to strength and magnitude, or indistinct, the stream of the blood failing also indicates that the strength is sunk), or from the malignity of the inflammation; for sometimes it will not remit, but the constriction continues strong. But if none of these circumstances contra-indicate, and if the patient be in the vigour of age, we may wait until a change takes place, especially if the atmosphere be mild. But if the flow of blood stop before a sufficient evacuation has taken place (this happens from fear, deliquium animi, and coagulum, or too tight an application of the bandage), we must attend to each of these causes, rousing from deliquium with strong-scented things, slackening the bandage when too tight, and a coagulum may be dissolved by pouring in oil, or by rubbing it with the fingers. The rest of the apparatus for phlebotomy is known to everybody. But these things apply to venesection at the bend of the arm. When we would abstract blood from the forehead as for headache, having first used fomentations, we apply a bandage round the neck, placing a finger over the windpipe to prevent suffocation, and when the frontal vein is properly filled we divide it with the point of a lancet or scalpel. In the same manner we may open the external jugulars for chronic ophthalmy, producing a discharge of blood with the concave part of the scalpel. The vessels also below the tongue we open transversely for angina, but without the application of any bandage. Some also open in like manner the veins which appear in the great canthi, as for chronic affections of the head or eyes, in which cases they also sometimes rupture the vessels within the nostrils either by rubbing them with the extremity of a specillum, or by tickling them with rough substances. They also open those behind the ears for the affections about the head; and those about the top of the thighs, as in affections of the kidneys; and those in the extremities they also open, after by the application of the ligatures to the parts above, by friction in the case of the hands, and walking in that of the feet, the vessels having become distended with blood; in affections of the spleen opening the vessel in particular between the small and middle finger of the left hand, and in affections of the liver those of the right hand; for the evacuation of the extremities, being from a distance, occasions a more powerful revulsion. In ischiatic diseases, and those of the uterus, they open the vein in the foot above the inner toe. * * * * * COMMENTARY. We have to regret that our limits prevent us from doing more ample justice to the sound and enlarged views of the ancient physicians on this subject, and we must be content with making a few desultory observations and giving a few extracts. We have had occasion frequently to remark that Hippocrates practised venesection freely in various diseases. He has left no treatise, however, expressly on the subject.
