General observations by a judge or a court, in deciding a case, must always be read in view of the facts of the case that waa sub judiee, and are not necessarily authoritative, ex vi termini, in another case where the facts are not the same, although entitled to consideration, as are the views of a text-writer of experience and repute. This case of RusseU v.

The supi'eme court held that the processes de- scribed in ihe original had no connection vrith the compounds patented in the re-issues; that they were not processes for making thoso compounds ; that, in describing the processes, the compounds were not mentioned; and that the invention of the one did not involve the invention of the other. �In Bail V. Langles, 18 0. G. 1405, recently decided by the supreme court, the original specifications and drawings showed an oven so constructed that the products of com- bustion did not and could not pass directly into it. In the re-issue the oven was made a part of the passage-way for the products of combustion, and it was held bad. �In the present case the original specification describes the ��� �
