There were picturesque moments when, after centrifuging, the organisms lay in coiling cloudy masses at the bottoms of the tubes; or when the red corpuscles were completely dissolved and the opaque brick-red liquid turned to the color of pale wine. But most of the processes were incomparably tedious: removing samples of the culture every six hours, making salt suspensions of corpuscles in small tubes, recording the results.

He never knew they were tedious.

Tubbs came in now and then, found him busy, patted his shoulder, said something which sounded like French and might even have been French, and gave vague encouragement; while Gottlieb imperturbably told him to go ahead, and now and then stirred him by showing his own note-books (they were full of figures and abbreviations, stupid-seeming as invoices of calico) or by speaking of his own work, in a vocabulary as heathenish as Tibetan magic:
