four nuclei and sometimes the remains of the axostyles. The 

 cysts give rise to two small flagellates when ingested with coii- 

 tamiiiated water or food by a new host. The flagellates attach 

 themselves by the sucking-disc to the intestinal epithelium, 

 ])afticularly of the duodenum. After a tiute they contract, their 

 flagella are witlidrawn and disajjpear, and the resistant encysted 

 forms, as exhibited, are produced. JSimilar parasites occur in rats 

 and allied rodents, and it is very probable tliat these Protozoa can 

 pass from rats to man by way of food contaminated with fyecal 

 matter from the rodents. Eats constitute a great nuisance in 

 the trenches in Flanders. Many other cases of lambliasis have 

 been observed in Gallipoli, aud in soldiers invalided therefrom. 

 Careful watch should be made for recurrences of lauibliusis among 

 convalescents. 



A discussion followed, in which the following took part : — 

 Prof. Aldo Castellani, M.D. (visitor), Dr. A. P. Young, Miss 

 Carson, Di". Louis W. Sainbon (visitor), and the Px'esident. 



In the absence of the author, Dr. Gilchrist's paper on Jasus 

 lalaadii (Milne Edwards) was epitomised by the liev. T. E. E. 

 iSTEBBiNG, with occasional comments. 



A paper by Mr. B. Millakd Griffiths, M.Sc, comnnuiicated 

 by Prof. G. 8. AV'est, P.L.IS., was briefly explained by the Botanical 

 Secretary, its title being " The August Heleoplaukton of some 

 North Worcestershire Pools." 



Dr. Stapf spoke on the distribution of the Box, Buxus scmjier- 

 virens, Linn., and esjjecially on the relation existing between the 

 English stations and iis area on the Continent, supporting his 

 rei)iarks by lantern-slides (distribution-map and views of Box on 

 Boxhill and in the Chilterns, tlie latter taken by Mr. John 

 Hutchinson). He pointed out that he adopted Dr. Christ's views 

 as to the character of the Box as a relict of the Tertiary flora of 

 Southern Europe, and the discontinuous distribution as brought 

 about by disintegration of an old continuous and much larger 

 area. But he could not share his view that the isolated stations 

 in AV^estern Prance are generally due to old plantations around 

 castles and mona>teries. He considered them like the English 

 stations as relict stations. He finally expressed a wish that 

 these should be more thoroughly studied than has been hitherto, 

 and carefully preserved as far as possible. 



The discussion which followed was engaged in by Dr. A. P. 

 Toung, Mr. T. A. Sprague, i\lr. P. N. Williams, Mr. J. C. 

 Shenstone, Mr. T. Ji. Dyiues, and Mr. C. E. Sahuon, Dr. Stapf 

 replying.
