mens, he drove across to Coonabarabran and finished his field 

 work and collecting in the Warrumbungles, commenced in the 

 previous year. From the Warrumbungle Mountains he proceeded 

 to Dubbo to examine the alkaline rocks lately discovered there 

 by Mr. Myrton, Geological Surveyor of New South Wales. He 

 returned in the end of November after an absence of nearly three 

 months. Since his return Mr. Jensen has been occupied with 

 the petrological examination of the rocks collected, and is at 

 present making chemical analyses of some of the most interesting 

 types. Amongst the rocks collected were alkaline sj^enites, alka- 

 line (arfvedsonite) trachytes, tegirine-nepheline phonolites and 

 other alkaline rocks from the Nandewais; and nosean, pseudo- 

 leucite, nepheline phonolites, alkaline trachytes and pantellarites, 

 socialite and melilite basalts, &c., from the Warrumbungles. 

 There is also a remarkable porphyritic sill rock from the Nande- 

 wars which may perhaj^s form a new rock-iype. Mr. Jensen 

 expects to have a paper ready by June or July, embracing all 

 his work in the field and laboratory on the Geology of the Nan- 

 dew^ars and Warrumbungle Mountains. I may add that the 

 Council has reappointed Mr. Jensen to a Fellowship. 



In response to the Council's offer of two vacant Linnean 

 Macleaj'^ Fellowships tw^o applications were received, one of which 

 met with the approval of the Council. I have now much pleasure 

 in availing myself of the first opportunity of formally announcing 

 to the Society the name of the second Linnean Maclea}^ Fellow, 

 Mr. James M. Petrie, D.Sc. The particular branch of work which 

 Dr. Petrie will follow is Biochemistry. Dr. Petrie's training 

 has been such as to especially fit him for this line of research. 

 Commencing at the Heriot-Watt Science College, Edinburgh, Dr. 

 Petrie continued his studies at the University of Sydney where 

 he completed a distinguished science course at the end of 1905, 

 Among distinctions gained were first class honours and medal 

 in chemistry at the B.Sc. examination of 1904; Caird Research 

 Scholar in Chemistry (1904); and first class honours and 

 medal in Organic Chemistry at the D.Sc. examination of 1905. 

 Dr. Petrie is highly recommended by his instructors, and has had
