1. Report on the Meteorology oj Scotland Jor the Year ending 

 30th September 1899. By R. C. Mobsman, F.R.S.E., 

 F.R.Met. Soc, Honorary Consulting Meteorologist. 



The following condensed abstract of the meteorolgical condi- 

 tions experienced throughout Scotland during the year under 

 review has been compiled, as formerly, from the observations made 

 twice daily at the sixty-seven stations reporting to the Scottish 

 Meteorological Society. These observations, after being reduced 

 and otherwise corrected by Dr Buchan, are published as an 

 Appendix to the Quarterly Returns of the Registrar-General for 

 Scotland. The monthly and other reports issued by the London 

 Meteorological Office have also been utilised. It may be re- 

 marked that comparatively few of the stations are provided 

 with sunshine recorders, so that the remarks on this element of 

 climate are not based on such reliable data, as in the case of 

 temperature and rainfall. 



October 1898. — The weather of October was generally fair and 

 dry till the middle of the month, but from the 14th to the 19th 

 very heavy rains were experienced, unsettled weather prevailing 

 until the close of the month. Temperature was exceptionally 

 high in the north from the 2nd to the 6th, rising to 79° *8 on the 

 3rd at Lairg, and to 78° -7 at Dumfries. The mean temperature 

 was 50° '1, or 3°*7 above the average, being the highest yet 

 recorded by the Scottish Meteorological Society for any October. 

 The highest mean temperature was 52°-0, at Craigrannoch, 

 Greenock, and Dumfries, and the lowest, 46° -4 at Braemar. The 

 general distribution was in close agreement with the normal, the 

 excess being, if anything, a little higher at inland than at coast 

 stations. The mean rainfall was slightly above the average, 

 taking the country as a whole, but, as is usually the case, was 

 distributed in a very irregular manner. The excess was very 

 large at Haddington, Smeaton, and at Broomlands near Kelso. 

 On the other hand, there was a considerable deficit in many 

 districts, especially from Cape Wrath to Islay, where but half the 

 normal quantity fell. Bright sunshine was below the average in
