- The first essential in chemistry is that you should perform practical work and conduct experiments, for he who performs not practical work nor makes experiments will never attain to the least degree of mastery. But you, O my son, do experiment's so that you may acquire knowledge. Scientists delight not in abundance of material; they rejoice only in the excellence of their experimental methods.
