HE inventor obferving that all waterengines require a vaft deal of expence to be A kept in repair, had fudied to invent an engine which might be ufeful, not expen five, and yet lafting; and has been fo happy as to find out an engine of particular qualities, which would carry the water as high and as far as any other engine could do, without ever moving.

B

He thinks it his duty to inform the public of the ufe and effect of this newinvented engine; but nobody can blame him for keeping fecret the conftruction of it, till proper opportunity fhould re- C quire the publifhing of the whole ftruc ture. His engine is fet on working by a water-fall, fo that one part of the water that falls down, will carry up the other part of the water as high as you pleafe, and in fuch quantities as you think proper, and as much as the affluence of the D water will afford. Suppofe a spring which has a fall, and fufficient room where the engine can fland, the water of that fpring thall be carried to feveral places of a town, lying upon a hill, and higher than the Tpring. One part of the water that falls down will carry E up the other water, and force it to all thofe places where it is wanted, without the lealt motion or movement of the engine. And it is to be obferved, 14 That the quantity of water which is carried up, is never lefs than the quantity which falls down; altho the affluence of the water fhould diminith, yet the afcending water will never be lefs than the falling water. 2. By the help of the machine the water may be carried. to different degrees, one quantity higher, the other lower, and conveyed over hids

F

and through vallies, as far as neceffity requires it. 3. The engine is lafting, because there is no motion, which might wear its parts. 4. In cafe a water-fall fhould be wanting, one can make ufe of another machine, which will fupply the water-fall. The inventor affures, that he will convince every one, who will please to apply to him, of the pertain effect, by experimental and infalli ble mathematical demonftrations. He has a little model, which carries the water of feet higher than where the fall begins, and the fall is but 34 feet.

The weather at the end of the last month was frofty, clear, and cold ; at the beginning, of this, it became more moderate, grew cold and wet towards the middle, and again cleared up towards the conclufion, with fome fudden guts of wind, and rain, and hail. But in general the weather, during this month, may be faid to have been remarkably even, and from its fenfible qualities not likely to give birth to any particular distemper.

The Small Pox continued to be the principal epidemic during this period, as it had been in the preceding months; during which time it attack'd moft of choic who had. not hitherto had the diftemper, and is now fpread into the fuburbs, and the neighbouring villages, but ill in a favourable way in general. Some have the confluent, a few te bleeding kind; but thefe are not common, confidering the num

those who are feiz'd with it. After bleeding where it was indicated, and cleanfing the ftomach with an emetic at the first attack, mild cardiacs, with small dofes of anodynes, fucceeded much better than the cooling antiphlogistic regimen, which commonly occafion'd languors, increased a troublesome, unavailing ptyalifm, and retarded the eruption, and progrefs of maturation.

Several were feiz'd with a remittent fever,accompanied with acute headachs, reftleffnefs, and anxiety, a quick, full pulfe, without much thirst, which generally foon gave way to bleeding, emptying the first paffages, and gentle diapho

retics.

the seasons, and the principal changes of
it taken notice of. Tho' the advantages C
refulting from them may yet be but
Imall, a longer feries may prove more
fruitful. To the writer it appears that
not only a steady courfe of any kind of
weather may produce particular difeafes,
but likewife very quick transitions from
one extreme to another may be equally
injurious; with this view he has noted D
not only the greateft afcent and defcent
of the quickfilver in his inftruments, but
likewife the greatest variations that have
happen'd in the space of 24 hours, in a-
ny part of the month; and thefe circum-
ftances he has placed as follows:

than can be equalled in every refpect by any country in Europe, of which we have any authentic memorials, as may perhaps on fome future occafion be demonstrated. From the preceding table it will appear, that during the last 12 months the Mercury in the Barometer never rofe higher than 30 inches, 6 tenths; never fubfided lower than 29°; confequently, that its motion did not much exceed inch in that time, nor more than 6 tenths of an inch in 24 hours.

The Thermometer likewife discovers a more equal temperature, with respect to heat and cold, than might have been expected in a country where so many exclamations are daily vented against the inconftancy of the weather, and the irregularity of the feafons: The utmost afcent of the quickfilver was 68 degrees, the loweft defcent 37 degrees; fo that it only traverfed in the feveral changes from spring to fummer, from both to autumn and winter, about 32 degrees, and not more than 8 of these in 24 hours at any one time.

If we, therefore, compare this account with the most accurate we have of the weather in any other country, we fhall perhaps find abundant cause to be fatif fied with our own, in this, as well as in moft other respects.

T was juftly obferved upon the publication of fome pieces intended to aggravate the crime which was fuppofed to have been perpetrated by Mifs Blandy, (fee p. 114.) that they were not only abfurd but unjust, because they had a direct and powerful tendency to remove that difpaffionate neutrality with which a jury fhould hear evidence in a tryal for life; an obfervation equally pertinent, with refpect to thofe laboured harangues with which the counfel G for the crown on thefe occasions endeavour to display their own eloquence and the prifoner's guilt; for though, as the hon. Mr Legge obferves, in his excellent fummary of the evidence, in proportion to the enormity of the crime, hould be the ftrength of that evidence upon the credit of which it is imputed, Hyet the effect is just contrary; the zeal to punifh is always increafed by the enormity of the offence, and a less degree of evidence determines a jury a
