DUBLIN MICROSCOPICAL CLUB. 
May 9.— The Club met at Leinster House, Dr. R. F. Scharff (Presi- 
dent) in the chair. 
Prof. Henry H. Dixon showed sections of the anthers of Lilium 
Mariagon, illustrating the various phases of heterotypic mitosis in the 
pollen-mot her-cells. 
L- B. Smyth exhibited seedling of Dtosera rotundifolia, showing linear 
seed-leaves, and the first foliage leaf with large glands. 
Dr. G. H. PethybridgK exhibited a series of photomicrographs, in 
the form of lantern slides, of plant tissues, and called attention to the 
superiority of photomicrographs to the ordinary wall diagrams for use 
in teaching. The slides were arranged in a specially devised frame with 
grooved bars permitting the easy interchange of slides, and provided 
with a transparent but matt background against which the slides are 
viewed by transmitted light. 
David M'Ardi^E exhibited Lejetinea Jlava, Swartz, bearing the pear- 
shaped perianths and autheridia. The specimens were collected on 
Lambay, Co. Dublin, on 14th April last, and are typical when com- 
pared with South American specimens. This locality marks the second 
station for this rare liverwort in the Co. Dublin, it having been found in 
Howth demesne in 1897. Its geographical distribution is interesting; it 
is found in South America, Rio Janeiro, Cuba, &c. For comparison Lejeunea 
HoUii was shown, which is also a remarkable plant, and differs from 
every other Lejeunea in having the female flowers borne on short 
branches which put forth no subfloral innovations, and in all the world 
has only been fouud in Co. Kerry. The specimens exhibited were col- 
lected at Anascaul, near Dingle, in May, 1894. 
W. F. GuNN showed a longitudinal tangential section of the wood of 
the common fig, Fiais carica, under polarized light. The use of a selenite
