In t 28th of February in tbe year 1825, the Garden Committee of he lyal Horticultural Society resolved that it was expedient that a fete ological Journal should be kept at Chiswick in the gardens of ae biety ; and observations were commenced on the 1st of May, but ’om he difficulties experienced in obtaining efficient instruments and thei Circumstances the observations to the end of the year were not ansi red to be sufficiently perfect for publication. Fn the 1st day of January 1826 to the 31st day of December 1869, owesr, the observations were made upon one uniform plan through- atjjll June 1830 by Mr. William Beattie Booth, A.L.S., and from fiat ite, with but few exceptions which are not specified, by Mr. lobe Thompson, under-gardener in the fruit department. Th observations during the whole of this period of 44 years have een ade at three different times in the day, designated in the journals s m( ling, noon, and night ; and included the readings of the barometer, empjature of the air and either a Daniell’s hygrometer or a wettened- ulb lermometer as well as maximum and minimum temperatures bth ilar and terrestrial readings, fall of rain, direction and strength ftb vind hy estimation, and brief notes. Tt morning observations are stated to have been made at 6 o’clock a tb summer months, and at daybreak in the winter months ; the Mm bservation was made between noon and 1 p.m., and the night bse:ffion between the hours of 9 p.m. and 10 p.m. hi'ie reduction of the observations I have considered the morning bseution to have been made at 6 o’clock a.m. in the months of April o ^gust; at 6.30 a.m. in the months of March, September and )cto r ; at 7 a.m. in the months of February and November ; and at AMjin the months of January and December ; that the noon observa- lonsjave been made midway between noon and 1 p.m., and the night delations at 9.30 p.m. throughout the year. Cc iidering that temperature is the most important meteorological hm t bearing upon all animal and vegetable life, and also considering 'hat jie science of open-air horticulture needs a full knowledge of the b 2 4 extremes and means of climatic temperature ; the horticultuit ha to contend with so great a difference in the distribution of taper! at the same season in different years, that it is of the first iiporf to determine accurately the average of temperature of every ay h year, with the extremes to which it is liable. It is known th the disturbance of the animal econcfrny takes place when the rmn te rature of the air is that of the average of the season, and tlj gre ' disturbances take place whenever the temperature of the ir de] the greatest, either above or below that average ; and there iiuo d that the same general law affects all vegetation in a simila! mai and that the effect follows the cause after an interval of tinn It these considerations which induced me to confine my first renctic this long series of observations to temperature alone. The instruments used were A Daniell’s hygrometer, and maximum and minimum thenom of Rutherford’s construction made by Newman. (These thenom were placed in an open spot in the Arboretum, screened frorthe of the sun and sheltered from radiation by a kind of umbrell of ■ cloth ; they were attached to the northern side of the post viicli ported the umbrella, and are four feet above the ground. — See-age Yol. vii. Trans. Sort. Soc .) There is no record of change of instruments. The scale sed that of Fahrenheit, except in the years 1885, 1886, and 1837, her centigrade scale was used. Till the year 1844 there are no MSS. observations, but thefbse tions are published in extenso in the Transactions of t. It Sorticultural Society. From the year 1845 the observatior an MSS. The first process in the reduction of the observations wa da^ day, to see that the several thermometrical observations in he were less than the maximum and greater than the minimal am note all discordant readings. The second step was to examine these discordant readings for purpose all the observations made at the Royal Observatory, Ghfenw on that day were consulted, for readings taken at about the sai.3 tii and to determine the general course of increasing and dereas readings, and amount of change. A great many errors we t found, principally in the readings of the minimum fhermomeh The third process was to take the daily sums and means of lie tl observations of morning, noon, and night temperatures, fora i approximation of mean daily temperature. The fourth was to take the daily sums and means of the irjxim and minimum temperatures, for a second approximation t d* ‘ daily temperature. The h was to take the daily differences between the maximum and lain!! temperatures, for daily range. Next to deduce from each of ege jroximate true mean daily values, by the application of rrecti is as calculated from my Tables of Diurnal Range. The 1 erections to be applied to the mean of the three daily observa- ,ns v e as follows (dependent on the time of the year, the times of serv; m, and the daily range of temperature) : — o O [n h try when the daily range was 7 the correction was 0*1 subtracts it 30 a 0-7 ,, „ F( lary a „ 7 a 0-1 additive 1 1 it 36 a 0-4 I M h 1 1 1 ,, o-i J) a it 10 0-7 1 1 1 20 )9 1-4 if a 30 a 2-0 ,, „ A . 1 ,, o-i a 10 1 1 0-7 ,, ! y j >9 20 ) t 1-3 j J9 30 1 1 1-9 ,, 40 2-5 Tm a a 2 0-1 H 1 - y it 20 ,, 0-6 1 30 » ) 0-8 , J; if a 10 y > 01 ,, „ i i a 40 0-4 „ J, 1 1 a 6 • ,, o-i » | a a 40 06 ,, „ A ast a 1 , , o-i „ 1 a 10 0-4 ” 1 a 20 a 0-7 ,, y9 1 1 30 it 11 ,, a a 40 a 1-5 i. {jhember a 2 99 01 ,, » it tr 10 0-5 M } ft a a 20 1-1 ,, „ 1 „ a a 30 1-7 „ i, 1 „ a t i 40 2-2 ,, i> ^ber j j a 1 a 0-1 ,, , a a 40 t i 0-6 'it lr. and Dec. „ 1 1 1 i t 0-1 subtractiv* ” 1 . a 30 » 0-4 a lies< iser le? 'as r lade feqtij corrections were applied daily to the mean of the three daily tions to determine the true mean daily temperature throughout )le times, excepting the three years when the centigrade scale nrtunately used. I say unfortunately, for the observations were o the whole degree only, and thus the error of reading was % as large as 1° Fah. A mean correction belonging to each 6 month was thought sufficient during these three years. he d process was to apply a correction daily to the mean of the nxim theca and minimum temperatures, dependent upon the time of rear. deduce from these a second approximation to the true men temperature, and which corrections are as follows : — January 1 to January 7 99 8 „ 22 ,, 23 „ February 5 February 6 „ 18 ,, 19 „ 25 ,, 26 „ March 1 March 2 „ 4 5 „ 8 ,, 9 „ 13 ,, 14 „ 16 ,, 17 „ 22 ,, \ 23 „ 29 „ 30 „ April 5 April 6 „ „ 12 ,, 13 „ „ 19 ,, 20 „ May 1 May 2 „ „ 30 „ 31 ,, June 30 July 1 », July 25 „ 26 ,, August 8 August 9 „ „ 21 „ 22 „ 29 „ 30 ,, September 5 September 6 >, ' » 11 ,, 12 „ „ 19 39 20 „ ' „ 28 99 29 „ October 10 October 11 „ „ 20 „ 21 „ „ 26 „ 27 „ „ 31 November 1 ,, November 3 >> 4 >> M 8 „ 9 „ 13 14 „ 17 „ 18 „ ,, 23 „ 24 „ December 1 December 2 „ „ 11 99 12 „ 24 99 25 „ 31 the correction was 0-1 subtrdive 0*2 leqt land 1 By the application of these numbers a second mean daily tempratn was formed. The next process was to compare the daily results deduced Dm t] three observations with that found from the maximum and niimu 7 J ieratures — tlie two results should be alike, or nearly so ; and when tbj was not the case, to note all instances of discordance. len to examine a second time all Greenwich records on those days, to! .’ace the source of discordance ; the errors thus found were mostly b< aging to the morning or noon observations. be last step was to combine the results found by the two methods tc ther, for the determination of the most probable mean temperature oii rer y day, as found from all the observations taken that day, and in t] way Tables I. to XII. were formed. he numbers in the first column are the days of the month, those in t] following forty- four are the mean temperatures of the same day of t] month in the successive years ; the forty-sixth column contains the n n temperature of every day, as deduced from the forty-four years o ovations, and each value, therefore, is based upon about 220 obser- v ons, spread equally over the period. The remaining columns contain t highest and lowest mean daily temperatures within the periods, a the last column the difference between them. , he numbers in the bottom line are the means of all the numbers in tj columns above them, and therefore are the mean temperatures of e i month ; each result is based upon 150 observations nearly ; the v )le number of observations treated of in this paper exceed 80,000.

