An iatrochemist performs a uroscopy, examining a small glass flask, while other activities take place in his busy workshop. A woman is waiting for her diagnosis, having brought the flask of urine in the wicker basket seen hanging from her right arm. Celestial and terrestrial globes, a hanging reptile, a seated dog, and alchemical apparatus are seen throughout the workshop. In the background are four assistants working near the hearth. In the right foreground a young man is working the bellows.
