Miguel Antonio Rodriguez y Lopez (microbiologist; small, tawny, with intensely black hair, which he wore rather long, and with a reputation, which he did nothing to discourage, of being a Latin in the grand style as far as the ladies were concerned) cultured the dust from Vemadsky's gas-analyzer trap with a combination of precision and respectful delicacy.
"Nothing," he said eventually. "What foolish growths I get look harmless."
It was suggested that Junior's bacteria need not necessarily look harmful; that toxins and metabolic processes could not be analyzed by eye, even by microscopic eye.
This was met with hot contempt, as almost an invasion of professional function. He said, with an eyebrow lifted, "One gets a feeling for these things. When one has seen as much of the microcosm as I have, one can sense danger-or lack of danger."
This was an outright lie, and Rodriguez proved it by carefully transferring samples of the various germ colonies into buffered, isotonic media and injecting hamsters with the concentrated result. They did not seem to mind.
Raw atmosphere was trapped in large jars and several specimens of minor animal life from Earth and other planets were allowed to disport themselves within. None of them seemed to mind either.