December 8 times, in March once, and in November once. These un- usual circumstances took place in the years 1837 and 1851 respectively. | The hottest month has occurred twice in June, 27 times in July, and 15 times in August. The month of lowest temperature was January 1838 ; and of highest was July 1852. By taking the mean of all the values for each month, we find : — The mean temperature of January was 37 A „ „ February „ 39A ,, ,, March „ 42-4 „ „ April „ 48-2 ' May „ 54-4 „ „ June „ 60-5 July „ 63-1 ,, „ August „ 622 ,, ,, September „ 57-6 „ „ October „ 50-4 „ r „ November 42-7 ,, December „ 40-0 And the mean of these gives 49°‘9 as the mean yearly temperature. By taking the means of the numbers in each horizontal line, the mean temperature for each year is determined as follows : — TABLE. XV. — Mean Temperature of every Year , 1826-1869.

The year of highest temperature was 1868, and v | value was 52°*3. jjThe mean temperatures of the years 1829, 1838, 1855, and 1860, est|re all below 48°. The year of lowest temperature was 1860, and its line was 47°'l. Thus 44 years, from 1826 to 1869 inclusive, give a mean tempera- ire of 49°‘9, with a variation, between one year and another, from |°*1 in 1860 to 52°-3 in 1868. The difference is 50,2.

HXXVII. were formed, those days of excess of temperature being Kpguished by the sign phis ( + ), and those of defect of temperature being denoted by the sign minus (— ). ■.glance at these Tables shows that the differences from day to day are [very great, and that the temperature of the same day is very different in different years. At times it will be seen there have been long periods together with one or other sign prevailing, but that there have been but few months in wliich on every day of the month it has been either always above or below the average ; the only instances are [February 1853, July 1857, and August 1860, during which months [every day was cold and of lower temperature than the average ; and October 1831, in which every day was warm and of higher temperature than the average. There are, however, a few having but one with gjjher a + or — sign and all the remainder affected with the opposite sign ; they are : — January, 1830 and 1834 February, 1855 April, 1844 June, 1860 November, 1851 December, 1852 ■very other month there have been two or more days with different *>gns. It will thus be seen how very rarely every day of a month has heeii wholly of high or wholly of low temperature.

