“ I have heard it affirm’d by a Gentleman of Reputation, that Pepper-Dust, being powder’d upon the Blossoms of any Tree, will preserve them from Blights, which may be, because Pepper is said to be present Death to every Creature but to Mankind. ”

“ Again, in those warm Months, I find that we have vast Varieties of the smaller kinds of Insects floating in the Air, and it is a thing constant, that every Insect from the greatest to the smallest has its proper Nidus to hatch and perfect it self in, and is led thither by certain Effluvia which arise from that Body which is in a right State for the preservation of it. ”

“ And again, to shew how reasonably we may conjecture that ’tis Insects which thus infect the Trees, let us only consider, that every Insect has its proper Plant, or Tribe of Plants, which it naturally requires for its Nourishment, and will feed upon no other kind whatsoever: Therefore ’tis no wonder to see one particular sort of Tree blighted, when all others escape ”

“ By the foregoing Accounts we may observe, that Mankind, Quadrupedes and Plants seem to be infected in the same manner, by unwholesome Insects; only allowing this Difference, that the same Insect which is poisonous to Man, is not so to other Animals or Plants, and so on the contrary; we observe likewise, that Pepper which is of Use to Mankind, is poisonous to other Creatures, and tho’ a Man cannot eat of the Cicuta, or Hemlock, without prejudice, yet a Cow and some other Animals will eat it to their Advantage ”

“ We may likewise suppose that where these Insects have met with their appointed Nests, they will certainly lay their Eggs there, which the Breath of the diseased Person will fling out in Parcels, as he has occasion to Respire; so that the Infection may be communicated to a stander-by, or else, through their extraordinary smallness, may be convey’d by the Air to some Distance.
It is observable, that all Insects are so much quicker in passing through their several Stages to the state of Perfection, as they are smaller, and the smallest of them are more numerous in their Increase than the others. ”

“ There is room enough to hope, the approaching Cold, which we naturally expect at this Season, may prevent its spreading amongst us for some Months, ’till the Air begins to warm, but the Seeds of that Venom may be brought over in Merchandizes even in the coldest Months, and according to the Nature of Insects will not hatch, or appear to our Prejudice, ’till the hotter Seasons. For to suppose this Malignant Distemper is occasion’d by Vapours only arising from the Earth, is to lay aside our Reason, as I think I have already shewn in my New Improvements of Planting, &c. ”

“ I could mention many Relations we have had, of the Sufferings of the poor People belonging to Marseilles, who to avoid the dismal Consequence of the Plague, have flown for Refuge into the Country, and have either been starv’d to Death, or Murder’d by the Country People; but yet we find, that notwithstanding all these Precautions, [Pg 3] that Pestilence continues to destroy as much as ever, and makes it Advances every Day more towards us. ”

“ Besides, it is my Opinion, that the Winds which blow over so vast a Tract of Land, as these Tartarian Winds must do, that I suppose convey and support the pestiferous Insects, are of so [Pg 33] different a Nature from the Winds coming from the Ocean, that ’tis likely those Creatures which would subsist in the one, would be destroy’d by the other: So that if I am right in this Conjecture, America cannot be subject to the Plague. ”

“ In the Culture of these Aromatick Herbs, such as Rosemary, Lavender, Thyme, &c. we may remark, that they are never destroy’d by any Insect, which may still give us a further Proof of the Antipathy all Insects have to them, for which Reason some People are used to smoak their Houses with these Aromatick Herbs, but especially where the Chambers or Rooms are small and close; and it has been proved, that the Burning of Aromatick Gums and Woods, have likewise been useful in purifying the Air in a House, and preventing the Spreading of Pestilential Distempers. ”

“ We may observe from hence, that the Months July, August, September, and October, the Plague was at the greatest height, and even in those Months, all other Distempers had greater Power over Human Bodies than in the others. ”

