At the Macleay Museum, at the University of Sydney, Mr. 

 George Masters, the Curator, has cleaned and sorted a large 

 number of specimens of Australasian, <fec., insects in the tine 

 collection at the Museum, which is available for Members of the 

 Linnean Society and for all students of Natural History. 



At the Department of Mines the Curator of the Geological 

 Museum, Mr. G. W. Card, has been engaged of late principally 

 in the removal of the collections of rocks, minerals, and fossils 

 from the old Museum at the Department of Mines to the building 

 in the Domain formerly occupied by the Technological Museum 

 Collections. 



The following are a few notes relating to scientific work other 

 than that done at the Museums : — 



During the September Vacation a biological expedition was 

 organised by Professor Haswell to Jervis Bay, where a supply of 

 material was obtained for the investigation of the development 

 of the Port Jackson shark, Cestracion. The original work done 

 during last year at the Biological Laboratory at the University 

 related chiefly to the tape-worm larva (Polycercus) found in the 

 "squirting earthworm" of the scrubs of Illawarra and the Blue 

 Mountains. Dr. Martin's important researches at the Physio- 

 logical Laboratory at the University Medical School on the 

 eflfects of snake poison necessitated his further investigating the 

 phenomena of the clotting of the blood, and he has contributed 

 two valuable papers on this subject during the past year to the 

 Journal of Physiology.* f