There are in the Table, viz., February 1853, July and August 1860, and Octob< 1831, showing, as before, that these are the only four months of oi temperature throughout, three being cold and one warm. By picking out under each month the largest number with a + sig and the largest number with a — sign, the extreme departures in eac month in 44 years will be shown, and are as follows : o In January the greatest excess on any one day was 16-0 in the year 1828 „ February „ „ 16-9 1831 ,, March „ „ 14-7 1826 ,, April ,, „ 161 1828 „ May 17-6 1847 „ June „ ,, 167 1858 » July 15-4 1868 ,, August }> ,, 14-5 1842 „ September ,, 12-1 1865 „ October ,, 11-9 1831 ,, November ,, „ 159 1852 ,, December ,, 13-9 1856 And In January the greatest deficiency on any O one day was 29'6 in the year 1838 „ February ,, ,, 22-4 1855 March „ 22-3 >> 1845 „ April ,, „ 16-8 ?? 1861 „ May „ 16-5 M 1867 ,, June „ 27*2 n 1869 >> July 16-2 » 1856 ,, August 12*1 > > 1867 ,, September ,, ,, 12-1 yy 1860 „ October „ ,, 18-6 ; J 1859 ,, November ,, „ 21*5 5J 1858 „ December „ 20-5 M 1844 In every month, with the exception of May and August, the extreib deficiency of temperature is larger than the extreme excess, and ver largely so in many months. The greatest excess of temperature during the 44 years was 17°'; this took place on May 28, 1847 ; and the greatest deficiency was 29° , on January 20, 1838. These extremes of temperature affect vegetation greatly, but tlr seldom occur alone ; it is very necessary for the operations of open-; ’ horticulturists to know for what lengthened periods these departure from averages may extend. By looking over Tables XVI. to XXVII.,- 23 will be seen that very often there are long groups of •+■ or — quan- 1 tities, and that frequently several of the numbers are very large to which these signs are attached ; and it is the accumulation of these | departures, more than in isolated cases, which requires the attention of the horticulturist. These periods are variable in length, frequently of a week’s duration, and less frequently of a fortnight ; taking the ! latter as a limit, the following numbers show all the periods of excess of 14 days’ or more than 14 days’ continuance. By taking the periods of excess above the average in each month, in which the number of days extend to 14 or more, and entering 1 them opposite the month in which the period commences, we have the following : — 1828 January 17 to February 8. equal 23 days 1835 n 23 11 11 8 17 * 1840 n 14 11 January 29 11 16 11 1846 >} 13 11 February 7 11 26 tl 1849 9) 13 11 January 28 11 16 11 1863 11 18 11 February 8 1) 22 11 1866 If 26 11 11 12 11 18 11 1869 1} 28 11 21 » 25 11 1828 February 19 11 March 4 11 15 91 1831 11 24 11 11 13 11 18 11 1834 11 18 11 11 12 23 11 1835 11 11 11 February 27 11 17 11 1837 11 8 11 „ 23 11 16 11 1846 11 16 11 March 11 11 24 1 1 1848 11 3 11 February 16 11 14 11 1859 M 9 11 11 22 14 91 1863 11 19 11 March 8 11 18 11 1867 11 1 11 February 26 11 26 11 1868 17 » March 7 11 19 11 1828 March 8 11 21 91 14 11 1830 i) 8 11 11 31 11 24 11 1841 „ 5 „ April 1 11 28 11 1842 „ 7 11 March 20 14 11 1843 11 11 26 11 16 n 1-848 „ 22 „ April 5 15 1850 ,, 30 11 „ 19 11 22 11 1857 26 „ 11 10 11 16 11 1862 » 24 11 » 7 11 15 11 1826 April 2 11 11 23 11 22 If' 1827 ,, 2 11 17 11 16 11 1830 20 May 8 11 19 11 1831 11 19 4 11 16 11 1834 27 1 5 ,, 16 11 20 11 1840 20 » »» 16 27 11 1844 1863 1867 1868 1828 1833 1841 1846 1848 1858 1859 1868 1826 1826 1828 1831 1836 1837 1842 1859 1827 1831 1834 1835 1852 1856 1868 1826 1837 1842 1831 1843 1846 1859 1861 1865 1868 1826 1849 1852 1853 1856 1863 1827 1828 24 April 8 to May 14 equal 37 days ,, 8 „ April 28 21 „ 1 „ ,, 20 20 „ ” 15 „ May 4 20 „ May 6 „ 99 19 14 „ 1 » ,, 25 25 „ 21 „ June 5 16 „ 29 „ 5) 22 25 ,, 3 „ May 18 16 „ 29 „ June 17 20 „ >> 24 „ 13 21 „ » 8 „ May 22 15 „ June 6 „ June 20 15 „ 23 „ July 15 „ 23 „ 22 „ 11 20 „ 9 >> June 23 15 „ 26 „ July 13 18 „ 12 „ June 25 14 „ 3 „ 17 15 „ » 30 „ July 23 24 „ July 6 „ >9 20 15 „ „ 26 „ August 17 23 „ ,, 28 „ ,, 21 25 j;

