The instruments with which the foregoing observations were made are the same that were used in former observations of this kind, a full account of which was given by Henry Cavendish, F.R.S. in the LXVIth Volume of the Philosophical Transactions; but as they have been moved from the situations they had at that time, it may not be amiss to mention how they are placed now, in order the better to shew what degree of accuracy may be expected from them. There being no one situation for a thermometer out of doors so good as could be wished, it became necessary to make use of two thermometers; each is placed out of a three-pair-of-stairs window, one facing E.N.E. and the other W.S.W. and they stand about two or three inches from the wall, that they may be the more exposed to the air, and the less affected by the heat and cold of the house. As the sun shines on the eastern part of the building in the morning, the thermometer to the westward is made use of for the morning observation during that season of the year when the sun rises high enough to affect the other; for all other observations, that to the eastward is employed. Neither the building opposite, nor that on the south side of the thermometer to the east, are elevated above it in an angle of more than $13^\circ$; but the opposite building is not more than twenty-five feet distant. The thermometer to the westward will not be affected by any other building than one to the northward, which is elevated above it in an angle of $20^\circ$, and which is only twenty feet distant. Vol. LXXVIII. The thermometer within doors is placed close to the barometer, the heights of which it is intended chiefly to correct; the windows of the room in which they are kept look to the westward, and in winter the room has constantly a fire in it. The vessel which receives the rain is fixed to a chimney at the top of the house, and rises six inches above the chimney; it is not screened from the rain by any building or chimnies, there being none higher than that to which it is fixed.
