346 Notes and Comments. 
for the speeches, and the thanks for the votes of thanks. We 
hope, however, to see the collection soon. From the daily 
press we gather that the new museum has been very much 
appreciated by the public. We trust that the Corporation will 
now turn its attention to the natural history museum. At 
present it is a disgrace to Bradford. 
PRESERVING PLANTS. 
In the Musewns Journal for July, Dr. Fothergill describes 
a method of preserving plants with their natural colour. Dr. 
Fothergill employs sheets ot absorbent cotton wool, placed in 
three layers forming two compartments between two ‘ grids,” 
which are made of a ‘ wire mesh-work of half-inch squares. 
with a heavy encircling band.’ The necessary pressure is 
obtained by fastening one or two straps, preferably of webbing, 
around the grids, and tightening them as required. The 
flowers to be pressed, having been placed in the grid, are then 
suspended in front of a fire, or in the sun, when this is sufficiently 
powertul. The explanation of the success of the method is 
that the process of drying is so rapid that the pigment is fixed 
instead of being slowly decomposed. 
EARTH MOVEMENTS IN SHEFFIELD. 
Professor Wm. G. Fearnsides has kindly favoured us with 
a copy of his paper on ‘Some Effects of Earth Movement on 
the Coal Measures of the Sheffield District (South Yorkshire 
and the neighbouring parts of West Yorkshire, Derbyshire 
and Nottinghamshire), part 1, recently read to the Institute 
of Mining Engineers. In this he states, ‘it is clear that in 
recent years the current view among workers in our district 
has been that ‘ rock-faults,’ ‘ washes,’ and ‘ wash-outs’ are 
occurrences caused by some sort of stream action during 
Coal Measures time. Possibly, as Prof. Kendall suggests, two 
kinds (the contemporaneous-erosion and the tectonic) may 
exist side by side, but, so far as the writer’s own experience 
has extended, he has visited no single example which he can 
accept as belonging to the contemporaneous-erosion class. He 
‘has not evidence enough to allow him to dogmatise, but he 
proposes to state a case for the view that the majority of the 
rock-faults which occur in our own district, as well as the much 
more frequent examples of rock-rolls which locally come down 
on to the coal and displace the usual bind or ‘ clod’ in the 
roof of seams which are subject to rock-faults and wash-outs, 
have been brought about by horizontal earth-movements due 
to lateral pressure at a time when the deposition of the measures 
which contain the coal-seams had been already completed. 
THE VASCULUM. 
No. 2 of this journal, dated August, has reached us. It 
contains an article on ‘ Winter and Summer at Budle,’ by Mr. 
Naturalist,
