Now, here’s a branch of the sciences that has been too long neglected. From the OED:
Od. A hypothetical force held by Baron von Reichenbach (1788-1869) to pervade all nature, manifesting itself in certain persons of sensitive temperament (streaming from their finger-tips), and exhibited especially by magnets, crystals, heat, light, and chemical action; it has been held to explain the phenomena of mesmerism and animal magnetism.
An odd name, you say? But it was chosen for impeccably logical reasons: “I will take the liberty to propose the short word Od for the force which we are engaged in examining. Every one will admit it to be desirable that a unisyllabic word beginning with a vowel should be selected… for the sake of convenient conjunction in the manifold compound words…. Instead of saying, ‘the Od derived from crystallization’, we may name this product crystallod.” (Ashburner 1850, tr. Reichenbach’s Dynamics 224). Those interested can pursue their odylic studies here. Od’s most significant appearance in literature is probably in the Seventh Book of Elizabeth Barrett Browning’s Aurora Leigh:
We think, here, you have written a good book,
And you, a woman! It was in you—yes,
I felt ’twas in you: yet I doubted half
If that od-force of German Reichenbach
Which still from female finger-tips burns blue,
Could strike out, as our masculine white heats,
To quicken a man. Forgive me. All my heart
Is quick with yours, since, just a fortnight since,
I read your book and loved it.
But it is also referred to in Avram Davidson‘s The Enquiries of Doctor Eszterhazy, a collection of stories about curious events in the Empire of Scythia-Pannonia-Transbalkania which I recommend to anyone interested in fine prose and recondite phenomena.
