retards the action of pepsin, trypsin, and rennet, but is 

 without action on invertine, maltase, and lipasidin. It 

 exerts an antiseptic action on bacilli. — The proportions of 

 chloroform contained in arterial blood during anesthesia 

 and the effects produced : J. Tissot. There appears to be 

 no direct proportion between the amounts of chloroform 

 present in arterial blood and the anaesthetic effects pro- 

 duced. — Contribution to 111" study of the pathologii al 

 anatomy of epithelial cancers of the prostate MM. Mot* 

 and Majewski. Trepanning and ventricular puncture in

 Linnean Society, November 29, 1905. — Mr. T. Steel, 

 president, in the chair. — Further notes on hybridisation in 

 thi gei us Eucalyptus: J. 11. Maiden. This paper briefly 

 recapitulates recent work on the subject, directs attention 

 to the fact that the credit of the discovery of natural 

 hybridisation in this genus belongs to George Caley, whose 

 observations were made in New South Wales before 1810, 

 and indicates the guides which point to a natural hybrid. 

 —Miscellaneous notes (chiefly taxonomic) on Eucalyptus, 

 part ii. : J. II. Maiden. Reasons are given for the con- 

 tention that the blue or Hooded sum of coastal New South 

 Wales (E. saligna, Sm.) cannot in reality be separated 

 from the Bangalay (E. botryoides, Sm.), and the name 

 var. botryoides is proposed for ihe latter. — On an un- 

 described species of Cryptocarya from eastern Australia : 

 R. T. Baker. — Studies on Australian Mollusca, part ix. : 

 C. Hedley. The marine molluscan fauna of New South 

 Wales is enlarged by the addition of new species of 

 Eulimella, Diala, Actseon, Mitromorpha, Rissoa, Bornia, 

 and Cvamiomactra. — Descriptions of three new Australian 

 species of the genus Austrogomphus (Neuroptera : 

 Odonata) : R. J. Tillyard. — (1) A pleomorphic slime-
