 The months from November to February are coloured blue ; from March 

 to May, green ; from June to August, red ; and September and October, 

 black. Prepared by Alexander Buchan, Secretary. 



2917. Charts, showing the mean monthly and annual amount 

 of the diurnal oscillation of the barometer over the globe, from the 

 a.m. maximum to the p.m. minimum, by lines of 10, 20, 40, 60, 80, 

 and 100 (and upwards) thousandths of an inch (O'OIO, 6-020 

 inches, &c.). Scottish Meteorological Society. 



The portions shaded red indicate an oscillation of O'lOO inch and upwards. 

 Prepared by Alexander Buchan, Esq., F.K.S.E., Secretary of the Society,

2918. Charts, showing by isobaric lines the mean pressure of 

 the atmosphere, and by arrows the prevailing winds over the globe 

 for each month. Scottish Meteorological Society. 



Isobarics of 30 inches and upwards are coloured red, and those under 

 30 inches blue. Thus the red isobarics indicate where pressure is in excess, 

 and the blue isobarics where the pressure is in defect. 



Calms are marked with a circle, and variable winds with an asterisk. The 

 arrows fly with the wind.

2919. Diagrams, showing for London the influence of weather 

 on mortality from different diseases and at different ages. No. I. 



Scottish Meteorological Society. 



Mortality classed according to 



A. Age (average of 5 years). Under 5 years coloured red; 5 to 40, 

 blue ; 40 and upwards, black. 



B. Sex (average of 30 years). Males coloured red ; females, blue. The 

 weekly deviations from the mean line are given in per-centages above and 

 below the average. 



C. Groups of diseases (average of 30 years). The upper thin line repre- 

 sents weekly averages from all causes of death whatever ; and the thick black 

 line, from all causes minus violent deaths. The red space embraces deaths 

 from all bowel complaints ; and it will be observed that the subtraction of 

 these diseases takes away the summer maximum from the general curve. 

 The blue space embraces all diseases of the respiratory organs ; and the dark 

 space, diseases of the brain and consumption. 



The mean weekly temperature is represented by the red line. 



Prepared by Alexander Buchan, Secretary, and Dr. Arthur Mitchell, 

 Chairman of the Medico-climatological Committee, and published in the 

 Society's Journal, vol. iv., p. 187. 



2920. Diagrams, showing the influence of weather on mortality 

 from different diseases and at different ages. Nos. II. and III.

D. Showing mortality curves from special diseases, viz., small-pox, measles, 

 whooping-cough, scarlet fever, typhus and typhoid fevers, erysipelas, metria, 

 rheumatism, pleurisy, and pericarditis.
