Ada's letters breathed, writhed, lived; Van's Letters from Terra, 'a philosophical novel,' showed no sign of life whatsoever...

Poor Van! In his struggle to keep the writer of the letters from Terra strictly separate from the image of Ada, he gilt and carmined Theresa until she became a paragon of banality. This Theresa maddened with her messages a scientist on our easily maddened planet; his anagram-looking name, Sig Leymanksi, had been partly derived by Van from that of Aqua's last doctor.

...After beaming to Sig a dozen communications from her planet, Theresa flies over to him, and he, in his laboratory, has to place her on a slide under a powerful microscope in order to make out the tiny, though otherwise perfect, shape of his minikin sweetheart, a graceful microorganism extending transparent appendages toward his huge humid eye. Alas, the testibulus (test tube - never to be confused with testiculus, orchid), with Theresa swimming inside like a micromermaid, is 'accidentally' thrown away by Professor Leyman's (he had trimmed his name by that time) assistant, Flora, initially an ivory-pale, dark-haired funest beauty, whom the author transformed just in time into a third bromidic dummy with a dun bun.
