and the whole left for five days, except that it was occasionally 
pumped up to maintain the pressure, which dropped rather rapidly ; 
in fact, on several occasions, namely at night, there can have been 
no pressure at all for some hours, as it was always necessary to have 
recourse to the bicycle pump in the morning. On being taken out 
after five days, the wood was found to be much harder, or rather, it 
was tough—I could make no impression on the wood by scratching 
with my finger-nail, but it had a hard /eathery feeling when scratched. 
It was now allowed to dry by simple exposure to the air in my 
workshop, and in six days more appeared to be dry. 
I should add that before hardening it as above described I had 
managed to cut one end of the wood flat, across the grain. The 
wood being dry, I now attempted to polish it by simple rubbing 
against a soft cloth, and obtained a fair polish, but, not having the 
necessary apparatus or skill to cut a section, I gave the specimen to 
the British Museum of Natural History, where it now is. Hoping 
that this description may be of use to others.

WILLIAM SMITH’S MAPS. 
Srr,—I am preparing a monograph on Smith’s maps, ete., for the 
Yorkshire Geological Society, and am anxious to see a ‘‘ Reduction of 
Smith’s large Geological Map of England and Wales intended as an 
‘elementary map for those commencing the study of Geology, 1819”, 
referred to in Phillips’s Memoirs of Smith. 
- I find that Smith’s large maps of 1815 often bear a signature and 
a number, such as ‘‘ No. 66” or ‘‘a 33”. If any readers of the 
GxrotocicaL Macazrinz possess copies of this large map, perhaps they 
would kindly inform me what number the map bears. It occurs 
under the ‘‘ Section of Strata”, which appears on the map to the east 
of the Humber estuary.

Count Sotms-LavsacH was well known amongst men of science as 
a most distinguished botanist. His death was communicated to this 
country by Professor A. G. Nathorst, the Swedish Paleontologist of 
Stockholm. 
Count Solms was born in 1842, and was in his 73rd year. He 
devoted his life wholly to science. He was Professor of Botany at 
Gottingen and afterwards at. Strasburg, from which he retired a few
