Mr. R. H. Scott. 



The following may be considered as a summarised statement of the 

 scientific work done at the Kew Observatory since its foundation as a 

 Physical Observatory : — 



1. Improvements in the construction and manufacture of instru- 



ments for meteorological observations, the production of new 

 ones, and the modification of older forms. 



2. The same with regard to magnetic and electrical instruments. 



3. The distribution of such instruments over the globe. 



4 The ensuring of accuracy of observations by means of the 

 verification and distribution of standard instruments and the 

 instruction of observers. 



5. The continuous recording of magnetical and meteorological 



phenomena. 



6. The practical adaptation of photography to scientific purposes, 



and especially to the continuous registration of phenomena 

 occurring On the sun's surface. 



7. The improvements of nautical, geographical, fiscal, physical, 



and medical instruments by verification, and of horological 

 by watch-rating. 



8. Assistance in the prosecution of research in the following 



sciences : — 



1. Astronomy. — De la Rue's, Stewart's, and Loewy's solar 



researches ; Gassiot's spectroscopy. 



2. Geodesy. — Pendulum observations — Basevi, Heavisidp, 



Peirce, Herschel. 



3. Magnetism. — Sabine and others too numerous to mention. 



4. Meteorology. — Ditto, ditto. 



5. Physics. — Roscoe's Actinometry ; Stewart's ditto. 



Sanitary Institution — Ventilation. 

 Greaves, Evaporation. 



Stewart, Dilatation of Air and Theory of Ex- 

 change Experiments. 

 Stokes, Friction of Gases. 

 Loewy, Pressure on Thermometers. 

 Anemometrical Coefficients, &c. 



6. Magnetic Surveys — Scotch (Welsh) ; Arctic and Ant- 



arctic — Perry's, Thorpe's, &c. ; Fort Rae and other 

 Expeditions.
