When I invented the chemical printing afterward, I held that a stone roller could be used for this work as well as a wooden one. I had too little knowledge of the industry at that time and believed that cotton print was done with oil-colors; for I thought that water-colors would wash out. I was a complete stranger to this work. Therefore, I drew a pretty cotton pattern on a stone plate and printed from it with oil varnish and finely pulverized indigo. The impressions turned out very handsome, so that I considered the matter settled and made no further experiments. I imparted this idea to Herr Andre, who saw its importance at once and determined to obtain a patent for it specially. However, we had much to learn. As soon as he arrived in England he discovered that rollers with the design on them were in general use in England. So I had imagined mistakenly that my invention was new. However, printing from stone was in itself valuable for a patent, but Herr Andre unfortunately received the incorrect information that the inventor himself must appear in England, and he decided to send me there. I did not care to go; firstly, because I was vexed at the failure of my hopes in regard to cotton-printing; and secondly, because I wished to go to Vienna. However, I yielded to his representations, and within a few weeks journeyed to London with one of his brothers who spoke English. We went through Hamburg to Cuxhafen and thence in an English packet-boat to Yarmouth, where we landed after a six days' stormy passage. My sojourn in London did not achieve its purpose, which was to establish printing from stone. The exaggerated caution and precision of Herr Philip Andre, who had been named as the man who was to manage the London negotiations, caused a waste of seven months, during which nothing was done to reach our object. We lived with Herr Philip and he kept me at home most of the time, for fear that I might betray our purpose, in which case some speculative spirit might take out a patent before us and then compel us to buy him off for some heavy sum. He did not reflect that a mere declaration is not sufficient in England, but that an exact description of a process must be deposited with the Patent Office.
