PROBE—is a silver instrument used by SURGEONS and VETERINARIANS, in sounding the depth of cavities, sinusses, fistulas, and wounds: they are, upon unexpected emergencies, so very frequently useful in the country-house, or remote residence of a sportsman, that it should never be without _this_, and some _other_ trifling instruments of little expence; exclusive of lint, tow, ointments, tinctures, and a few other cordial and diuretic medicines, for which there is sometimes a sudden and unexpected occasion. PULSE.—In all dangerous and inflammatory diseases of horses, much information may be derived from the state of the PULSE; in addition to the observations to be made upon the difficulty of respiration, the heaving of the flank, the heat of the mouth, and the state of the eyes. It seems, by the nicest observations, that the pulsations in a healthy horse seldom exceed from forty to forty-five in a minute; exceeding which in any material degree, there is then reason to believe, inflammatory heat is predominant in the frame, and that fever is rapidly advancing in proportion to the increased velocity of the blood. FARRIERS in general, either from a want of attention, or want of judgment, are most culpably deficient in this part of their professional examination; upon a competent proficiency in which, must solely depend the CONSISTENCY, or _impropriety_, of repeated bleedings, in all cases of high and increasing inflammations, where REPETITIONS are absolutely indispensible for the preservation of life. PURGING—is an operation with horses, upon the propriety, consistency, danger, and utility of which, various opinions have been opposed to each other for half a century past; these, after the public experience of the last fourteen years, seem to have centered in an acknowledged preponderation of its occasional use; and that without its frequent salutary introduction, certain diseases are neither to be prevented or cured. The absolute necessity for sometimes PURGING, is not only now universally admitted, but the practice as generally adopted; the first step to a successful termination of which operation is, to adapt (by every possible degree of precaution) the strength of the physic to the _size_, _state_, and _constitution_ of the HORSE, as well as an eye to the particular cause for which the purgation is become necessary. Proper attention paid to these leading circumstances, and due care observed during its process, no apprehensions of danger need be at all entertained.
