    Unless tlie o])posite is expressly mentioned, all the mxmerical and other statements in the Tables must be understood to I’efer, not exclusively to the day indicated by the corresponding date, but to the interval between noon of that day and noon of the day indicated by the date immediately preceding. The amounts of the various substances estimated in 100 cubic feet of air are in all cases, except that of carbonic acid, exi)ressed in xmits of weight. The unit employed is the milligramme. In the case of carbonic acid the usual method of exjmessing the amount as so many volumes in 10,000 volumes of air has been followed. The “ dashes” in the Tables indicate experiments lost through known causes. The “ marks of interrogation,” on the other hand, indicate results departing so hir from the normal character as to be clearly erroneous, while it is impossible to state with certainty the cause of error. Uain-fall is expressed in inches, the velocity of the wind in miles per hour, and temperature in Fahrenheit degrees. The accompanying Map of Glasgow will, it is hoped, also contribute materially to the interpretation > of the results of analysis. In it the relative density of shading corresponds approximately with the density k of the population, and the black patches indicate the sites of manufactiu’ing establishments, from which 1 proceed large qxiantities of smoke or of noxious vapoims. The positions of the Stations referred to in the Tables are indicated upon the Map by special marks, and the localities in which these Stations are situated are named below. These names are employed in the Tables to designate the respective Stations. With respect to the Eaglesham Station, which will ai>pear in these Tables from August 1, it is to be explained that it is situated at a distance of about 3 miles to the south of the village of that name, and about 12 nriles in the same direction from Glasgow. It stands at an altitude of 997'5 feet above sea-level, upon the northern slope of the extended range of trap hills which forms to some extent a boundary to the counties of Ayr, Renfrew, and Lanark. The locality is so remote from manufacturing and even agricultural operations that the air and rain to be obtained there may be faiidy accepted as standards wherewith to compare the air and rain of Glasgow. It mil also be used for some special investigations regarding ozone and other constituents of the atmosphere.* Glasgow, ‘25(h Jiihj, 1877. I i * \4ih November, 1877.—Owing to the position necessarily chosen for this Station, which is with difficulty accessible j except in good weather, the arrangements were considerably delayed by the rains of the past summer and autumn, and ; though these are now complete, the season is too far advanced to permit of the apparatus being used before the end of next j spring, when the temperature at that altitude shall have risen so as to allow of the continuous use of the water, ou the flow \ of which the working of the apparatus depends.
