Sentence:  If I adhered to the system of <WSD>caveats</WSD>, which would throw it upon an individual to be cautious, and to look out lest he should not have notice, if he did not enter a <WSD>caveat</WSD> I would require him to specify in respect of what he entered his <WSD>caveat</WSD>. General <WSD>caveats</WSD>, I think, should not be allowed against all the world and against general inventions, for the same reasons that I would not allow a person to have a patent for a general title without specifying upon what improvements he applied for a patent. 
Meaning of the word marked with <WSD> tags:  A formal objection.
