What's the difference between callosity and hardness?
Callosity
Definition:
(n.) A hard or thickened spot or protuberance; a hardening and thickening of the skin or bark of a part, eps. as a result of continued pressure or friction.
Example Sentences:

(12) The results are in agreement with data on visual callosal connections in animals and confirm previous psychophysical findings (Berardi & Fiorentini, 1987) indicating the particular properties of the interhemispheric cross-talk between symmetric regions of the visual field astride the vertical meridian in man.
(13) However, even in mice with extreme deficiencies of the corpus callosum, callosal fibers originate from and terminate in all major areas of the cortex, and, within these areas, callosal cells and terminations are distributed according to the normal plan.
(14) The mean callosal area did not differ significantly between patients and control subjects, between left-handed and right-handed subjects, or between men and women.

(16) Callosal connections from the temporo-parieto-occipital junctional region course through the splenium and caudal portion of the body of the corpus callosum.
(17) Callosally projecting cells are found predominantly in layers II, III, and V and are sparse in layers IV and VI.
(18) The callosal neurons could be separated into two categories: "double callosal" neurons which project both axon collaterals to two cortical areas of the contralateral hemisphere, and "associational-callosal" neurons which send axon collaterals to both hemispheres.
(19) Results from HRP studies of callosal connections indicated that transplant efferents to the contralateral cortex are smaller in magnitude than their afferents.
(20) The nonsurgical subjects with developmental callosal agenesis and acquired pathologic processes involving the callosum revealed a varied, nonspecific reduction in cognitive function most probably related to associated extracallosal hemispheric pathology.
Hardness
Definition:
(n.) The quality or state of being hard, literally or figuratively.
(n.) The cohesion of the particles on the surface of a body, determined by its capacity to scratch another, or be itself scratched;-measured among minerals on a scale of which diamond and talc form the extremes.
(n.) The peculiar quality exhibited by water which has mineral salts dissolved in it. Such water forms an insoluble compound with soap, and is hence unfit for washing purposes.
Example Sentences:

(5) They had learned through hard experience what Frederick Douglass once taught -- that freedom is not given, it must be won, through struggle and discipline, persistence and faith.
(6) In 60 rhesus monkeys with experimental renovascular malignant arterial hypertension (25 one-kidney and 35 two-kidney model animals), we studied the so-called 'hard exudates' or white retinal deposits in detail (by ophthalmoscopy, and stereoscopic color fundus photography and fluorescein fundus angiography, on long-term follow-up).
(7) It is a moment to be grateful for what remains of Labour's hard left: an amendment to scrap the cap was at least tabled by John McDonnell and Jeremy Corbyn but stood no chance.
(8) She stopped working only when the pain made it hard for her to get to work.
(9) He was reclusive, I know that, and he was often given a hard time for it.
