BUT, and if the NAVEL continues _Ulcer’d_ after the falling of the STRING from it; in that _Case_ proper _Desiccative_ and _Astringent Medicines_ are to be apply’d, such as small _Rags_ dipp’d in _Lime-Water_, but not too strong; or in _Plantane-Water_, wherein a little ALUM has been dissolved. If the ULCER be but small, a _Pledget_ of _Dry Lint_ will be sufficient; observing always to keep a good _Linnen Compress_ on the _Top_ of whatsoever _Remedy_ is us’d, with a SWATH to keep all fast, until the NAVEL be perfectly heal’d and _cicatriz’d_; lest at the same time it should also force itself _outwards_, as in the ’foregoing _Case_. V. THE _Child_ is also very frequently troubled with the APHTHÆ, or _Ulcers of the Mouth_; commonly call’d the THRUSH: Proceeding either from vitious _Milk_, or from its _Corruption_, in the STOMACH; emitting sharp _Vapours_, which readily affect the tender Skin and Superfice of the INFANT’S _Mouth_, and _that_ the more easily, because the same _Tunick_, or _Skin_, which invests the _Mouth_, is common to the _Gullet_, which naturally communicates the _Affections_ of the VENTRICLE to the _Jaws_. Hence it is that the _Nice Taste_ of the _delicate_ TONGUE so readily distinguishes all _Relishes_; and hence it is that the Ingenious _Physician_, by looking upon the TONGUE only, is able to judge of the prevailing _Intemperament_ of the whole Body. THE _Cure_ of these THRUSHES, proceeding as aforesaid from the _acid Vapours_ of bad MILK, or from its ill _Digestion_, depends properly and entirely upon defeating and obtunding the ACRIMONY, by _proper Absorbents_, and gentle _Purgatives_. VI. ANOTHER _Symptom_ not only familiar, but even _Natural_, to all CHILDREN, is their _Teething_; which tho’ _This_ be the mere Work of NATURE, yet because of the various _Distempers_ and _Symptoms_, which commonly attend and conjoin this DENTITION, it is not improperly reckon’d in the CATEGORY of the _Diseases_ of INFANTS: Which however is to be understood, not of the _Simple_ DENTITION, but of the difficult _Breeding of Teeth_; Not but that the CHILD is furnished with _Teeth_ even before BIRTH, tho’ they lurk so long in their proper _Sockets_, being cover’d with the GUMS, until their due Time of _Eruption_[189]. Tho’ in the _Interim_, it has been observed that some CHILDREN have brought eminent TEETH with them into the World[190], as it is also for _Instance_, particularly reported of LEWIS the XIV of _France_.
