Exsanguination incapacitate swine, poultry and domestic sheep, whereas a chemical is used for injured livestock. Continued pumping operation of the heart during exsanguination increases the rate of depletion, and thus hastens death, by raising the fluid pressure of the blood. Because the heart operates like a positive displacement pump, reduction of blood volume will not affect efficiency of cardiac output—deprivation of blood to the heart does gradually result in diminished function, but concurrently with similar death of other parts in the body. Quickly after the animal is incapacitated it is hung upside down by its hind limbs and an extremely sharp
Baconian method doctrinal diversity compared to the continent. However Matthews is quite outspoken, that "Bacon's entire understanding of what we call “science,” and what he called “natural philosophy,” was fashioned around the basic tenets of his belief system." The method consists of procedures for isolating and further investigating the "form nature", or cause, of a phenomenon, including the method of agreement, method of difference, and method of concomitant variation. Bacon suggests that you draw up a list of all things in which the phenomenon you are trying to explain occurs, as well as a list of things in which it does not
