Mr. White said it was impossible to treat the tides dynamically. 

 The best mathematicians had tackled the subject, but it was still 

 said that the dynamical theory was a disgrace to science. The 

 tides at the Port Phillip Heads difiered from the Admiralty tables 

 by four hours. 



Mr. Ellery said that Mr. Wakelin in all his papers started a 

 speculation, but went no further. 



Dr. Wild noticed that Mr. Wakelin stated that he had a 

 difficulty in obtaining books to consult. That partly accounted 

 for his inability to conceive how the small moon could raise the 

 waters of the ocean against the attraction of the earth. 



After a few more remarks the discussion terminated.

 fauna and flora of Port Phillip be compiled, and that annual 

 additions should be made of such similar publications as shall 

 appear in each succeeding year. It was decided that by Port 

 Phillip should be indicated the salt waters inside of a straight 

 line joining Point Lonsdale to Point Nepean. That the