By taking the algebraical means of the values in each column of ! tbles XVI. to XXVII., the following Table was formed. I By looking over this Table at the general distribution of the -f- and signs, the most remarkable fact is the preponderance of + signs in 3 month of January, towards the end of the series, over those at the 28 o rO e On d July X <^5 e s* X H £ W l-si "+* PQ 3 <1 Jl >1 r ) L ' 05 rO § GOt'^CO'^'T-'^OOt^ M « ffl Til N H >b + + + I I + + + 50 i-H CO CO O O^hAcOJ'- + + I + I N N H N N r^-l CO CO CO C + + I + + 7 CO o (fa • - M CCt^ - z CO '-I + + co + I I fs co 7 at- _- T T i 71' . — i © co co + + I + co o I I CO to 7 © 00 b-( + I + 'c - 05 7 © O fl H I i I co »o 00 © + + CO o 1>- -b ©COWOO0 0 « * w-) vo 00 00 CO CO CO CO CO CO CO cooooooocooooooooooooo « CO t So , ■cj- ^ f 10 1 oo 00 Note.— The sign plus ( + ) signifies above the average, and the sign minus ( — ) below the average. 30 beginning of tlie series ; it is a fact well worthy the thouglitfi attention of all horticulturists ; the same thing is also shown i February, but to a less degree. Then, on the contrary, in the montl of May, June, and July, the + signs seem to be more frequent at tl beginning of the series than towards the end ; particularly this i shown in the month of July, implying that our winter months ai somewhat warmer, and our summer months somewhat colder, tha . formerly. It will be seen that the same months have frequently been eithc above or below the average for three or four years in succession. By selecting under each month the largest number with the + sig and the largest number with the — sign, the warmest and coldest J fij the several months are shown, and are as follows : — o o ll'fl In January the greatest excess was S’2 in 1834, and greatest deficiency was 8‘6 in 181 „ ,, February „ March „ April „ May „ June „ July ,, August „ September ,, October ,, November „ December Therefore the largest monthly excess of temperature was 8°“2 ii January 1834, and the largest deficiency was 10o,6 in February 1855 By taking the means of the numbers in each horizontal line i Table XXIX., the departure from the average of each year’s ten perature will be shown, divided into two groups of warm and col and are as follows : — Warm Years O Cold Years o In 1826 too high by 1*5 In 1829 too low by 2‘0 „ 1827 11 „ 1836 „ 0*5 „ 1828 2-3 „ 1837 1-1 „ 1830 o-i 1838 ,. 2-1 00 oo 2-2 „ 1840 1*0 „ 1832 0-2 „ 1841 o-l 1833 0'5 „ 1844 04 „ 1834 2-3 lO OO 1-8 „ 1835 0-7 „ 1847 0-2 „ 1842 0-7 „ 1850 0-9 „ 1843 0-4 „ 1851 0-2 „ 1846 1-8 , 1853 1*8 „ 1848 0-2 1854 0-6 5-8 , , 1869 „ 10-6 . . 18- 6-1 , , 1830 „ 5-6 , , 18i 4-6 , , 1865 ,. 6-1 . . 18; 6*6 , , 1833 n 4-9 , , 18; '• 6-3 , , 1846 „ 52 , . 18i. 5-6 , , 1868 „ 4*5 , , 18< 5-0 , , 1842 „ 4-0 , , 18(j » 5-1 , , 1865 „ 4;3 , , 18* ,18. 6-5 , , 1831 „ 5-0 , ' -1 5-8 , , 1852 5-6 , . 18. 7-2 „ , 1852 „ 7'6 , . 18 31 Warm Years o Cold Years O In 1849 too high by 0-2 In 1855 too low by 2-7 „ 1852 1*0 „ 1856 0-7 t'- iO 00 1-1 00 kC 00 0-5 „ 1859 0-7 „ 1860 2-8 „ 1862 0-1 „ 1861 0-6 1863 1-0 „ 1864 1-2 „ 1865 0-4 „ 1867 0-7 „ 1866 0-5 „ 1868 2-4 „ 1869 0*1 The year 1839 was of the average temperature. The warm years 1828, 1831, 1834, and 1868 were all 2°£ above the average : the year of greatest excess was 1868. The cold years 1829, 1838, 1855, and 1860 were from 2o,0 to 2°-8 below the "average : the year of greatest deficiency was 1860. Thus in 44 years, the temperature of 23 have been above ; 20 below, and one of the average value. It is remarkable that from 1826 to 1835, with the single exception of 1829, every year was above the average ; and those from 1836 to 1841, with the exception of 1839, which was just the average, all were below ; and since then the only group of four or five years together of the same character in this respect were those from 1850 to 1856 (with the exception of 1852), which were below their averages. 'Since the year 1856, warm and cold years have been almost alternate. ON THE DAILY RANGES OF TEMPERATURE ON EVERY DAY OE THE YEAR FROM ALL THE MAXIMUM AND MINIMUM HEADINGS OF THERMOMETERS TAKEN AT THE HORTICULTURAL GARDENS AT CHISWICK FROM THE YEAR 1826 TO THE END OF 1869 D DAILY RANGES OF TEMPERATURE. r is found that animal life is best preserved wben the temperature f each season is that of its average, and when the range of tempe- iture is also that of the average, and that sickness and death follow jay great departure from these averages. The occasional destruction of shrubs and fruit-trees by the cold of S inter is very distressing and very annoying;, and this sometimes takes lace when the mean temperature of the aiP is the same as the plant is previously endured without injury ; but the mean temperature of a i ariod does not represent the actual temperature to which the plant Us been subjected. The mean temperature may be based upon a | mge of temperature corresponding to the average, or it may be from jie much smaller or much larger than the average ; and in the latter ; ise the plant is subjected to the injurious effect of alternate very high Ud very low temperatures, and in winter time this would imply a ] iriod, and perhaps a long one, in which the temperature was below h° Fahr, i It is very important that the agriculturist and out- door horticulturist l .ould know the ranges of temperature to which plants are exposed in j e open air. This variation of temperature differs day by day and I onth by month ; and it is only after a long series of observations II at we are able to determine the average daily range in every season, le readings of the maximum and minimum thermometers have been ’ ken continuously at Chiswick since 1826, and the difference between 1 ese values gives the range of temperature on each day throughout He period comprised between the years 1826— 1869. Collecting these mth by month and arranging them in parallel columns for different i ars, we have at one opening the ranges of temperature on every day | roughout that month for the whole forty-four years, and thus Tables NX. to XLI. were formed. 36 Looking over the numbers in these Tables we see that in any monti 1 the range may be as small as 1° to 5°, and as large as from 30° to 4C;| in the winter months, and exceeding 40° by several degrees in tb t summer months. That frequently several days of small range corr:l together, indicative of so many days of cloudy skies ; and several daj j of larger range come together, indicating periods of clear skies. By looking at the numbers on the same horizontal line, or the daill ranges of temperature on the same day of the month in different yearl similar large differences appear ; for instance on January 1 in the yeJ 1837 the range was 23°, whilst in 1851 and 1859 on the same day 1 the year it was 3° only. Great varieties are thus shown on every day t| comparing the results of different years together, or the numbers cl the same horizontal line in the several Tables. These results, being dependent on the different directions of the win- the more or less cloudy state of the sky, and the different conditions i the weather generally, are as variable as the weather itself. The maximum and minimum temperatures from which these resul have been obtained are not given in these series of Tables, but tlnj may be found approximately on any day by adding one-half of tl range to the mean temperature of the same day, Table I. to XII., f< the maximum, and by subtracting one-half of the range from til mean temperature for the day for the minimum. By selecting the smallest and largest range in each month in all tl years Table XLII. has been formed. This Table shows very clearly how variable the range of temperatui may be in twenty- four hours, and how very different in different yeail For instance, in the month of January under 1 greatest ’ in the ye I 1833, the largest range inany one day was 15°, whilstin general it exceei 20°, and in some years it has been as large as 30°. On the contra J under ‘ least ’ in the years 1828 and 1854 the range has been as sm;l as 1°, and by looking down the column it will be seen that ranges I small as 2° or 3° are common, whilst in other years there has been p range less than 8° or 9°. As small daily ranges have taken place i January and December, as 1° ; in February and November as 2° ; i March, April, and October as 3°, in June and September as 4° ; al in July and August as 5°. As large daily ranges as 32° have taka place in the months of January and December ; of 34° in November of 38° in February ; of 39° in March ; of 42° in June and October ; 1 44° in May ; of 45° in July ; of 48° in April, and one of 49° in Augit 1861, which is the largest in the Table. By taking the mean of all the daily ranges in each year, or the me a of the numbers in every vertical column in Tables XXX. to XI., Table XLIII. is formed. From these numbers we see that the mean monthly daily range If temperature has varied TABLE XXX.

