The Herb Pantagruelion hath a little Root somewhat hard and ruff, roundish, terminating in an obtuse and very blunt Point, and having some of its Veins, Strings or Filaments coloured with some spots of white, […]

If you put foure Spleets in a Hiue, then cut their backes, where they must leane one against another, to square angles, such as be foure in a circle: if but three, cut them to obtuse angles, such as are three in a circle: (you may readily try them, before you put them in, by Moulds made iust to those formes) and so will they stand close and firme together.

More-over, as the Buildings Ambligon / May more receive then Mansions Oxigon / (Because th' acute, and the rect-Angles too, / Stride not so wide as obtuse Angles doe) / So doth the Circle in his Circuit span / More room then any other Figure can.

Obtuse angles of the through crossing. — The system of the two obtuse-angled points is especially termed the dead-crossing. […] The point itself, less liable to damage than that of the crossing proper, on account of its obtuse form and its position relatively to the wheels, acts the same part towards the tapered portion of the cut rail, as the wing-rail does with respect to the acute-angle of the crossing.

If he is standing close beside me I know that our separate axes of vision will meet at an acute angle in the centre of his object, and if we are further apart, at an obtuser angle.

It was a merry time with Carrmen, Watermen, & Porters: for in this Eclipſe, many of them did nothing but drinke, domineere, and ſwagger in Alehouſes; but the often going to and fro of the Pot, made them talke of that, which they had nothing to doe withall, and many times their obtuſe apprehenſions would be medling with the warres betwixt the great Turke and Preſter Iohn, how it was likely to end; […]

Be you a Remainer or a Leaver, you would have to be particularly obtuse not to see that [Theresa] May's hard Tory Brexit will cost this country and its families more than it can conceivably afford.

Another addition in Mr. [Joseph Emerson] Worcester's key to the same letter [e] is what he calls the short and obtuse sound, as in her, herd, fern, fervid. Some of these, also, for the sake of indicating the true sound, [John] Walker was obliged to spell with a different vowel. Thus her is directed to be pronounced hur, like u in tub.

[…] The Conchologist's First Book intends to do something different by describing both the shell and the soft parts of each creature together. The claim seems awfully trivial, I admit, and [Edgar Allan] Poe does press his point only by the obtuse route of stressing an expansion of terminology, from the traditional "conchology" (literally the study of shells, as retained in the title) to "malacology" (or the study of the entire organism—for the animals within the hard shells consist almost entirely of soft parts,[…]).

The general effect of even a weak infusion of coca leaves is a pleasant irritability and sleeplessness. A stronger infusion keeps hunger away, prevents loss of breath in ascending mountains, dilates the pupil, and obtuses the sensibility to the air.

[Gustav von] Bunge […] claims that its [alcohol's] primary action is that of a depressant, and that its apparent good effects are simply due to the obtusing influence upon physical and mental suffering. But this is scarcely a correct assumption, as there are individuals in whom the smallest doses produce palpitation of the heart, throbbing of the carotids, and great mental activity. He also claims that alcohol does not produce renewed vigor in tired individuals, but simply obtuses this feeling of exhaustion.

The American avidity for "action" has evidently obtused the perceptions of habitual theatre-goers to all nuances of feeling, and therefore, the harmless romancings of the elderly estranged couple, Mr. and Mrs. Arvik, are interpreted as covering unspeakable iniquities that only exist in the minds of the critics.
