ABSTRACT OP PROCEEDINGS. XI. 



liquor was heated in a digester at 6 atmos. pressure for one 

 hour. It became turbid and dark brown in colour. The 

 precipitate which was not bulky, was removed by filtration 

 and the liquid was heated in a steam sterilizer on three 

 successive days. The brown solution of peptone contained 

 0*48% nitrogen corresponding to 3% peptone. The alka- 

 linity to phenol-phthalein was such that 100 c.cm. solution 

 required 4*0 c.cm. N/10 acid to abolish the pink colour of 

 the indicator. The solution had been used to make the 

 media. 



2. Mr. R. T. Baker exhibited a section of the North 

 American Redwood (Sequoia sempervirens) taken from a 

 tree grown at Reefton, New Zealand. It illustrates a 

 rapidity of growth of secondary wood that is perhaps a 

 world's record, the diameter of the tree measuring 2 feet 

 10J inches, at the age of 27 years; the width of each annual 

 ring is about one inch. 



3. Dr. J. B. Olbland exhibited some beautiful coloured 

 drawings, remarkable for their almost microscopic exacti- 

 tude, of two Australian polyporoid fungi, kindly drawn by 

 Mr. H. Butler of Derby, England, from specimens sent to 

 him; also a series of watercolours of some of our larger 

 soft fungi prepared by Miss Phyllis Clarke.
