The winter of this year was more severe than usual in this country, and much less rain in March and April than is customary at that season.
About the end of April the weather became very warm, and continued so till the 20th of May; from which time, till the 22d of June, it grew rather cool for the season of the year, the air being refreshed by strong westerly breezes.
The 22d of June, the wind changed to north-west, and was very moderate; upon which the weather became exceeding hot, and continued so all that month, and for the first ten days in July. The remainder of the summer was such as is common in this country, without any of the hot easterly winds.
On the 25th of September the first rains fell, and continued only one day; after which the weather was extremely pleasant till the end of October; when the second rains fell, and continued a few days. Upon their ceasing, it set in fair and serene till the 14th of December; when a small shock of an earthquake was felt, and a hard frost began, which continued all that month.
For want of proper instruments, the changes of heat and cold this year are here represented according to what they appeared to our senses.
From the beginning of January till the middle, a great deal of snow fell, the frost continued, and the air was exceeding cold; the thermometer being but once above 40 in the evening, and in the morning commonly 36, once 34, on the third at 9, A. M. A few days of fair, pleasant weather succeeded this cold, and then began violent rains, which continued during the remainder of the month.
The rains were almost constant till the 20th of February; the latter part of which month was fair, pleasant weather.
March set in with variable spring-weather, (though somewhat cooler than usual), which continued till the 23d; from which time till the end a great quantity of rain, hail, and thunder.
April was fair (except one thunder-shower) till the 19th; during which the weather was pretty warm, with a sort of haziness in the air. The 20th and 21st, it blew very hard from the south-west, with much rain, and the weather became unusually cool for the season. The mercury in the thermometer, which had before commonly rose to 74 in the afternoon, seldom afterwards getting up so high as 66 during the whole month, which was attended with a good deal of rain and thunder, some hail, and the wind generally fresh westerly.
May (except on the 13th and 23d, when some severe thunder-showers fell) was fair, pleasant weather, and much cooler than usual. The thermometer was unfortunately broke this month; so that from this time till May following, the observations were made by a large thermometer, filled with spirits, which showed distinctly the changes of heat and cold, but was not upon any known scale.
The beginning of June was fair and cool weather for the season. On the 10th it began to be hot; and, notwithstanding strong westerly winds, and often flying clouds, the air was very hot during the rest of the month. On the 12th, at 8 P. M. were felt two small shocks of an earthquake. The sky was at that time serene, and it blew fresh.
On the night between the 1st and 2d of July, some severe thunder-showers fell; a thing very extraordinary at this season. During the whole of the month, the westerly wind blew fresh, and generally continued great part of the night, by which means the air was rendered remarkably cool.
This chill weather continued a few days in August; but the remainder of that month, the winds, though westerly, being moderate, and ceasing a little after sunset, together with its succeeding such cool weather, made it seem uncommonly warm, though from the thermometer it appeared that the heat was not in reality greater than in other years. On the 19th, at half an hour after eleven o’clock at night, was felt a small shock of an earthquake. The sky was at that time serene, and little wind stirring.
The beginning of September was hot, as in August; but on the 10th it became sultry, particularly in the night, and continued so till the 18th at night, when the first rains began to fall; and though they were but moderate, they rendered the remainder of the month quite cool.
Though it rained a little on the 8th of October, and continued cloudy for several days; yet the second rains did not, properly speaking, fall till the 23d, when they were plentiful, and continued three days. The remainder of that month, and all the rest of the year, afforded nothing remarkable.
The snow which fell on the 5th of January lay six inches deep, and continued for several days in places shaded from the sun; which is not usual in this country; the quantity that fell in this month was likewise somewhat extraordinary.
February and March had nothing in them different from other years.
April was more rainy than customary. On the 28th, at half an hour after one in the morning, were two pretty brisk shocks of an earthquake, and at six in the evening another.
May and July were as usual in a moderate summer; but June had more northerly winds, and was hotter than common; the usual height of the thermometer being 95.
From the first week in August, several days of easterly winds rendered the air unusually hot, which by a very singular, though but small, shower of rain on the 30th, was cooled for a few days; the thermometer, P. M. falling from 92 to 83.
The first rains were ushered in by the accustomed squall of wind on the 4th of September at night, and were violent for a few hours, but did not cool the air. On the 20th and 22d, one shower of rain fell, and rendered it more cool; and the plentiful rain on the evening of the 23d, and greatest part of the day on the 24th, completed it.
