There still remains some considerable _Phænomena_ to be accounted for, as the convulsive Motions, the prodigious Inflation of the Body, _&c._ As to the former, it may be perhaps accountable from the violent Conflict we may imagine to have happened on the mutual Engagement of the Juice that was found so plentiful in the corrupted Brain, and that which had undergone no Alteration from it’s original Purity. Add to this, that the Animal Spirits in the Nerves receiving some ill Impressions by the Accession of some of those impure Particles, could no longer sally out upon the Command of the Will to any particular Part, but must consequently so irritate the Nerves, as to cause their Extremities to contract themselves; upon which Account the Blood becomes imprisoned in the muscular Fibres, which abridging their Length by enlarging their Diameters, the Parts must necessarily suffer involuntary Contractions: At the same time those minute Capillary Extremities, which terminated in the Miliary Glands, were probably so contracted, or crispt up, as perfectly to close the Orifices of the excretory Ducts of those Glands, which are the only sudatory Pores: By this means all that vast Quantity of Matter which is usually discharged by insensible Transpiration, became imprisoned underneath the Integuments of the Body, and so distended all its Parts to such a prodigious Degree, as was observed. This Constipation of the excretory Ducts, and crisping up of the Extremities of the Nerves, might likewise have a considerable Effect on the small Branches of the Arteries and Veins which accompanied them; for by this means the Blood they contained might be obliged to stagnate in the Glands, which must occasion an Enlargement of the Diameters of those minute Vessels; and so the livid Colour which was extended on several Parts might be probably procured: Besides this, the Blood being in such a comprest State, some of its more fluid Parts might be exprest from it, which lodging underneath the _Cuticula_, might make the Parts appear to be vesicated; there is nothing more certain, than that Animal Bodies perspire after Death; or that the perspirable Matter continues to pass off as long as the Body retains any Warmth. This is confirmed by an Experiment of Sir _Thomas Browne_, in his _Pseudodoxica Epidemica_, where he tells us, That “upon exactly weighing and strangling a Chicken in the Scales, upon an immediate Ponderation he could discover no sensible Difference in Weight; but suffering it to lie 8 or 10 Hours, till it grew perfectly cold, it weighed most sensibly lighter. The like, says our Author, we attempted and verified in Mice, and performed their Trials in Scales that would turn upon the 8th or 10th part of a Grain.” _I am, Sir_, _Yours_, &c. W. B.
