(_e_) As can sometimes be demonstrated by analysis, the dropping of objects or the overturning and breaking of the same are very frequently utilized as the expression of unconscious streams of thought, but more often they serve to represent the superstitious or odd significances connected therewith in popular sayings. The meanings attached to the spilling of salt, the overturning of a wineglass, the sticking of a knife dropped to the floor, and so on, are well known. I shall discuss later the right to investigate such superstitious interpretations; here I shall simply observe that the individual awkward acts do not by any means always have the same meaning, but, depending on the circumstances, they serve to represent now this or that purpose. Recently we passed through a period in my house during which an unusual number of glass and china dishes were broken. I myself largely contributed to this damage. This little endemic was readily explained by the fact that it preceded the public betrothal of my eldest daughter. On such festivities it is customary to break some dishes and utter at the same time some felicitating expression. This custom may signify a sacrifice or express any other symbolic sense. When servants destroy fragile objects through dropping them, we certainly do not think in the first place of a psychologic motive for it; still, some obscure motives are not improbable even here. Nothing lies farther from the uneducated than the appreciation of art and works of art. Our servants are dominated by a foolish hostility against these productions, especially when the objects, whose worth they do not realize, become a source of a great deal of work for them. On the other hand, persons of the same education and origin employed in scientific institutions often distinguish themselves by great dexterity and reliability in the handling of delicate objects, as soon as they begin to identify themselves with their masters and consider themselves an essential part of the staff. I shall here add the report of a young mechanical engineer, which gives some insight into the mechanism of damaging things. “Some time ago I worked with many others in the laboratory of the High School on a series of complicated experiments on the subject of elasticity. It was a work that we undertook of our own volition, but it turned out that it took up more of our time than we expected. One day, while going to the laboratory with F., he complained of losing so much time, especially on this day, when he had so many other things to do at home. I could only agree with him, and he added half jokingly, alluding to an incident of the previous week: ‘Let us hope that the machine will refuse to work, so that we can interrupt the experiment and go home earlier.’
