SEPARATE INVENTIONS CANNOT BE CLAIMED IN ONE APPLICATION.-Two or more separate inventions cannot be claimed in one application, nor patented in one patent, unless they are so dependent of and connected with each as to be necessarily taken together to obtain the end. sought for by the inventor; and in this latter case the Commissioner of Patents is the judge as to whether or not the pretensions of the applicant are founded in fact and reason. (Ib.)

214. PROTEST.-The filing of a protest against the issuing of a patent shall not be taken in itself as a sufficient reason to withhold the granting of such patent to an applicant. (Ib.)

215. CASES OF DOUBT.-In cases of doubt, and in accordance with the letter and meaning of the law, patents may be issued for an invention already patented, a trial before a judicial tribunal being in such cases the only means of discovering who is the real or first inventor.

216. CAVEAT.—A caveat must be composed of a specification, (and drawings,) and as long as it remains uninterfered with, and that the filer is not called upon to lodge his application in due form on account of an interfering application, the said proprietor thereof can lodge with it additional papers, provided these papers are relevant exclusively to the perfecting of the same invention in progress of completion. (Ib.)

217. INTRICATE CASES.-All cases connected with the intricate and multifarious proceedings issuing from the working of a law of patents of invention, which are not specially defined and provided for in these rules, shall be decided, in accordance with the merits of each case, by authority of the Commissioner of Patents, and the decision shall be communicated to the interested parties through the departmental correspondent of the Patent Office. (Ib.)

218. GENERAL REMARKS.-The correspondence with the department is carried through the Canadian mail free of postage. The forwarding of any paper should always be accompanied by a letter, and a separate letter should be written in relation to each distinct subject.

It is particularly recommended that reference should be made to the law before writing on any subject to the department, in order to avoid unnecessary explanations and useless loss of time and labor; and it is also recommended in every case to have the papers and drawings prepared by a competent person, for the interest both of the applicant and of the public service.

A sufficient margin should be left on paper, and especially on specifications and assignments, for the insertion of references or certificates and for the affixing of the seal thereto.

Although it is optional for the applicant to annex drawings to the specification of a caveat or not, still it is important in the party always to attach drawings to the said specification.

It must be remembered, that the better papers are executed the sooner the work is dispatched at the office,

and the surer the regularity of the proceedings is guarantied.

It must be remembered, when drawing the petition for a patent of inventions, that if a change in the residence mentioned has taken place during the year next to the date of the petition, the change or changes should be mentioned, in accordance with the twelfth section of the patent act of 1869.