Mean daily ranges, differing so greatly in eacli month, may well be attended with different agricultural and horticultur al results. The numbers in the bottom line show the average daily range in each month ; and by taking the difference between these numbers and those in each year, the departure from the average will be found. The gradual increasing numbers, from January 12°*2 to July 28°-5, and the gradual decrease month by month to December 120,2, the same as January, indicates the annual law of daily range of tempera¬ ture. By taking the mean of all the daily ranges on the same day of the year from a'll the years, or the means of the numbers in every horizontal line in Tables XXX. to XLI. Table XLIY. was formed. By selecting the least and greatest of these mean values in each month we find that the mean daily range of temperature has varied In January, from 97 on the 11th day to 15‘0 on the 29th „ February, „ 12-4 „ 2nd „ 16*4 „ 17th ,, March, „ 13-6 „ 2nd 20-4 „ 31st „ April, „ 18*4 ( 9th and > ” } 12th J ” 235 „ 20th „ May, „ 20-9 „ 1st 24-6 „ 17th ,, June, „ 21-2 ,, 7th ,, 25-3 „ 23rd » July, 20'9 „ 24th 26-8 „ 5th „ August, „ 20-9 „ 6 th 247 „ 4th „ September, „ 197 ( 1 6th and ) ” l 28th \ ” 247 „ 12th „ October, ,, 15-5 „ 31st 21-1 1 5 th and ” l 6th „ November, „ 13-0 „ 23rd 16-9 „ 3rd „ December, „ 10-8 „ 21st „ 14-1 ,, 25th. The smallest range in the year is therefore on January 15, and the largest is on July 5. By taking the mean of all the numbers in each column the mean monthly daily range is shown ; these are the same as in the bottom line of Table XLIII., and these agreements are a proof of the general accuracy of the work.

