CHAP. III. Instructions and Prescripts for curing certain other sleepy affects, viz. the continual Sleepiness, the Coma, and the Carus.
TO begin with the first; many Authors call this not a Disease, but a drawsie Disposition; for the affected as to other things are well enough, they eat and drink well, they walk abroad, they take care indifferently of their houshold Affairs, but in speaking, or walking, or eating, nay their Mouths being full of Meat, they now and then nod, and unless they are stirred by others, they are presently over∣whelmed with Sleep: and after this manner they Sleep almost a con∣tinual Sleep, not only for some Dayes or Months, but for many years (as it is reported of Epimenides.) Wherefore we judge this Affect by which we are defrauded of more than half of our Life, to be really a Disease and to deserve a cure.
The seat of sleepiness, as of the Lethargy, is to be plac'd in the out∣ward part of the Brain, but with this difference, that the material or conjunct cause of this Disease, tho always pressing at the entrances of the Brain, does not penetrate so deep as it is wont to do in the Lethar∣gy; but affects in a manner only the surface of the Brain, or the meer cortical substances of the Anfractus, the medullary part within being as it were untouched; in which regard it differs not only from the Le∣thargy, but also from the Coma, for in the affect which we describe, tho Sleep be continually pressing, yet it is easily broken off: and more∣over being perfectly awak'd the diseased remember a great many things, discourse with the Friends, being presently ready to fall again into their sleepiness: whence it appears that the cause of the Disease sticks only in the outward border of the Brain, nor does it enter deeply its substance, as in other sleepy affects.
This affect, as I have observed in many, is not very dangerous; for either (as it is often done) it is perfectly cured, or at leastwise conti∣nuing for many years, without a Carus or Apoplexy (which are wont to be feared) it does not presently become mortal or terrible: the re∣lease of this affect often happens upon the change of the seat of the
