cords of wood in twenty-four hours. ‘These chips are conveyed in 
wagons to the boiling-house, and placed in boilers, where the 
reduction to pulp is effected. The pulp thus reduced is then con- 
veyed to pulp-engines, is worked in these engines, and run through 
cleaning machines. From the cleaning machines the pulp is taken 
to the bleaching-house. After haying been bleached, it is then 
ready to be made into paper—in the same way as any other pulp. 
Excellent white printing paper very good for newspapers, and at a 
price of three cents per pound less than is charged for the same 
quality of paper made from rags, is manufactured from this pulp 
by Martin Nixon, at the Flat-rock paper-mills, adjacent to the pulp 
works. The wood-pulp must, however, be mixed with about twenty 
per cent. of straw-pulp, this mixture improving the quality of the 
paper. These works have been so successful, that the price of 
paper for newspapers has declined three cents per pound since they 
have been in operation. ‘This is a very great step in the progress 
of those arts which contribute so greatly to our comfort and 
civilization. 
Enaianp.—At the meeting of the Royal Horticultural Society, 
held on the Ist of May, at South Kensington, Mr. W. G. Smith 
exhibited a fine specimen of Morchella crassipes, Kromb., a species 
entirely new to Britain. This plant is admirably figured by 
Klotzsch in Krombholz’s magnificent work on ‘Fungi.’ It was 
found in red soil by Miss L. E. Lott, at King’s Kerswell, near 
Newton Abbot, Devonshire, at the end of April last. 
Osrruary Noricr.—English science has sustained a severe loss 
in the death of Dr. W. Harvey, F.R.S. and L.S., Professor of 
Botany in Trinity College, Dublin, and well-known by his valuable 
works on ‘ Algz,’ and on the ‘ Botany of South Africa.’ Dr. Harvey 
died on the 15th of May, of phthisis, at Torquay, whither he had 
repaired for the benefit of his health. 
IV. CHEMISTRY. 
(Including the Proceedings of the Chemical Society.) 
But few additions of general and popular interest have been made 
to the knowledge of chemical science since our last publication, M. 
Baudrimont has made some curious experiments illustrating the 
Allotropism of oxygen. It is well known that when hydrochloric 
acid reacts on binoxide of barium, binoxide of hydrogen is pro- 
duced, while by the action of the same acid on binoxide of 
manganese chlorine is set free. It seems clear, then, that chlorine 
has more affinity for barium than for the oxygen that peroxidizes