“ The Smoaking of Tobacco is helpful to some Constitutions, but was the pure Leaf to be taken directly into the Stomach, it would Purge in a violent Manner, and the Oil of it as I am told is a deadly Poison; however it is to be remarked, that in the time of the last Plague in London, Anno 1665, that Distemper did not reach those who smoak’d Tobacco every Day, but particularly it was judged the best to smoak in a Morning. ”

“ Hence also came that inhumane Custom of shutting up of Houses that are visited with Pestilence, dejecting their Spirits, and consequently making way for the Disease, and taking Men from their Labour, which is a digester of Humours, and a preserver of Health; and if the Disease be Infectious (as in their Opinion it is) it is plain Murder, to shut Men up in an infected and destroying Air.
But all Mens Bodies are not full of Humours; if they were, all would be infected.
After this I find the following Directions to prevent Infection. ”

“ When I consider that the dead Bodies of the miserable People of Marseilles were found full of Insects, and that those Worms could be no way so suddenly killed, as by putting Oil or Lemon Juice upon them, it brings to my Mind several Tryals I have made upon Insects of various Kinds, in order to occasion their speedy Death. ”

“ Thus, it seems, when we suck in Air for Breath, the Lungs takes what is necessary for the Nourishment of our Bodies, and returns back the rest.
After this we may naturally conclude, that where the Rooms, or Houses are small, there ought to be frequent Admissions of the External Air, but especially where those Rooms or Houses are too much crouded with People; and if it is supposed that the External Air is Infectious, the burning of Aromaticks, Gums, or Herbs, upon the letting in of fresh Air, is necessary. ”

“ And why the Plague should not be as well in India, China, the South Parts of Africa and America, as in these Parts of the World? (For I do not find it has ever been in those Places.) This Query gives me a farther Opportunity to suggest, that Insects are the Cause of it, and that they are brought with the Easterly Winds. In the first place, so far as I can learn, there is not naturally in America any one Kind of Creature or Insect that is found in any other Part of the World, and the Plants likewise are all different from those of other Countries ”

“ Bentley, Master of Trinity College, Cambridge; that worthy Gentleman tells me, that the Herb Parietaria, or Peletory of the Wall, is a Sovereign Remedy against the Wevil in Corn or Malt; and according to the Information he has had, an Handful of that Plant being laid here and there in a Granary infected by those Insects, will infallibly destroy them in a Day or two; which Discovery is so useful, that I think it ought to be made as publick as possible, and in this place serves to confirm my Hypothesis, That the Effluvia of some Plants are Destructive to Insects. ”

“ In the Blight of Trees we find, such Insects as are appointed to destroy a Cherry Tree, will not injure a Tree of another Kind, and again, unless the Leaves of some Trees are bruised by Hail, or otherwise Distemper’d, no Insect will invade them; so in Animals it may be, that by ill Diet the Habit of their Body may be so altered, that their very Breath may entice those poisonous Insects to follow their [Pg 18] way, ’till they can lodge themselves in the Stomach of the Animal, and thereby occasion Death. ”

“ The Blights which are attended with large Worms or Caterpillars, seem to be rather hatch’d with the East Wind, than that the Eggs of those Creatures are brought along with it; but those Blights which produce only those small Insects which occasion the curling of the Leaves of Trees, may proceed from Swarms of them, either hatch’d or in the Egg, which are brought with the Wind. ”

“ When I consider this, I cannot help taking Notice, that in those Months we have our chief Fruit Seasons, and when it happens that there has been a Blight in the Spring, or the Summer has not given our Fruit due Maturity, I suppose that the Habit of the Body is so disposed as to receive Infection more readily, than in Years that either afford us little, or else very Ripe Fruit. ”

“ Every Creature, without doubt, requires a different Period of Heat or Cold to enliven it, and put it in Motion, which is prov’d by so many known Instances, that I conceive there is no room for any dispute upon that score. ”

“ It may be asked, perhaps, how these Insects came to destroy the Turneps only, and not touch the other Greens of the Fields, as Cabbages, Carrots, Parsnips, and the like? Every Herb has its peculiar Insect, like the Trees I [Pg 39] have mention’d: Nay more than this, the Insects which Nature hath design’d to prey upon the Flower of a Plant, will not eat the Leaves, or any other Part of the same Plant. ”

