90 REPORT—1905. 
. Lopographical Situation.—The Observatory is situated on a hilltop, whose height 
above the environs is 10 metres. The dip (mean) is 7°. 
Geological Structure.— The instrument is mounted on a pillar built on the same 
rock, which is a calcareous one, whose thickness is very variable.! 
The station is an astronomical observatory.

Shide, Newport, Isle of Wight, England. 
Lat., 50° 41’ 18’’ N.; long., 1° 17’ 10’ W.; alt., about 50 feet. 
Foundation is on a brick column, 18 inches square and 6 feet in height, founded 
upon disintegrated chalk, beneath which there is solid chalk. 
Topographical Situation.—On the eastern side of a valley running north and 
south. The station is 40 feet above a small stream in the bottom of the valley and 
200 feet below the crest of a ridge which runs E.s8.E. to W.N.W., across which the 
valley is cut. In the bottom of the valley, which is about half a mile in breadth, 
there is alluvium and grass land. Its eastern side is steep (about 25°) and covered 
with grass and gorse. 
Geological Structure.—The station is on the chalk ridge which forms the back- 
bone of the island. The dip is steep, approaching the vertical, and towards the 
north. ‘The strike is as given above.” 
Time-keeping.—Time is obtained from the post-office at Newport, which receives 
a daily signal from Greenwich. It can also be obtained by noting the time when 
the sun is due south. For this purpose, in the south wall of the Observatory there is 
a vertical slit made of two sheets of iron. The image of this is thrown by the sun 
on to a north wall 16 feet distant. When this image reaches a line on the wall the 
sun is due south. Accuracy +1 sec.

Strassburg, Elsass, Germany. 
Lat., 48° 35’ N.; long., 7° 46’ 10”’ E.; alt., 185 metres. 
Foundation is on compact pure gravel, alluvium. 
Topographical Sitwation.—The instrument is on an isolated pier in water-bearing 
strata, on the Rhine plain, in the University Garden, 60 metres from Goethestrasse 
and 65 metres from the Universititsstrasse, along which heavy traffic is not per- 
mitted. The Vosges Mountains are about 20 kilometres distant and the Schwarz 
Wald about 15 kilometres. 
Geological Structure —On the compact gravel of unknown depth which fills the 
valley between the above-mentioned ranges. Water-bearing strata are found at a 
depth of 1°50 metre. 
Time-heeping.—Time is kept by means of a Strasser and Rohdesche ‘ Normal 
Uhr’ (chronometer), in telegraphic connection with the Astronomical Observatory. | 
Weekly, or more frequently, if required, this is compared.

Lat., 33° 51’ 41'’; long., 10h. 4m. 50°81s. E.; alt., 142 feet. 
Foundation is on clay and ironstone shale on sandstone. The seismograph is 
placed on a glazed brick pedestal about 3 feet from floor, as per instructions sent 
with the instrument. 
Topographical Situation—On top of a hill 142 feet above sea-level. Gradual 
slope south and east side, precipitous on north and west side. uy 
The station is an astronomical observatory.
