THE CONCLUSION.

THUS much for the Anatomy of the Brain and Cerebel, and of their Appendix, both Me∣dullar and Nervous, and of the Uses and Offices of all the several parts, of which we have largely treated. There yet remains, after we have viewed, not only the outward Courts and Porches of this Fabrick, as it were of a certain Kingly Palace, but also its intimate Re∣cesses and private Chambers, that we next inquire into, what the Lady or Inhibitant of this Princely place may be, in what part she doth chiefly reside, and by what Rule and Government she disposes and orders her Family. Then we ought to take notice, what defects and irregularities happen to it, or to its parts and powers; then to what injuries of changes or Diseases this Building or House, to wit, the Brain and nervous Stock, may be obnoxious. For indeed I am as it were bound, by reason of the Work it self, and the promise I made before, that for the Crown of the Work, a certain Theory of the Soul of Brutes should be added after the naked Anatomical Observations and Histories of Living Crea∣tures, and of their animated Parts. Truly it is but just and equal, that we enter upon this Discourse of the Soul, and that other task of Pathologie, to wit, that the Asperities and hard sense of our already instituted Anatomy may be sweetned with those kind of more pleasant Speculations, as it were cloathing the Skeleton with flesh; and that the Reader being wearied by a long and troublesom Journey, may be a little refreshed and recreated. For in truth, whatsoever of our Work is performed without form or beauty, may seem as the Foundation of a Building only placed on the Ground, in which no elegancy or neatness doth shine, but that all things appear rude, and as yet built of rough and unpolished stones. A Superstructure indeed may be promised to be put upon this Foundation, perhaps fair and beautiful, whereby the minds of the Beholders, may be pleased and instructed. But truly this kind of work may be too hard and great to be performed by our weakness: neither doth it become me to proceed in my undertakings, before these have undergone the Censure and chance to which they are subject. For I fear, lest this Foundation, but now laid, should become too weak and feeble for the sustaining an higher Fabrick, at least until this hath for some time undergone the tryal, by lying open to winds and storms.
