Common too, to all these animals, is marrow; a substance which in all cases is possessed of certain emollient, expletive, desiccative, and calorific properties. The most highly esteemed of all is deer's marrow, the next best being that of the calf, and then that of the goat, both male and female. These substances are prepared before autumn, by washing them in a fresh state, and drying them in the shade; after which they are passed through a sieve, and then strained through linen, and put by in earthen pots for keeping, in a cool spot.
