He vacillates in his account of hypotheticals and disjunctives. His final opinion is given (Vol. II., 370-378 -- " Hypotheticals (conjunctive and disjunctive), April 30, 1849"). "These syllogisms appear to be only modifications or corruptions of certain immediate inferences, for they have only two terms, and obtain a third proposition only by placing the general rule of inference (stating, of course, the possible alternatives), disguised, it is true, as the major premises.英文原著 · 《The Scottish Philosophy》

Not to work in a circle, we select an important group which has not served as a basis for the reconstruction of bridges; and it must be a group which we feel justified in assuming to be old enough to have availed itself of ancient land-connections.英文原著 · 《Darwin and Modern Science》
To return to the colder scientific aspect of chemistry. It has shown us how bodies stand affected to each other through an almost boundless range of combinations. It has given us a most ingenious theory to account for certain fixed relations in these combinations. It has successfully eliminated a great number of proximate compounds, more or less stable, from organic structures. It has invented others which form the basis of long series of well-known composite substances. In fact, we are perhaps becoming overburdened with our list of proximate principles, demonstrated and hypothetical.英文原著 · 《Medical Essays》
The phenomena of isomerism, or identity of composition and proportions of constituents with difference of qualities, and of isomorphism, or identity of form in crystals which have one element substituted for another, were equally surprises to science; and although the mechanism by which they are brought about can be to a certain extent explained by a reference to the hypothetical atoms of which the elements are constituted, yet this is only turning the difficulty into a fraction with an infinitesimal denominator and an infinite numerator.英文原著 · 《Medical Essays》
