Paper, 'On rigor mortis in fish, and its relation to putrefaction' by J [James Cossar] Ewart

Description

Ewart writes: 'It has been long recognised that rigor varies extremely not only in the time of its appearance, but also in its intensity. It may be well marked and resemble closely a spasm, or so indistinct that it is better compared to a stiffening than to a contraction of the muscles. So much is this the case that it might be convenient to describe rigor as accompanied with contraction in some cases and with stiffening in others. I have often noticed that when rigor comes on immediately after the loss of muscular irritability, it looks extremely like contraction; but when it is postponed for days, by lowering the temperature or otherwise, it more closely resembles coagulation.'
