A paper by Mr. Arthur William Abaters, F.L.S., F.G.S., 



entitled " Soiiie Collections of the littoral JNJariiie I'auna of the 

 Cape Verde Islands made by Cyril Crosslaud, M.A., B.Sc, P.Z.S., 

 in the summer of 1904 — Bryozoa," was read in title. 



Dr. George Henderson, F.L.S., sent for exhibition three 

 seedless pears, from a tree which practically produces no seeds ; 

 it is about 25 years old, and usually flowers twice — once very 

 early in the season, and again two months later, both sets o£ 

 flowers producing fruit, but the later ones often do not ripen. 

 Dr. Henderson compared these pears with the cultivated plantain, 

 but the (Smyrna flg, of vvliich lie grows four varieiies, does not 

 ripen fruit unless at least one flower is fertilized by pollen from 

 the wild flji'.

 Anatomy of some Compositse,"' which was communicated by 

 Prof. M. C. Potter, F.L.S. 



Mr. Small theji gave a demonstration of " "Wind dispersal 

 Apparatus," and described it thus : — 



The purpose of the apparatus is to determine the exact velocity 

 of the wind required to blow the fruits of the Composite a 

 sufficient distance to secui'e proper dispersal. The apparatus 

 consists of an electric fan (the speed of which can be varied), 

 a long, wide glass tube, and an anemometer. The anemometer 

 consists of a beam with a disc attached, upon which the wind 

 impinges, and a scale-pan slung over a pulley, the whole forming 

 a niechanical couple. The pressure is measured by this instrument 

 and converted into miles per hour. 



The tube is moved away from the fan until the fruits are
