 and sunset ; but I soon found that, do what I would, the in- 

 struments remaining stationary were inevitably influenced hy 

 the sun, either immediately or by reflection. In an open turret, 

 simply tiled as ours are, the effect was the same ; and during 

 at least eight months in the year, the sun was so vertical that 

 perfect shade in the same spot could not be maintained through-
