1874, and finds that the average date corresponding to the 

 whole twenty-five phenomena is, for the eighteenth century, 

 April 7, and for the nineteenth century March 28, showing 

 that the springs are now nine days earlier than they were 

 one hundred years ago. These dates are based respectively 

 upon 196 and 181 observations; and it is not probable that 

 the difference is owing to any fault of observing, but it is 

 possibly due to drainage or cultivation. The extreme vari- 

 ability even of the English climate is illustrated by the range 

 in the dates of certain phenomena. Thus, turnips are report- 

 ed in flower December 25, 1846, and May 14, 1784. The 

 wood -anemone was observed in flower March 9, 1775, and 

 April 30, 1837. The average range of phenomena noted by 

 Mr. Marsham is about seventy days. Transactions of the

METEOROLOGY IX NEW SOUTH WALES. 



The private observatory of Mr. John Tebbutt, of Windsor, 

 New South Wales, contributes to the meteorology of that 

 part of the world a volume of observations made from 1867 

 to 1870, which observations have been recorded regularly at 

 9 A.M., and are supplemented by the records of self-register- 

 ing maximum and minimum thermometers. The geograph- 

 ical position of the observatory has been determined by an 

 extended series of observations of moon -culminating stars 

 for longitude, and by observations in the prime vertical for 

 latitude. The observatory is also connected by telegraph 

 with the Sydney Observatory, which has, until recently, been 

 under the directorship of Rev. W. Scott. The observatory 

 of Mr. Tebbutt is situated on a hill near the centre of the pen- 

 insula at the eastern extremity of the town of Windsor. It 

 is about 28 miles from the sea-coast on the east, and about 8 

 miles from the Blue Mountains on the west, and is surround- 

 ed by the forest except in its immediate neighborhood, where 

 the soil has been cleared and cultivated for more than fifty 

 years. Many of the meteorological instruments used in 

 these observations were made in Sydney; others were 

 brought from England, where they had been carefully com- 

 pared with accepted standards. From the tables given in 

 this volume of observations, it appears that the total amount 

 of rain, as measured at Windsor, has been, in 1867, 44 inches;
