M. HEEMSKERK AZN replies. He tenders thanks for the urbanity observed throughout the discussion. But it is undeniable that his opinion agrees with the existing right and the prevalent ideas in Europe and America. Of course, if revocation is intended, improvement of the law has to be given up. In reply to the Minister, he has no doubt but that the desire for revocation originated in Prussia, but he has said that in Germany the tide has turned in favour of Patents, on the strength of the “Deutsche Industrie Zeitung” and Klosterman’s recent work. The revocation of the Patent-Law may have been contemplated, but the Prussian Government is not now disposed to have the idea carried out. He asks but for what the English equally asked for—_i.e._, a renewed inquiry. What, after all, is foreign experience to the exercise of law in the Netherlands? How does the project tally with the establishment of a new division of industry in the Department for Internal Affairs, the chief occupation of which is the granting of Patents? He will not argue with the Minister on general remarks, but merely on the one relating to the abolition of newspaper stamps. Why has that tax been repealed? If henceforth a larger quantity of paper be covered with print, the tax has most likely been done away with to promote the diffusion of general knowledge. He supposes, however, the Minister will agree with Cicero, who says that fame acquired by means of deeds which are not useful is but vanity. The stamp duty has been repealed in order to be useful. And in the present case, will the Minister deny all benefits to him who does his utmost, so as to be useful? He replies also to the several members who have made speeches; he contradicts M. de Bruyn Kops about a general disposition supposed to exist in France towards revocation of Patent-Laws. Michel Chevalier only has changed his mind, but there is no opinion prevailing against Patents. Quite recently both Joseph Garnier and Wolowski have refuted Chevalier’s arguments.
