xxii Proceedings. 



April 22,71(1. — " Demonstration of the Anatomy of the Sheep's 

 Heart," by Dr. Franldin Parsons, who very clearly explained 

 the action of the valves and muscular structure. 



May 21th. — Photography : interchange of information on 

 methods of development, printing, &c. 



Oct. 28(/i. — " Illumination of Microscopical Objects." A very 

 good meeting. The various methods of illumination were 

 discussed and demonstrated. Mr. Low Barjeant taking the chief 

 share in the proceedings. He explained how to arrange the 

 lamp and mirror, in order to obtain a parallel central beam of 

 light, and also how to test the light to show that the adjustment 

 is correct. The various ways of using the bull's-eye condenser, 

 and especially how to obtain a black ground illumination for 

 medium and low powers, quite equal to that obtained by the 

 Webster or other achromatic condensers were explained, Mr. 

 Low Sarjeant's principal object being to show that excellent 

 illumination can be obtained without the use of expensive 

 apparatus. 



The field meetings of the year have been as follows : 



The first was on Whit Monday, to Oxted, Woldingham and 

 Limpsfield. The day unfortunately was very stormy, in spite of 

 which a party of nearly twenty assembled. 



Oxted Church was first visited ; the high downs beyond were 

 then climbed. The orchids which abound in the woods and 

 banks by the way were but just appearing. On the top of the 

 downs a gale of wind with driving rain was encountered. The 

 little church of Woldingham offered some shelter to the party, 

 and lunch was partaken of beneath its protecting walls. 



The plantations on the downs were full of spring flowers in 

 the richest profusion and beauty, and the botanists were gratified 

 by the sight of blue sheets of the lovely wood forget-me-not, 

 Mijosotis sijlvatica, a scarce and very local plant in the South of 

 England ; and it was their unanimous opinion that they had 

 never seen the blue-bell in such luxuriant profusion. A very 

 robust form, with long leaf-like floral bracts, was noticed. 



On a fine day the excursion would have been a most attractive 

 one. The views from the North Downs, which here attain their 

 highest elevation of about 880 feet, are most commanding and 

 extensive. The churches of Oxted, Woldingham and Limpsfield 

 present many features of interest to the archaeologist, and the 

 botanist, entomologist, and geologist would alike find much to 

 interest him. 



On June 27th the excursion in conjunction with the Geo- 

 logists' Association was to East Griusted and West Hoathley, 

 and the party had the advantage of the guidance and direction 

 of Mr. Topley, President of the Association, and Mr. Ed. Easton. 

 It was chiefly occupied with the geological features of the county.