The rain-gauge with which the observations were at first made, is stated to have been constructed according to Mr. Howard’s directions in his work upon the Climate of London (see vol. vii. of the 1 Transactions of the Society, page 100), and the following description is extracted from that work : — ~ 1 The rain-gauge consists of three pieces, a funnel, a bottle, and the measure. The funnel is most conveniently made of five inches opening, and of the form represented in the figure : the mouth-piece of brass’ turned in a lathe, the remainder of tinned copper. It has two necks : the inner and longer one, widening a little downwards, enters deep into the bottle, and conveys the rain : the outer neck is soldered on the cone of 48 the funnel, having no opening into the latter : it serves the necessary purpose of preventing the entrance of water from the outside ; and by resting on the shoulder of the bottle, it gives steadiness to the funnel. 4 As to the bottle, a common wine-quart will contain from two to two and a half inches of rain on this funnel : but it is better to use a three- pint bottle (technically termed a Winchester- quart), which has the proportions given in the figure. For an unusual fall of rain may happen, when a previous quantity has not been measured out ; and it is on such occasions that we would wish, more especially, to be certain of the amount. 1 A cylindrical glass of the depth of eight inches, exclusive of its foot, and lJj- inch in diameter, serves to make the measure. It is graduated into parts, each of which is equal in capacity to the depth of ^ of an inch on the area of the mouth of the fonnel. A glass of the above size will measure out fifty such parts, or half an inch at once. The graduation is conducted on the principle (which is a medium between calculation and experiment) that a cylinder of water at a mean tem¬ perature, an inch deep5i and five inches in diameter, weighs 10 ounces troy. The hundredth part of this, or 48 grains, is accordingly taken for the graduating quantity, and the scale is formed by successive additions, at each of which the surface is marked. Considering the nature of this operation, which scarcely admits of our going to fractions of a grain, I suppose the above standard to be sufficiently correct. I have been accustomed to etch the scale on the glass with fluoric acid, but it is more conspicuous when engraved at the glass- cutter’s wheel. Previously to sending it for this purpose, the whole scale should be traced, either on a strip of paper pasted on before it, is divided, or in oil paint on the glass itself. A diamond, or steel point, may be used for engraving the scale, in default of other means.’ This gauge was not in use lately, but when changed I cannot find any record. The first step in this investigation was to form Tables precisely similar to those for the temperature of the air, showing at a glance the daily falls of rain on the same day of the year, throughout the series of forty-four years, and in this way Tables I. to XII. were formed.

The following are instances of very little or no rain for a fortnight together or more : — In January, „ February, „ March, „ April, ,, May, ,, June, „ July, ,, August, ,, September, ,, October, ,, November, ,, December, 1826, 1827, 1829, 1830, 1838, 1850, 1861. 1827, 1855, 1858, 1862. 1828, 1829, 1847, 1850, 1858. 1826, 1834, 1840, 1842, 1852, 1855, 1861, 1863, 1864. 1829, 1833, 1834, 1836, 1838, 1848, 1866. 1826, 1835, 1842, 1846, 1849, 1865, 1867, 1868. 1827, 1832, 1835, 1860, 1863, 1866, 1869. 1826, 1833, 1834, 1835, 1853, 1857, 1864, 1869. 1832, 1846, 1850, 1851, 1865, 1868. 1828, 1842, 1845, 1868. 1844, 1851, 1858, 1859, 1862, 1867. 1829, 1834, 1835, 1838, 1840, 1844, 1851, 1853, 1855, 1859, 1861, 1864, 1865.

December. The month in which long periods without rain have been most frequent is December, and those in which long periods have been least frequent are February and October. The longest intervals without rain in each month are as follows : — January, 1838 . ... 26 days.

The following are instances of long- continued rain, or rain falling every day for a fortnight together : — E 50 In January, 1834 and 1846. February, 1833. March, 1836. April, 1829 and 1867.

