ANNIVERSARY ADDRESS OF THE PRESIDENT. 



caves, consisting of flint instruments of an entirely different character 

 from those of Amiens and Abbeville, of bones of Reindeer, Bos, and 

 other animals, would appear incredible to those who had not wit- 

 nessed the actual discovery and the immense stores collected on the 

 spot. They have been distributed, with the greatest liberality, by 

 Mr. Christy and M. Lartet to the various public museums and pri- 

 vate collections in Europe. 



In the spring of last year Mr. Christy proceeded, with other Mem- 

 bers of the Geological Society, to visit some interesting caves of the 

 same character as those in the Dordogne, which had been recently 

 discovered in Belgium, near Dinant on the Meuse; and it was 

 whilst proceeding thence to Switzerland, with M. and Madame 

 Lartet, that he was attacked by inflammation of the lungs, which 

 carried him off in a few days. He died on the 4th of May, at La Pa- 

 lisse, AUier, at the age of 54. He will be long regretted by ail who 

 knew him for his social qualities no less than for his scientific 

 attainments. 



Sir John William Lubbocz, the son of Sir John W. Lubbock, was 

 born on the 26th March, 1803. He was educated at Eton and at Tri- 

 nity College, Cambridge, where he took his degree in 1825. He was a 

 first-rate mathematician, and for many years was devoted to the pur- 

 suit of science, particularly that of astronomy, in connexion with 

 which he investigated many questions respecting the action of the 

 tides, the theory of the moon and the perturbation of the planets, and 

 the determination of the distance of a comet from the earth, and the 

 elements of its orbit. He was Treasurer to the Eoyal Society from 

 1830 to 1835, and again from 1838 to 1845, and was for many years 

 Vice- Chancellor of the University of London. In 1834 the Royal 

 Society awarded him one of their Royal Medals for his paper " On the 

 Tides," and in 1848 the Astronomical Society gave him a testimonial 

 for his " Researches on the Theory of Perturbation." In 1836 he de- 

 livered the Bakerian Lecture " On the Tides at the Port of London." 

 He was elected a Fellow of this Society in 1848. He contributed 

 many papers on scientific subjects to most of the learned Societies in 

 England, which were published in the Philosophical Transactions, 

 the Memoirs of the Royal Astronomical Society, the Philosophical 

 Magazine, the Transactions of -the Cambridge Philosophical Society, 

 and the Reports of the British Association. 



In addition to these communications he published several import- 

 ant works on astronomical and mathematical subjects between the 

 years 1830 and 1840, including ' A Treatise on Probability ' and an 

 ^Elementary Treatise on the computation of Eclipses and Occultations,' 

 in 1835 ; ' Remarks on the Classification of the different branches of 

 Human Knowledge,' in 1838 ; an * Elementary Treatise on the 

 Tides,' in 1839 ; and ' On the Heat of Yapour,' and on ' Astronomical 

 Refraction,' in 1840. In this year he succeeded to the Baronetcy 

 on the death of his father, and from this period appears to have 

 withdrawn himself somewhat from the active pursuit of scientific in- 

 vestigations. That they were not altogether given up is proved by
