In support of this theory the defendant's machine was stopped while being operated, and a length of paper extending throughout the «lements of the prooess was eut out and marked with cri)s3-iine8, showiug the successive parts of it corresponding with the successsxve parts of the machine. This length of paper is produced. It is claimed that this exhibit shows that the wax came through the paper and appeared on the opposite surface of it while it was on the waxing cylin- der. In connection with the foregoing views, it is contended for the defendant that the blocks of wood, J, J, are plaeed on the paper solely to keep it in contact with the heated plate, F; that they are not heated and do not become hot, but simply warm, and can be handled with perfect comfort ; that a small piece of solid paraffine allowed to remain on the side of the weights exposed to the plate did not melt, while a small piece of it plaeed on the plate melted atmost instantaneously ; that, as far as concerns the blocks, J, J, the plate is the source of beat; and that the blocks do not and cannot diffuse beat towards the paper and the plate. In regard to claim 5 of the re-issue, the defendant contends that he does not beat bis paper from the opposite side, and ��� �
