EXHIBITS. 



1. By the Rev. E. F. Pigot, s.j., Riverview College 

 Observatory. The exhibit shews the exact copy, to scale, 

 of a portion of the record of the recent Dardanelles earth- 

 quake on August 9th. The large waves seen are those of 

 the third phase, at the time of Sydney's maximum move- 

 ment. The largest wave here shewn had a complete period 

 of 18 seconds, and —ytnof the amplitude on the seismograph 

 record, viz. 0'162 of a millimetre, was the maximum dis- 

 placement from zero position of the earth-particles. This 

 wave reached Riverview at 12h. 52m. 55s. p.m., Sydney 

 standard time, about an hour and a quarter after the shock 

 itself. The earliest wave of the first phase of course 

 arrived much sooner, at llh. 50*0m. a.m., or 14 minutes 

 after the catastrophe. 



2. By Mr. J. H. Maiden. Volume I of two folio volumes 

 of original contemporary water colour drawings by John 

 William Lewin (1770-1819) of Sydney, of plants collected 

 by Allan Cunningham in various parts of New South 

 Wales, in 1817 and 1818. The writing in pencil is by Allan 

 Cunningham himself. 



The volumes, which are of considerable value, were pre- 

 sented to the Botanic Gardens by Lady W. Phipson Beale 

 of London, a native of Sydney, through the kind inter- 

 mediation of Professor Liversidge.