“ Some perhaps may object, that the East Wind is too cold to hatch these Creatures; how comes it then that we find them hatch’d when those Winds reign? Or is it reasonable to conjecture that the same degree of Heat is necessary to enliven an Insect as is required to hatch the Egg of a Pullet? The Insects of Norway, Iceland, and such like cold Climes, must certainly have less Heat to produce them, than Creatures of the same Race must necessarily have in those Climates which lye nearer to the Sun. ”

“ In these Experiments, I found that most of the larger Kinds would live some Minutes in Spirit of Wine and other spirituous Liquors, when they were forced into them, and that Oil immediately suffocated them, from whence I suppose, the Air, or Breath they draw, is exceeding fine and subtile, and that a thick Air consists of too gross Parts for them to breath, and that since Oil destroys the larger Kinds of them immediately, the Oleagenous Particles evaporating from such Bodies as Oil, Pitch, Tar, &c. ”

“ The common People in the Country seem to be of my Opinion, that Blights are brought by the East Winds, which they are so well satisfied brings or hatches the Caterpillar, that to prevent the too great Progress of Blights, it [Pg 37] is common for them when the East Winds blow, to provide large Heaps of Weeds, Chaff, and other combustible Matter on the Windside of their Orchards, and set them on Fire, that the Smoak may poison either the Insects or their Eggs, as they are pass’d along. ”

“ Some Farmers imagin’d that the Birds which were there in great Flocks, had eaten the Leaves of their Turneps, and contriv’d all Means possible to destroy them, ’till I convinc’d them that the Birds were rather Friends than Enemies and came there to feed upon the Caterpillars, which were in such great Numbers, that each Turnep-plant had not less than a Thousand upon it ”

“ From the foregoing Observations we may learn, that all Pestilential Distempers, whether in Animals or Plants, are occasion’d by poisonous Insects convey’d from Place to Place by the Air, and that by uncleanly Living and poor Diet, Humane and other Bodies are disposed to receive such Insects into the Stomach and most noble Parts ”

“ The like Plague is said to happen frequently in the Country of the Cossacks or Ukrani, where, in dry Summers, they are infested with swarms of Locusts, driven thither by an East, or South-East Wind, that they darken the Air in the fairest Weather, and devour all the Corn of that Country, laying their Eggs in Autumn, and then dying ”

“ In the dead Bodies of all the Cattle, it was particularly observ’d, that in the Omasus, or Paunch, there was found a hard compact Body, firmly adhering to the Coats of the Ventricle, of a large Bulk, and an intolerable Smell: In other Parts, as in the Brain, Lungs, &c. were several Hydatides, and large Bladders fill’d only with Wind, which being open’d, gave a disagreeable Stink: there were also Ulcers at the Root of the Tongue; and Bladders fill’d with a Serum on the sides of it. ”

“ And how should that be, if they were not either suck’d into the Stomach with the Breath, or taken into it with some unwholesome Food? For they cannot breed in such Bodies from nothing, without either their Eggs or themselves are brought thither by some Accident: For if they were the natural Produce of Animal Bodies, they would then be alike common to all, which we know they are not. ”

“ The good Counsels of our Nation, therefore, to prevent as much as possible the Infection which might be brought among us by Merchandizes coming from Infected Places, have wisely order’d strict Quarentine to be perform’d, before either the Sailors or Goods can be brought ashoar. ”

“ Two Hospitals are prepar’d where they carry all the Sick of the Town, good Orders are daily re-establish’d, and the Obligation is chiefly owing to Monsieur de Langeron, who does Wonders. However, there is not any Divine Service Celebrated, nor are there any Confessors. The People die, and are buried without any Ceremonies of the Church; But the Bishop, with an undaunted Courage, goes thro’ the Streets, and into Publick Places, accompanied with a Jesuit and one Ecclesiastick, to Exhort the Dying, and to give them Absolution ”