December, 1827, 1833. Thus, once only in the four months of February, March, May, and July has rain fallen consecutively for so long a period as 14 days. Of the remaining months there are five distinguished by two such cases in 44 years, viz., January, April, August, November, and December, and there are three such cases in June, five in September, and six in i October. Of other instances of 14 days or more of continuous rain running j from one month into the next, there are seven cases, viz., in 1836, , March 22 to April 9 ; 1843, May 14 to June 10 ; 1836, September 27 to j October 15 ; 1841, September 21 to October 18 ; 1855, September 28 : to October 1 7 ; 1840, October 26 to November 13 ; and 1841, November 26 to December 13. Of these the longest continuous rain was 28 days. , In looking over Tables I. to XII. it will be seen how, as a rule, the \ rain falls in gentle showers, and but seldom as very heavy rain. Falls ; of an inch in the day in the winter months are very unusual ; in the 44 j years there has been but one such fall in the months of January, | March, and December, and there has not been a single instance in the month of February. The greatest -fall in this month on one day was i on the 25th day in the year 1849, when the amount was 0’92 inch. All the instances of an inch of rain in the day in the 44 years are as i follows : — January 11, 1866 . . . In. . . l'OO July 15, 1841 . . . In. . . 1-46 March 20, 1862 . . . . . Ml ,, 24, 1849 . . .

The heaviest fall of all is T96 in. in October , 1857. By taking the sums of all the numbers in Tables I. to XII., month by mbnth, Table XIII. was formed, showing the monthly fall of rain for 44 years ; and by taking the sums of all the numbers, day by day, Table XIY. was formed, showing the sums of every fall of rain on every day of the year for 44 years : and by taking the sums of the numbers in Tables XIII. and XIY. the accuracy of all this work is proved. By looking over Table XIII. month by month we see that — In January, 1855, the fall of rain in the month was In. as small as 0‘10 99 „ 1866, 33 „ large as 3'72 February, 1832, 33 33 small as 0*23 „ „ 1833, „ 33 large as 3-98 March, 1850, 33 33 small as 0'13 „ „ 1862, „ 33 large as 3- 74 „ April, 1840, 33 33 small, as 0’06 ,, 1829, „ 33 large as 4-49 May 1844, 33 small as 0’25 5, „ 1843, 33 33 large as 5’26 June, 1849, ,, 33 small as 0*31 „ 1860, 33 33 large as 5‘15 ,, July, 1864, ,, 33 small as 0*50 3? „ 1834, 33 33 large as 6 "3 4 9 9 .

The following Table shows the yearly fall of rain in each year in the period 1826 — 1869 at Chiswick and at Greenwich for the same years Year. 1826 Chiswick. In. 21-8 Greenwich.

