If it should be objected, that such Accidents are rare; I answer, that though they are rare, yet they are not impossible; and, what has happened to some, may also be the Fate of others. Though, therefore, the _Falx_ of the _Dura Mater_, and the _Torcular_ of _Herophilus_, the fatal Seat of an _Apoplexy_, are not forthwith so disordered as to yawn by Snuffing, yet the Interests of the Five Senses are but ill consulted, by often drawing from the Brain with Snuff, what we call _Snot_ or _Mucus_, which is evacuated through the Nose; or rather, according to _Galen_, and other Anatomists, through the _Os Ethmoides_, which is the Organ of Smell, but not at all destined for eliminating the Excretions of the Brain. Thus Persons who use Snuff to Excess, instead of bettering, rather impair their Sight, and for their Pains generally lose the Sense of Smelling. As the Person who, for his Crimes, has lost his Ears, is looked upon with Infamy; what better Treatment does he deserve, who, either through a Contempt of Medicine, or an obstinate Fondness to gratify his own Inclinations, either impairs or destroys those Senses, which indulgent Heaven has bestowed upon him for so noble Purposes! With respect to Instances of this Misfortune, and the Reasons why it happens, _Magnenus_ in _Tr. de Abusu Tabaci, Exercitat. 6. Sect. 15._ speaks in the following Manner: "The Sense of Smelling, as I have been told by many, who have either snuffed or smoaked to Excess, is abolished by the Abuse of _Tobacco_, because the mamillary Processes are thereby dried, so that when they are rendered drier than the Effluvia exciting the Perception of any Smell, they cannot be duly acted upon by such Effluvia; for Smell, according to _Aristotle_, in _Lib. 3. de Animal._ consists in the dry Effluvia surpassing the Moisture of these Processes; so that the common Sensory may have a Change produced in it by proper and adequate Objects." _Magnenus_ also, in _Exercitat. 28. Sect. 1._ tells us, "That he knew a Man, who, in one Day, snuffed four Ounces." After which, he proceeds to enquire into the Advantages and Injuries attending the Use of Snuff; and to consider why it excites Sternutation in those who are not accustomed to it, but not in those who are. This accurate Author also, among other Reasons against the excessive Use of Snuff, advances this, that it may enter the Passages of the _Os Ethmoides_, form itself into _Concretions_, and there lodge for a great while. Hence, it is sufficiently obvious, that when the Passages and Perforations of this Bone are obstructed by Snuff, the Air can neither have Access to the Brain for its Ventilation, nor can the Effluvia of odorous Bodies be conveyed to it; in Consequence of which, the Sense of Smelling must necessarily be lost. Though this should, perhaps, be looked upon as a trifling and inconsiderable Loss; yet Snuff, by its highly narcotic, heating, drying, penetrating, and unctuous Qualities, has such an unlucky Influence on the eighth Pair
