 the coast of Maine, several Salices, Junci, Car/res 2ind grasses. 



As we go farther north, many of these species approach the level of 

 the sea, and most of them have been found in the proper arctic flora, 

 accompanied by many species which are not found on these mountain- 

 tops.

 Prof. Seaman illustrated, by means of slides and the lantern, different 

 phases of fungoid life. The fructification of Erysiphe, the mildew on 

 grape-leaves; Sphczria 7norbosa, the black-knot of plums; Miiconimcedo, 

 common mould; and some of the Oidium family on raspberry and rose 

 ] eaves, were very beautifully exhibited. Also the Saprolegnia or fish- 

 fungus, and the archegonia and antherozoa of Fucus vesiculosus. 



May \oth, i\d,Sth meeting.) 



Dr. Vasey presented the Herbarium some sixty species of grasses 

 found in the vicinity. It was also stated by other members of the club 

 that a large number of specimens illustrating the Flora and Fauna of 

 the District, were ready for presentation, whenever suitable cases shall 

 be in readiness. 



Prof. Chickering called attention to a new locality of Erythronium 

 albidum. Dr. Shaeffer spoke of the coincidence of the first warm days 

 of this season with those of last year, May 9th and loth being the dates 

 in both cases. 



Dr. Gale alluded to the influence of the different poisons on swine. 

 Dr. Curtis spoke of the experiments of a friend, who administered large 

 doses of poison to swine on his premises, but without effect. A dis- 

 cussion then arose on the effect of temperature on mental and physical 

 development. 



Dr. Foreman spoke of the phenomena of cloud formation and dis- 

 persion around mountain tops, where all day long, the vapor is under- 

 going condensation, and yet without any apparent increase in volume. 

 He also mentioned having seen the same phenomenon over the waters 

 of Chesapeake Bay.
