Determinations of the value of the electrical resistance of living things ware made by many authors, but there are unexpectedly few reports about that of the muscle as the part of living things. We investigated the timely change of the electrical resistance in muscle under various conditions of heating, cooling and electrifying. We obtained the following results
(1) The fish belongs to the secondary conductor.
(2) The value of electrical resistance of fish varies according to the kind of fish.
(3) The electrical resistance of fish changes with time and relates to the putrefaction. So its electrical resistance may be good indicator for the judgement of freshness.
(4) The electrical resistance decreases by heating or electrifying. We think that the current increases gradually by the electrical shcck according to the upper reason.
(5) The electrical resistance changes by cooling with a similar tendency as by heating. We think the cooling of fish affects its taste.
