WOOD PULP FOR PAPER. 123 
paper-manufactory was in full operation at the town, of Rievi, in Italy, 
and enjoyed a world-wide reputation at the time ; but with the death of 
its proprietor the secret seems to have lapsed into oblivion. The mani- 
fold attempts subsequently made to continue the manufacture were 
always baffled by the difficulty of removing the silicious, resinous, and 
glutinous matters contained in the blade. 
The recovery of this process has at last been effected, and is due to 
the research of one Herr Moritz Diamant, a Jewish writing-master in 
Austria. Having busied himself for some time in experiments on 
Indian corn, the ingenious discoverer has at length been rewarded with 
the desired results of his labour ; and a trial of his method on a grand 
scale, which was made at the Imperial manufactory of Schiogelmuhle, 
near Glegnitz (Lower Austria), has completely demonstrated the cer- 
tainty of the invention. Although the machinery, arranged as it was 
for the manufacture of rag paper, could not, of course, fully answer the- 
requirements of Herr Diamant, the results of the essay were extremely 
favourable. The article produced was of a purity of texture and white- 
ness of colour that left nothing to be desired ; and this is all the more 
valuable from the difficulty usually experienced in the removal of the 
impurities from the rags. Knots, and other inequalities of surface, 
so frequent in the ordinary paper, and which give so much trouble 
in printing, the new product is entirely free from, and this- without 
the material undergoing any special process to attain the desired 
end. 
Another great advantage, and this in an economical point of view, is 
the reduction of the steam power required in the manufacture by one- 
third of its present amount, in consequence of the material being re- 
duced to pulp by chemical, and not, as at present, mechanical agency. 
The present proprietor of the invention is Count Carl Octavio Lippe,. of 
Wessenfold, who has bought it •from the originator, and from several 
experiments deduced the following results : — 
1. It is not only possible to produce every variety of paper from the 
blades of Indian corn, but the product is equal, and in some cases even 
superior, to the article manufactured from rags. 
2. The paper requires but very little size to render it fit for writing 
purposes, as the pulp naturally contains a large proportion of that 
necessary ingredient, which can at the same time be easily eliminated if 
desirable. 
3. The bleaching is effected by a very rapid and facile process, and, 
indeed, for the common light-coloured packing-paper, the process be- 
comes entirely unnecessary. 
4. The Indian corn paper possesses greater strength and tenacity 
than rag-paper, without the drawback of brittleness, so conspicuous in 
the common straw products. 
5. No machinery being required in the manufacture of this paper
