280 THE JOURNAL OF BOTANY 
begun with a small initial. We note that this part is styled 
“Vol. iv. sect. 2, part ii.,” whereas its predecessor was simply 
“Vol. iv. sect. ii.” : we gather a this that, owing to some mis- 
calculation, vol. iv. will really be two volumes bearing sectional 
numbers—an inconyenience one cannot fail to cause much con- 
fusion in citation and referen 
WE live and learn. Mr. 0. J. Cornish’s recent biography of 
Sir William Henry Flower contains the following paragraph 
p. 184-5) on the Department of Bota i :—“In the Botanical 
Department was the herbarium of Sir Hans Sloane, containing 
specimens; the great botanical collection of Sir Joseph 
Banks ; and William Wilson's herbarium of British and foreign 
specimens, containing the identical hinnte from which the ea 
descriptions made by Lin neus, Amblett, Jagny, Brown, an 
entham were written.’ This summary of the contents of Wilson’ 8 
herbarium will astonish botanists, who may also be — for 
ignorance of the work of ‘‘ Amblett”’ and ‘ ‘Jagny’’; we can only 
conjecture that these names, hitherto unknown to fame, —— 
respectively ‘ Aublet” and ‘‘Jacquin.” Considering Sir Willia 
intimate connection with the Museum, it seems strange that 
Cornish did not submit his proofs to some one acquainted with its 
contents, 
Messrs. George T. Moors — a F. Kellerman describe 
‘*a method of destooying or preven the growth of Alge and 
certain pathogenic Bacteria in porn supplies” (U.S. Dept. of 
Agriculture, Bulletin No. 64, Washington, 1904, 44 pp.), which is 
likely to find its uses in this country. ‘It has been found that 
copper sulphate in a dilution so great as to be colorless, tasteless, 
and harmless to ana; t - gpm toxic to the alge to destroy or 
prevent their appeara The mode of application makes this 
method applicable ie ener votre of all kinds, pleasure ponds and 
lakes, fish-ponds, oyster-beds, watercress-beds, ete. t is also 
probable that the shedhiod can be used for the destruction of 
mosquito larve. At ordinary temperatures 1 part of copper sul- 
phate to 100,000 parts of water destroys typhoid and cholera germs 
in from three to four hours. The ease with which the sulphate 
can then be eliminated from the water seems to offer a practical 
method of sterilizing large bodies of water, when this becomes 
necessary.” All traces is copper seem - disappear from the water 
within twenty-four hours. Though fatal to alge, infusoria, and 
the bacteria of disease, ‘She treat eke sppeais to leave the sapro- 
a and harmless bacteria unaffected.—A. G. 
. C. Warnstorr, the distinguished sphagnologist, has just 
scat ‘his third et ee to the Kryptogamenflora der Mark 
Brandenburg (Band ii. 1, Laubmoose, Leipzig, 1904. 240 pp., with 
fi e first volume contained the hepatics and sphagna; the 
present et is concerned principally with the cleistocarpous genera 
of the mosses, and the tribes Weisiee, Dicranee, Pottiee, and 
Trichostomeea. The descriptions are adequate, are carefully written, 
are accompanied by keys to the orders, tribes, genera, and 
species.—-A. G. _
