average rate of miles per day on his assumption that the bottle 
travels continuously from time put over till when found. Of 
the above 492 bottles, 75 were thrown over by the author. As 
he has thrown over about 5000 bottles, it appears that about 
1} per cent. of them are afterwards found and reported. The 
probable courses followed by the 492 bottles above referred to 
are charted on maps accompanying the pajers, so that general 
results may be inferred. Seventy-two bottles are recorded as 
found on Victorian coasts west of Wilson’s Promontory, the 
general drift being easterly.” One travelled 10,000 miles, two 
8500, one 5700, and three over 4000 miles, the travel of the 
others, with two exceptions, is under 1000 miles. The rate of 
travel per day varies from 15 to 1-10th mile, the average being 
4 miles. It may be noted that the rates for the long-distance 
travels are generally high, being free from shore eddies, &c.

[ Abstract. | 
Tue author finds that the hypothesis of the permanency of 
oceanic areas and the stability of continents presents consider- 
able difficulty in connection with the geographical distribution 
of plants and animals, especially when viewed in the light of the 
evolution of organic forms. The identity of. generic forms, and 
even species from South Africa and the Australian Alps, is in- 
explicable under this hypothesis, and the author’s difficulties 
were increased when an attempt was made to co-relate the juras- 
sic floras of South Gippsland and India during his recent geo- 
logical surveys of the former area. The conclusion was 
forced upon him from the facts presented that large continental 
land surfaces must have existed during the ere eater part of the 
Mesozoic era, and have continued into the early Tertiary period 
over the greater part of the Indian, South Pacific, Southern, and 
Antarctic Oceans. The author proceeds to quote the opinions 
held by Sir Joseph Hooker, Huxley, Hutton, Wallace, and other 
Scientists in support of this opinion, and reserves for a further 
communication the observations he has been able to make on the 
orographic and botanic features of the higher regions of S.E. 
Australia and the Victorian coast line.
