242 PROCEEDINGS OF SOCIETIES. 



Mr. Hcnnali, alluding to these photographs of parallel cylindrical 

 rods rotating over other parallel rods, remarked they were intended 

 to show how careful we must be in referring markings to the objects 

 themselves, and not to the mode of illumination, which he believed 

 was the case with some of the markings and " sj)ectral " dots seen and 

 described by Dr. Pigott, 



Mr. Wonfor exhibited Beck's illusive photographs of a small 

 tumbler partly covered with hemispheres, and which appeared, according 

 to the way in which the light fell on them, either hemispherical eleva- 

 tions or hexagonal depressions. In illustration of Mr. Hennah's 

 remarks, he would exhibit a slide in which the fibres in plants crossing 

 each other, produced the illusion of hemispherical dots. 



Mr. Hennah, inquiring whether any gentleman had any special 

 object to exhibit, said he had brought down some slides prepared by 

 l)r. Addison to illustrate the absorption vessels in plants referred to 

 by Herbert Spencer in the Linnean Society's ' Transactions,' and 

 eighteen slides of vegetable hairs prepared from specimens supplied to 

 him by Mr. D'Alquen. 



Mr. 0. Smith said he had brought slides of algfe and lichens to 

 illustrate the moniliform gonidiac layer, common to some species of 

 both lichens and algae, and to which he had referred in his paper 

 " On Lichens." 



Mr. Wonfor then called attention to a method of preparing coal 

 sections described in the last number of the ' Quekett Club Journal,' 

 and said he was prepared to show vegetable scales and hairs and 

 fibro-cellular tissue from different si)ecies of Oncidium, Arides, Pleuro- 

 thallus, &c. 



The meeting then became a conversazione, when, in addition to the 

 objects mentioned above, Mr. Glaisyer exhibited raphides in American 

 aloes, and cuticle of pea in situ. Mr. R. Glaisyer exhibited fern scale 

 and sections of coal showing woody tissues. 



Mr. Hennah showed a ready manner of making a cell for dry 

 objects with a brass ring and electric cement. 



It was determined that the next Microscopical Meeting, March 

 23rd, would be on " Spores." 



March 9th. — Mr. F. Merrifield, President, in the chair. 



Messrs. Marshall Hall and T. Francis, jun., were elected ordinary 

 members. 



Mr. Wonfor announced the receipt of thfe January number of the 

 ' Quekett Club Journal ' from the Secretary, and of eight reprints of 

 papers on microscopical subjects by Dr. G. C. Wallich, from the 

 author. 



Votes of thanks were given to the donors. 



The President then read a paper " On Tree Planting in Brighton — 

 Suggested Improvements," in which, after disproving the oft-made 

 assertion that trees would not grow at Brighton, he called attention 

 to many trees and shrubs other than those which had been already 

 tried which might be got to grow to the manifest improvement of the 

 town. 



In concluding his paper, he said there was something in the cul-
