which he had secured during a recent dredging excursion at 

 Flinders, Western Port Bay, dealing with them according to their 

 places in systematic zoology, and illustrating his remarks with 

 specimens and blackboard drawings. 



The paper created considerable interest, and gave rise to some 

 discussion.

EXCURSION TO BLACKROCK. 



Blackrock, on the shores of Port Phillip Bay, between 

 Sandringham and Beaumaris, was visited by a fair party of 

 members on Saturday, 24th February, who devoted the afternoon 

 to studying the marine zoology and botany of the locality. 



Mr. O. A. Sayce, who acted as leader of the zoological 

 section, reports that for best results in collecting shore fauna 

 it is important to have low tide, and in this respect the party on 

 Saturday, 24th February, was somewhat unfortunate, as very few 

 rock-pools, which are always abundant of life, were isolated from 

 the sea. However, by wading and turning over stones and 

 searching amongst floating weed, some interesting forms were 

 found. Of Porifera, or Sponges, a few young living forms 

 attached to weed, suitable for microscopical examination without 

 any preparation ; also from the same source one or two 

 Hydrozoa, and a living Polyzoa, which proved of interest and 

 profit when examined by the microscope during the evening and 

 seen with each polyp extended from its cell or zooecium. It is 

 when seeing objects such as this in a living condition that the 

 truth comes home that zoology is comparatively a barren study 

 if the objects are only seen when dead, and the need of "field " 

 observation is realized as it should be.
