Dauglish earned his medical degree at Edinburgh. Having been thoroughly unimpressed by the Scottish bread of the day, he began to make his own, and to study the science associated with the process. When he applied his earlier studies in chemistry to the process of bread making, he determined that it would be possible to produce carbonic acid gas in bread without yeast. He established that if one could instead introduce carbon dioxide to the process—by dissolving it into solution in the water—this would eliminate the need for fermentation, dramatically reduce the need for physical contact with the dough on the part of the workers, and consequently introduce a greater level of cleanliness into the bread-making process. Dauglish sought to abolish manual kneading, which he believed was unclean and unhealthy. Some years later, an 1878 issue of the scientific journal, "Nature", reported:
