Success or failure in mechanical de-vices, requiring such nice adjustment, and subject-ed to so many contrary influences, he says, may de-pend upon some apparently trifling alteration in thestructure; but, if the required alteration has goneunheeded, through years of constant demand for itsdisclosure, he goes on to state that he can see noreason why the person fortunate euough to finallyhit upon it should not lie given the benefits of an in-ventor.
