The reason for using a larger and a less handy machine than seems absolutely necessary to perform a delicate operation is, because nearly all syringes suck up a portion of air, which, when the instrument is almost empty, comes forth. Now breath or atmosphere, or gas of any kind injected into a living vessel, speedily destroys life. To prevent so fearful an accident the enlarged capacity of the syringe is recommended.
The water being injected, should the pulse regain its inflammatory character, mingle half a drachm of aconite root, in powder, with every subsequent antispasmodic draught. The ethereal drenches must be continued, because pain of the intestines is always obstinate, and we cannot be certain how far spasm may cause the agony, seeing that a form of colic always attends on enteritis.
| Aconite root, in powder | Half a drachm. |
| Sulphuric ether | Three ounces. |
| Laudanum | Three ounces. |
| Extract of belladonna | One drachm. |
| (Rubbed down in water) | One pint and a half. |
These drinks should be administered as the pain, pulse, and the general appearance seem to demand them; they may be employed every quarter of an hour if requisite. When the pulse is quiet, withdraw the aconite; should the pain subside, remove the belladonna. The ether and laudanum may be diminished as the horse appears to be more comfortable.
Should the symptoms denote a dead, lingering pain in the abdomen, after the administration of the eighth drink, procure some strong liquor ammonia. Dilute this with six times its bulk of cold water. Saturate a stout cloth with the dilution; lay the cloth upon several folds of rug; obtain four resolute men with not very sensitive eyes or noses, and let them hold the cloth close to the animal's abdomen.
THE APPLICATION OF AN AMMONIACAL BLISTER IN ENTERITIS.
The action of the ammonia must be from time to time observed. It is a most powerful agent; in certain states it can blister in ten minutes; in other conditions, it requires half an hour to take that effect. It is very uncertain; but, if held too long, it may dissolve the skin and leave behind a fearful sore, which will establish a lasting blemish. He who employs it will understand he is using that which must not be abused. The removal of the cloth allows the ammonia to evaporate, and, consequently, at any moment effectually checks all further action.
When all is accomplished, should the progress of the disease be effectually stayed, but the cure not be complete, sprinkle on the tongue the following powder every second hour:—
