Live-box with Micrometer Scale engraved on the lower j^. j j m Cooper Webb. 



glass tablet, by Andrew Pritchard / 



Mr. C. F. Rousselet said that the live-box presented to the Society 

 that evening was one made by Andrew Pritchard about 1846. It had 

 a micrometer scale engraved on the bottom glass tablet, the idea being 

 to enable an object placed in it to be measured, or at least its size esti- 

 mated when observed, though he thought this would not be very easy 

 to accomplish in the case of an object which kept moving about. The 

 live-box would be a valuable addition to their collection of instruments 

 and apparatus. 



The President, in introducing a paper by Miss S. L. M. Summers, 

 M.A., B.Sc, " On Antipatharians from the Indian Ocean," said that it 

 was a coincidence that led him again to ask the attention of the Society 

 to the group of animals that he had discussed at the last Meeting — the 

 Antipatharians, or " Black Corals." The paper he had to submit was 

 by one of his assistants, and described a collection made by two of his 

 students, Mr. R. N. Rudmose-Brown, D.Sc, and Mr. J. J. Simpson, 

 M.A., B.Sc, in the Mergui Archipelago and off Ibo in Portuguese East 

 Africa. It included fourteen species of which three were new, and it 

 threw some light on a number of species which had been previously 

 described from axes without polyps. After referring to the variety of 

 form among Antipatharian colonies, to the characteristic spinose axis of 

 which fourteen examples — very similar at first sight — were shown under 

 Microscopes on the table, to the structure of the polyps, which was illus- 

 trated by coloured diagrams and by cross-sections under the Microscopes, 

 and to the affinities of the group, which are apparently with the sea- 

 anemones, but must remain somewhat uncertain until the embryonic 

 development is discovered, the President read a portion of the paper, 

 and complimented the author on her terse and precise descriptions of 

 species.
