Ttie Minutes of tlie General Meeting of the 16tli December, 

 ID 15, were read and conlirmed. 



Mrs. Elsie AVilliins Sexton was proposed as a Fellow.

Mr. Miller, Christy, E.L.S., i-ead a paper " On the Definition 

 of ' Eight ' and ' Left ' in relation to coiled, rolled, revolving, and 

 similar objects : a Problem in Scientific Terminology," \a Inch was 

 illustrated by specimeus, models, and lantern-slides. Tie referred 

 to such terms as " i-igbt " and "left," following or against the 

 sun (in northern latitudes), "clock-wise" and "counter clock- 

 wise," as used by biologists, and also cited terms used by 

 mathematicians which could not be used by naturalists with any 

 advantage. He advocated the usage postulated by Linngeus, in 

 his 'Philosophia botanica,' p. 103, before he became confused and 

 altered his definition to an ai)surdity, and recommended the use 

 of the heraldic words "dextral" and " sinistral" as unambiguous 

 terms. 



Dr. Rendle, Mrs. Longstaff, Mr. II. N. Dixon, and Mr. F. N. 

 "Williams took part in the discussion which followed, and the 

 author replied. 



Mr. Horace W. Moncktox, Treas. and V.-P., gave a com- 

 munication on " Some Aspects of the Elora of the Eagshot 

 District," illustrating it by specimens and lantern-slides of the 

 scenery. 



He stated : — This communication deals with the area occupied 

 by the Geological Eormation known as "The Main Mass of the 

 Eagshot Sands." About half is in Surrey, the remainder being 

 nearly equally divided between Berkshire and Hampshire. The 

 more important places in the district are Wokinghau), Ascot, 

 Yately, Sandhurst, Eagshot, Chobham, Weybridge, Camberley, 

 AVinchfield, Earnborough, and Aldershot. The greater part Mas 

 until recent times a tract of pine-woods, heaths, and peaty swamps, 

 and its character was mainly due to the sandy nature of the 

 Eagshot Eormation and the gravels resting upon it. There is no 

 lime in these strata and, though clay occurs in places, the soil is 

 markedly different from that on the London Clay, which comes 

 to the surface around the Eagshot district. 



The flora of much of the area resembles that of the Oak-Eirch- 

 Heath Association (• Types of British Vegetation,' ed. by A. G.
