On Tuesday, September 8th, the Section held a joint 

 meeting with I (Physiology) to consider the biological and 

 pathological relations of blood parasites, especially Trypano- 

 somes. R. Newstead contributed an account of the Bionomics 

 of Tsetse flies, while J. B- S. Moore and A. Breinl described 

 some newlj^-discovered features in the life history of the Try- 

 panosoma of sleeping sickness. When the flagellate parasites 

 disappear from the blood they are present as small, non- 

 flagellate cells in the spleen and marrow. Drs- Breinl and 

 Hindle gave a paper on the life history of Piroplasma canis. 

 Besides the ordinary amoeboid and " twinned " forms in blood 

 corpuscles, they detected two flagellate forms — one round, the 

 other oval, in the plasma of the vertebrate host. But they 

 had no results as to the life-C3'cle in the tick. 



A discussion on nomenclature was opened on Fridaj^ 

 morning, 4th September, by Mr. G. A. Boulenger of the 

 British Museum. He protested against the changes, in well- 

 known, classically-used names, that are supposed to be re- 

 quired by the " law of priority." Apparently Mr. Boulenger 

 carried the meeting with him, as a strong resolution on the 

 subject was passed. 



The Section did not meet for business on Saturday, 5th 

 September, but a party of seventy paid an early visit to the 

 Zoological Gardens in Phoenix Park, where the Council 

 of the Royal Zoological Society entertained them at break- 

 fast in the Haughton House. This gathering was generally 

 admitted to have been ver}^ enjoyable, and much interest was 

 afterwards displa3^ed in the fine set of animals on view, 

 especially the three Chimpanzees at present in the Anthropoid 

 House, two well-grown litters of Lion-cubs, and the Pacific 

 Sea I^ions and Irish Grey Seals in their new pond. In the 

 afternoon, by kind invitation of Rev. W. S. Green, a party of 

 zoologists travelled to Kingstown and boarded the new 

 fisheries cruiser *' Helga." The vessel steamed out towards 

 Lambay, and practical demonstration of the admirable gear 

 and apparatus for collecting and preserving marine specimens 



was given.
