After cauterizing the second section it isagain withdrawn in like manner, and so on untilthe internal os is reached, and the whole of theuterine cavity has been submitted to the action ofthe current. The platinum sound is limited in its use, for con-trolling uterine haemorrhage, to conditions where theuterine canal and cavity is narrow, allowing fair con-^tact with the endometrium, since contact is necessary — 171 — for effective cauterization ; but, where the cavity islarge and dilated, the sound will prove ineffective asan electrode for the control of haemorrhage, and itbecomes necessary to resort to sectional cauterizationwith the carbon electrode. Hence, it will be under-stood that the main advantage of the carbon electrode. Fig. 46.—Dr. Apostolis Carbon Electrodes for Sectional Cauterization. is that its diameter allows better contact with thesurface to be acted upon, and the concentration of thelocal action of the current upon a limited surfacemakes it more decided with the same strength of cur-rent than if spread over the whole area at once. It may be sometimes difficult to introduce the pro-per size of this electrode through the cervical canal,which may be narrow when the cavity is much dilated,and, though it is not done by Apostoli, it will be — 172 — advisable to dilate the cervix gently with the steedilator when necessary for this purpose. Steel Electrodes Specially Prepared to Resist theAction at the Positiye Pole.—To lessen the expenseof the electrical outfit, the author introduced to theprofession about three years ago, a number of elec-trodes made of steel which had been submitted to aprocess (unknown to him) that prevented oxidation,and resis