On the 16th of October, at night, the second rains fell, with a good deal of thunder, and on the 19th some more; after which the rest of the year afforded nothing that was remarkable.
This year had nothing uncommon in the weather till the 12th of March, when it became cold; and an unusual frost, with, a north-east wind for a few days, nipped most of the blossoms on the trees; the mercury in the thermometer after noon being rarely above 54, whereas before it was at 62.
April was remarkably dry, having but one shower of rain, on the 6th. May and June had nothing extraordinary.
July, except a few days at the latter end, and all August, not being refreshed with the westerly breezes, and having several days of easterly wind, particularly the middle of August, were extremely hot; the afternoons height of the thermometer being often 100, and twice 101.
The first rains were very moderate, and fell on the 10th September, being as usual preceded by a squal of wind. The second rains fell heavy and seasonable, about the middle of October; from which time happened nothing singular all the rest of the year.
The 4th, 5th, and 6th of January this year, it snowed almost continually; so that it lay in the streets above a foot thick, which is very uncommon. It was not all thaw’d in the city for some days; and in such places abroad where the sun-beams did not reach, there was still some lying on the 13th. From this time till June the weather was as usual.
It began to blow very hard westerly on the 13th June, and the wind brought along with it many clouds, which let fall two small showers of rain on the 14th, one at 10 A. M. the other at 7 P. M. which sunk the mercury in the thermometer from 84, its usual afternoon’s height, to 76 three fourths.
August had none of the usual cloudy weather; yet the rest of the summer had nothing in it particular.
Though it began to be cloudy on the 4th of September, and continued so for a few days, and even thundered; yet no rain fell till the 11th in the afternoon, and then only a gentle shower of about an hour, which sunk the thermometer from 82 and an half, its common afternoon’s height, to 77. It soon however rose again; and the wind being easterly or northerly from the 20th to the end of the month, the weather was unusually warm; the afternoon height of the mercury being 85 or 86.
In the month of October there fell but one shower of rain, the 25th P. M. so that the thermometer kept high all the month, and the weather was extremely pleasant.
On the 2d and 3d of November the rains fell plentifully; and, through the whole of this and the succeeding month, more fell than is usual in other years. There did not happen either frost or snow.
From the beginning of January till the end of March, the winds were much higher than usual at that season, neither was there any frost or snow; but more rain fell in January and February than is common, and the weather in general was bleak and unpleasant. The rest of the year till September was mild, and very moderate.
Though it was cloudy, and threatened rain about the 20th of September, yet none fell in this month at Aleppo; so the thermometer’s evenings height kept up at 82 till the end of the month.
The whole of October was clear and settled weather, except one thunder-shower on the 13th, (which sunk the mercury in the thermometer from 81 to 73) a small shower on the 22d, and a gentle rain the whole of the 24th.
On the 7th of November the rains began to fall plentifully, the weather became as in other years, but there was no frost in this month.
December was rather more foggy than common, without either frost or snow.
Being, for want of leisure, prevented from giving a particular account of the epidemic diseases from 1748 to 1751, that of the weather is also omitted.
The change of stile from the Julian to the Gregorian rendering references to the general account of the weather, which were made according to the Julian calendar, indistinct, I conceived it necessary to give the weather of the years 1752 and 1753 compleat.
It is true that the short method formerly used might have served till September, as the act of parliament did not take place till the 3d of that month: but, besides the want of uniformity that would have attended a change in the method before the year was out, I thought, that, if there were any who should make an objection to the former, this would make them some atonement; and that it could be disagreeable to none, more especially as the epidemic fevers of those two years changed their appearances so remarkably according to the season.
The thermometer used, till noted otherwise, was the large one, and the situation during the whole two years in the wooden kiosk. Where-ever a rainy day occurs, with one ′, it is to be understood that a small shower or two happened on that day; ‴ denotes violent rains, and ″ an intermediate degree of rain.
The first week of this month cloudy and rainy; from the 8th to the 29th continued clear, fair weather, with some light clouds now and then intervening.

In the first fortnight, the mercury in the thermometer never rose above 50. Through the whole month, the most general height at nine in the morning was 46, from which time it usually rose 3 or 4 degrees; so that at 3 P. M. it stood at 49 or 50, except in rainy weather, when the variation was less considerable, and there was frequently none at all.
Light clouds were more frequent in this month than in the former; the weather in the afternoon often became overcast; the three last days serene; the rain fell mostly in the night, and in violent showers.
