Remarks on position, &c. 



c-2 



tlie coach house ; about G ft. of pipe 

 conducts the rain into a bottle placed 

 in an accessible position. This gauge 

 is .30 ft. from No. 84. 



About 1*00 ft. from No. 84. In a good- 

 sized garden, rather sheltered by 

 some peas, which were removed, and 

 a promise was given tliat nothing 

 sliould shelter it again. 



Rises about a foot above flat roof of 

 observatory; funnel taicen down, 

 restored to a truly circular figure, 

 and a correct glass supplied. 



Gauge so constructed that true dia- 

 meters could not be taken ; position 

 very unfavourable; fastened on a 

 wall, and with a very fine liolly tree 

 6 ft. above the gauge and not 3 ft. 

 from it. It was immediately cut 

 down. 



On a raised part of the roof, near its 

 centre, and perhaps 20 ft. from the 

 nearest side. 



Very old and roughly made, much 

 sheltered by trees, esjieciaUy by a 

 wall-like row of lofty poplars. 



In the hollow stump 'of a tree, weU 

 exposed in every direction exceptE,, 

 where some laurels were growing 

 too high. Mr. Heberden promised 

 to have them cut. 



On lawn in an open position ; ground 

 level for some distance round the 

 gauge, but it falls to a lower level 

 about 100 yarcb to the S. 



On roof, water conveyed by pipe into 

 ground floor ; experiments often re- 

 peated show that the loss in passing 

 through this length of pipe is almost 

 inappreciable. 



By permission of the oflicer in com- 

 mand of the garrison tliis gauge was 

 placed on the summit of the keep, 

 the highest point of the Castle, and 

 regimentiil orders issued for its 

 proteetiou by the bombardiers on 

 duty. 



Funnel made by a local workman as 

 " exactly 5 inches !" A new funnel 

 503 in. in diameter, was sent to re-
