The applicent, according to his assertion, is working in a new field. He should not rely on his bare assertion as to the facts. He should acquaint the Office with such experiments as ne may have made which substantiate the facts. As to the question of the height to which the terminals must be raised, attention is called to the fact that applicant gives no definite information with respect thereto in his spacification. His specification is quite in the air in this regard. It would warrant the Examiner in rejecting the claims as being based upon an insufficient specification. The appli cant states that the terminels must be raised high enough so as to permit the electricity to pass by conduction with the pressures used. But as this is a new art the average electrical engineer is not supposed to know what these heights and pressures are. plicant need hev e no fear that the Examiner is desirous of limiting him to any given neight. All heights which come within the field of conveying the electrical energy by conduction under the pressures employed will fall within the invention. cific height and some specific pressure must be given for the information of the public. Otherwise experiment will be necessary The apBut some spe
