Marshall, who touches very slightly on the subject, says, "The flesh of sheep when slaughtered is well known to be of various qualities: some is composed of large coarse grains, interspersed with wide empty pores, like a sponge; others of large grains, with wide pores filled with fat; others of fine close grains with smaller pores filled with fat; and a fourth of close grains without any mixture of fatness. The flesh of sheep when dressed is equally well known to possess a variety of qualities: some mutton is coarse, dry, and insipid,--a dry sponge affording little or no gravy of any colour. Another sort is somewhat firmer, imparting a light-coloured gravy only. A third plump, short, and palatable, affording a mixture of white and red gravy. A fourth likewise plump, and well-flavoured, but discharging red gravy only, and this in various quantities. It is likewise observable that some mutton, when dressed, appears covered with a thick, tough, parchment-like integument; others with a membrane comparatively fine and flexible." This membrane ought to be rather thin than thick, as, when of the latter texture, you may safely affirm that the animal was aged. _Looseness_ is reckoned a bad quality of the flesh of sheep during life, as indicating a coarse-grained porous mutton, and as equally exceptionable with that of _hardness_: while _mellowness_, and firmness, are much to be desired, as forming a happy mixture, deemed by some the point of perfection. The tendency to become fat at an early age, though a valuable one in some points, is not so in others. Premature decay is always the result, showing with certainty that a healthy action has not been going on. An animal when _loaded_ with fat cannot be looked upon otherwise than as in a diseased state, and liable to embarassment of many organs, especially of the heart and brain. Sudden death on any hurried exertion is far from rare, and life, from the difficulty of enjoying it, is any thing but desirable.
