Cure for the dogmatical incurables, performed in matter of fact by N. Merry philo-chym. All subjects have their excrements in them, and excrements will make but bad medicines. First cure the subjects of their diseases, and thou shalt happily cure the patients of their sicknesses. All true medicine is the incorruptible and undigestible part latent in their subjects. Whence it follows that excrements and foods are no physick, or very improper medicines; hence a necessity of seperation.
