    tion, at least I have not been able to meet with the circumstance upon record, nor have my own observations afforded any instances of it. Arteries, however, are frequently involved in the sloughing of surrounding parts, in which case the blood gene- rally coagulates in the vessel to a considerable ex- tent above the line of sphacelation. This circum- stance prevents the accession of haemorrhage upon the separation of the slough; and the coagulum being subsequently absorbed, the vessel contracts, and is ultimately obliterated. The cause of the formation of this coagulum is by no means evident, although it is probable that the condition of the mortified vessel interrupts the passage of the blood through it, and a coagulum is consequently formed extending to the next important collateral branch. Amputation is sometimes performed a little above the line of separation in which it is unnecessary to tie the arteries, and parts destroyed by sphacela- tion generally separate without the occurrence of haemorrhage, the cavities of the vessels being plugged with coagulum, SECTION IV.
