of the infused solution which may be retained 
in the uterus. As a matter of fact it is nearly impossible to 
remove all the fluid from the horns, where it then prevents 
the contraction of the uterus, and facilitates an infection. 
If the secundinae are decomposed I do not advise a pre- 
mature attempt at removal, but think it better to wait until 
it is possible to pull out the placenta in its entirety and with- 
out violence; a careful irrigation should follow. 
If an infection has taken place and a metritis is found, 
then it is important to bring this metritis as quickly as possi- 
ble to a conclusion. The contents of the uterus have to be 
removed, and the organ carefully cleaned through disinfect- 
ing irrigations. Till now this has been a difficult task; the 
contraction of the cervical canal and the restlessness of the 
animals have made the introduction of the catheter, which 
was, moreover, inefficiently constructed, very difficult. The 
whole technique has been very unsatisfactory. One has 
generally been satisfied to infuse a solution of carbolic acid, 
lysol or creolin, and has not taken care really to clean out 
the uterus. This mistake can not be remedied by the use 
of strong disinfecting solutions. On the contrary, the in- 
fused fluid can be harmful by increasing the resistance which 
the uterus has to overcome in its involution. 
The important measure, therefore, is to remove all the 
contents of the uterus, so as to make its contraction easy. 
The following technique is an efficient and an easy one: 
Fig. 14--Sharp hook. 
A sharp hook (Fig. 14) is inserted into the cervical canal 
and the cervix drawn into the vulva; a speculum (Fig. 15) is 
then put into place. With two or only one big forceps (Fig. 
16) the cervix is then securely held, so that a catheter easily 
can be introduced into the uterus. The cows feel pain only
