124 THE MICROSCOPICAL NEWS. 
these Aicidia he produced Uredines as in 1881, but his method of 
isolating the trial plants was more perfect, and no Uredines were 
developed on uninfected specimens. Other experiments were 
made with various forms of Uredo, all tending to the same result, 
and Mr. Plowright is now perfectly convinced that Aicidium and 
Puccinia are different forms of the same fungus. 
MANCHESTER CRYpPTOGAMIC SociETy. —The usual monthly 
meeting was held in the Old Town Hall, Dr. B. Carrington, F.R.S.E., 
in the chair, Mr. W. H. Pearson exhibited a specimen copy of 
the Fasciculus III. of the He epatice Britannie Exicate, contain- 
ing many new and rare species, amongst which were noticed 
Marsupella Stableri, Cephalozia Francisci, C. eraria, C. Turneri, 
Bazzanta trilobata, Lepidozia Pearsont. 
Dr. J. B. Wood sent specimens of the two species of Buxbaumia, 
B. indusiata and B. aphylla, both gathered by himself in the same 
locality during his visit to the Vosges, Aug. 1872. The B. indusiata 
growing on rotten wood—the Z. aphylla on the ground. He also 
sent specimens of Dichelyma capillaceum in fruit, from Norway and 
North America. 
PostaL MicroscopicaL SociETy.—The Journal of this Society 
for March commences the second volume. Its price, we notice, 
has been raised to eighteenpence, which is not too dear for an 8vo 
64 page journal, illustrated with 6 plates. Respecting the cha- 
racter of these plates, we must candidly confess we do not like 
them,—would it not be better to give only 2 plates in each number 
and have them done well, rather than 6 of a not altogether satis- 
factory character? We notice the numbering of the plates has been 
continued from vol. 1. This is a mistake, each volume should be 
complete in itself. 
OTHER JOURNALS.—While on this subject may we venture an 
appeal to the Council of the Royal Microscopical Society? The 
first volume is dated 1878 and called Vol. I. ; the 1879 vol. is 
inscribed Vol. II., and 1880 Vol. III. Then in 1881 the title 
page bears the inscription Series II., Vol. I., and the next year 
Series II., Vol. II., the 1883 volume will probably be Series IL., 
Vol. III., ’so that during the past six years we shall have had two 
inscribed Vol. I., two Vol. II, and two Vol. III. We hope these 
remarks will not encourage any one to prepare Series III., Vol. I. 
A further suggestion may be thrown out to the effect that if the 
Journal grows any thicker it would be well to divide it into half- 
yearly volumes. 
GELATINE AND ALBUMEN P.ates.—Mr. J. T. Chapman, of 
Manchester, is now supplying these plates for the production of 
transparencies for the lantern. ‘They are about as sensitive as wet 
plates, and produce exceedingly good pictures when developed 
with ferrous oxalate.
