418 MEETINGS. 



The second Lecture, by Mr. A. Colleiiette, F.C.S., 

 coiiL^isted mainly of experiments with solid carbonic acid. 

 To the audience this substance appeared like lumps of salt, 

 and Avater poured on a lump appeared to boil. The lecturer 

 explained how under great pressure the gas becomes solidified 

 without passing through an intermediate stage analogous to 

 water, and in this condition a very low temperature is 

 attained, so that a tube of mercury soon becomes solid. 

 It was possible that the polar snow caps of Mars consisted 

 of solid carbonic acid, and, if so, life as Ave know it could 

 not be sustained. 



The third Lecture by Mr. F. L. Tanner, L.D.S., was 

 entitled " Atlantis : a lost continent." In ancient times it 

 was believed that the great ocean separating Europe from 

 America had once been dry land, and modern research had 

 somewhat confirmed the idea, because it was now known 

 that seams of coal existed in the bed of the Atlantic. 

 This so-called continent was probably an island of vast 

 size. Slides were shown to illustrate the flora of the car- 

 boniferous period and the huge reptiles Avhich may have 

 had their home in this submerged area, gigantic animals 

 which were the ancestors of the present races of living 

 things. Among them were the remarkable Bird-reptiles from 

 which the birds trace their descent. 



The entertainment, besides giving pleasure to a large 

 number of people, proved very successful financially, and 

 after deducting all incident expenses the sum of £7 Is. 2d. 

 was added to the Society's funds. 



Monthly Meeting held on March 18th, 1908, Mi\ W. Sharp, 

 Vice-President, in the chair, 



Messrs. A. E. Jessup and A. C. Jessup were unanimously 

 elected members of the Society. 



The Hon. Secretary exhibited some strawberry leaves 

 bearing a parasitic fungus which had been identified at Kew 

 as Spmnaria alba, a species already recorded for this island. 



Mr. E. D. Marquand read some "Botanical Notes" 

 which are published in the present Transactions, and then 

 gave a brief description of the five classes of citizenship 

 into which all British plants are commonly divided, i.e., 

 natives, colonists, denizens, aliens and casuals. 



Mr. J. S. Hocart read a paper on the old Guernsey 

 Lamp or Crdsset, and exhibited a fine specimen of the lamp 

 itself and the stand on which it was usually hung ; also
