244 On the Severe Cold of last Winter, <SfC. 



2 m. 40' 81°.3 Circumstances the same. N.E. exposure, only 791 °— 



2 h 14' 79§. 2 h 25' 804. Ex- 

 posed to the E. at a distance 

 from the wall, and a white 

 9 a East exposure 50°. Ditto, ditto, paper shade against reflec- 

 tion, from a flat roof near, 

 2 h 40' 82°.— Ditto, 3 h 6' 

 (well-shaded) 8l|. 3 h 12' 

 81i°. 

 June 25th, 904 m. 77°.2 Circumstances as ahove. 



804 a. 82 East wall. Other thermometer well shaded in 

 9 a. 71. Ditto. trees, at 3 h 50', exactly 80°. 



On the 26th a very intense temperature occurred, and as 

 my observations were made in a peculiarly cautious manner, 

 and with the greatest attention to every possibility of reflec- 

 tion, I have no scruple that they should be made public. 



June 26th. 

 9 m. 75°.4 Adie's at a N. window, as last page 

 12 h 56' 81 l h 0' pother therm, exposed behind a shady hedge, 804°. j 

 l h 35' in the sun 110° 



l h 38 at the house 83-°3. Brought out Adie's, and hung it behind a very 



large stem of a tree, perfectly screened from 

 the sun by high trees, &c. 

 l h 45 (Knie's) 82° hung behind a fragment of building, with an im- 

 mense head of ivy, and thoroughly shaded. Not far 

 from Adie's. 

 In the sun 111 

 2 h 0' Sun 113° Knie's 824° Adie's 82.5 



2.20' — 1144° 82f fully 82.9 



2. 30' 1144° 834 83.3 



2. 45' — ■ 113° — — 84| 84.0 Finding that Knie's was $° 



above Adie's, probably arising from the sun's 

 reflection, which was on the grass 20 feet off, 

 I now moved it to quite a different place. 

 3.0' Sun 114° Knie (New Place) 844° Adie 84°.3 



3.12' — 112° 84.1 



3.17 82| 84.0 



Finding Adie's li° highest, I brought Knie's beside it, 

 and found them at 

 3.30' Sun 112 Knie's (beside Adie) 82f°, Adie 84°.0, or just the same 

 as before. Now, I should state, that Adie's was in 

 his sympiesometer case, which probably kept it too 

 hot by producing a reflection of the heat from the 

 surrounding brass, after long exposure. 

 At 10 h a. at the house, E. window 72°.