The least annnal rainfall at Chiswick was 15 ’8 inches, the year 1858. The greatest annnal rainfall at Chiswick was 32‘6 inches, the year 1852. By com¬ paring the falls of rain at Chiswick and Greenwich together, year by year, we see that generally the fall at Greenwich is the greater in amount, and this excess at times has continued for several years toge¬ ther. These instances are : — From 1826 to 1828, the excess in 3 years was 1837 to 1839, ,, 3 years was 1847 to 1853, ,, 7 years was 1857 to 1861, ,, 5 years was 1865 to 1869, ,, 5 years was In. 7-3 50 12-9 5-4 17-3 There is reason to fear that the rainfall at Chiswick in the last three or four years has been somewhat too small in amount. At times, however, it has been greater at Chiswick than at Green¬ wich. -These instances are : — The year 1829. ,, years 1832, 1833, and 1834. „ years 1836, 1840, 1843, 1845, 1846, 1854, 1855, 1856, 1863, and 1864. One year the amounts were the same, viz., in 1862. There are twenty- nine instances of Greenwich being in excess ; and fourteen of Chiswick being in excess. The mean at Chiswick is 23*5 inches, Greenwich is 24*5 inches, and 58 as the annual fall of rain, as found from the observations 1826 to 1869. By comparing the numbers in Table XIV. month by month we see that : — In January the sums vary from 0'86 on the 8th to 4*80 on the 12th „ February „ 55 0-88 „ 6th „ 4-18 „ 26th „ March h 55 0-84 „ 26th „ 3-89 „ 14th n April 55 1-08 » 19th „ 3-98 „ 25th „ May ,, 55 1-48 » 18th „ 4-36 „ 5th „ June ,, 55 1-20 „ 8th „ 4-83 „ 12th „ July i> 55 1-04 „ 2nd „ 4-81 „ 23rd „ August >> 55 1-58 28 th „ 6-05 ,, ,17th „ September > > 55 1-69 „ 5th „ 6-19 „ 28th ,, October >) 55 1-25 „ 13th „ 6*33 „ 22nd „ November n 55 1-60 „ 20th „ 5-17 „ 28th ,, December „ 55 0-91 „ 10th „ 3-42 „ 7th By taking the differences between these extremes in each month, we find that the smallest difference is in December, viz., 2'51 in., and the largest in October, viz., 5*08 in. By comparing the consecutive numbers in Table XIV. together very large differences are found, the largest of these in each month are as follows : — In. In January between the 10th and 11th days, the difference is 2-65 „ February 55 26th „ 27th 55 „ 2-28 ,, March 14th „ 15th 55 „ 2-17 „ April 25th „ 26th 55 „ 2-78 „ May 55 29th ,, 30th 55 „ 2-63 „ June 55 5 th „ 6th 5 5 3-20 „ July 55 1st „ 2nd 55 „ 3-05 „ August „ 12th ,, 13th 5 5 „ 3-91 ,, September 25th ,, 26 th 55 „ 4-22 ,, October 17th „ 18th 5 5 „ 3-80 ,, November „ 20th „ 21st 55 „ 2-83 „ December „ 23rd „ 24th „ „ 1-53 By comparing the amounts of the falls at different periods of the year, it is at once seen that the heaviest take place in the months of May to November, and the lightest, in the early months of the year. The day in the year distinguished by the smallest fall is March 26, with O' 84 in. for 44 years, the next in Order being January 8 and Fe¬ bruary 6. The day distinguished by the heaviest fall of the year is October 22, with 6’33 in. as the sum for 44 years ; the next in order are September 28 and September 26, with 6T9 in. and 6’09 in. respec¬ tively. By taking the sums of the numbers in Table XIV. in five-day periods 59 Table XV. was formed. On looking over tliis Table, we still find considerable differences in every month of the year, and that the sum lay periods vary In January from In. 9-67 6th to 10th, In. to 16-57 11th to 15th ,, February 8-68 15th „ 19th, „ 13-69 25th „ March 1st „ March 55 7-65 22nd „ 26th, „ 12-58 12th „ 16th „ April „ 9-46 16th „ 20th, „ 14-25 21st „ 25th „ May 55 11-40 16th „ 20th, „ 16-96 6th „ 10th „ June 55 13-61 20th „ 24th, „ 16-41 10th „ 14th „ July 13-09 June 30th „ 4th, „ 19-27 15th „ 19 th ,, August „ 12-21 24th „ 28th, „ 20-49 14th „ 18th ,, September 55 15-74 3rd „ 7th, „ 20-71 8th „ 12 th „ October 55 13-86 13 th „ 17th, „ 23-10 23rd „ 27th „ November 14-04 7th „ 11th, „ 18-53 27th „ Dec. 1st „ December 55 9-35 27 th „ 31st, „ 11-63 2nd ,, 6th Showing the Sum of Rainfall in Five-day Periods. 60 CO 05 05 <© o t;~ lO CC CO CO oo oo oo co o cb Ph , May 1st „ June 29th „ 170-45 ,, June 30th „ August 28th „ 201-53 „ August 29th „ October 27th „ 220-00 „ October 28th „ December 26th „ 165-80 The period of least fall of sixty days’ duration was from March 2 to April 30, and of the greatest from August 29 to October 27. Again, by taking periods of successive ninety days, we see that the sum — From January 1st to March 31st was 198-85 ,, April 1st ,, June 29th ,, 237"06 ,, June 30th „ September 27th ,, 308-01 ,, September 28th „ December 26th „ 279-32 But the sum of the falls in the ninety days from January 31 to April 30, was 192-5 in., being smaller than in the period from January 1 to March 31 ; and the sum of the falls in the ninety days September 8 to December 6, was 309 ’3 in., being larger than in the ninety days June 30 to September 27. Taking successive periods of 120 days, the sums of the falls are : — in. From January 1st to April 30th was 265‘46 „ May 1st „ August 28th ,, 371 "98 ,, August 29th „ December 26th ,, 385-80 64 But these sums do not represent the 120 days of greatest rain, the sum of the falls from July 30 to November 26 being 415‘0 in.; and that from June 30 to October 27 is 421'5 in., which represents the greatest in the year. Collecting together the several periods of least rain, we find that — The 5-day period of least rain was from March 22nd to March 26th „ 10 11 9 „ 22nd „ 31st „ 15 99 11 17th „ 31st „ 30 11 1} „ 2nd „ 31st „ 60 n 11 „ 2nd „ April 30th „ 90 11 „ January 31st „ „ 30th „ 120 99 „ 1st „ „ 30th Thus, all the periods of least falls of rain take place within the first 120 days of the year. In like manner, collecting the periods of heaviest falls, we find that: — The 5 -day period of heaviest rain was from October 23rd to October 27th „ 10 11 1 1 11 18th „ „ 27th „ 15 11 3 ,, Jy 13th „ „ 27th „ 30 11 1 , - September 28th „ „ 27th „ 60 91 1 , August 29th „ ,, 27th „ 90 11 1 , July 30th „ 27th „ 120 11 J , June 30th „ „ 27th Thus, all the periods of heaviest rains take place in the period from June 30 to -October 27.

F The minimum, as observed, appears between the 80th and 00th days of the year, and the maximum between the 290th and 300th days, and these are the same days as found at Greenwich. By drawing a line through the curve, giving equal weight to every point, the dotted curved line is drawn : if we consider this to represent the annual march of the fall of rain, it seems that the minimum is from the 80th to the 90th days ; that it increases gradually, but with checks, to a maximum about the 220th day, decreases a little after this, attains the maximum between the 290th and 300th days ; then rapidly decreases towards the end of the year, when a secondary minimum takes place, and increases to a winter maximum about the middle of January, agreeing in all its main characters with the results as found at Greenwich from fifty-five years’ observations.
