Michael shuddered. One of the consequences of the doctor's continued failure to invigorate the Quinta Essentia of the Humors in test subjects was Kurt Stoltz being authorized to work on artificial cryolite so he could make pure aluminum. Dr. Gribbleflotz had theorized that the impurity of the materials might be why his experiments weren't producing the results he expected. Well, Kurt was welcome to the task. Even the stink of ammonia that hung around the Spirits of Hartshorn facility was preferable to being around hydrofluoric acid.

"I have been unable to observe anything happening when I use my pyramid to invigorate the Quinta Essentia of the Humors in test subjects. I believe the reason I can't see anything is because the actions taking place are not detectable by the human eye. However, a special photographic technique I have read about should allow me to observe the otherwise invisible forces at work and help me progress my research. The diagram you are looking at is taken from a reputable up-time source, and both Frau Sebastian and Frau Frost believe that such a device should produce the Kirlian images I desire."

Michael dragged his attention back to what Dr. Gribbleflotz was saying. At least this wasn't going to be anything as dangerous as hydrofluoric acid. The diagram was a simple electronic circuit, easily understood by anyone with knowledge of the up-timer science. Of course, actually making the device needed a level of expertise he knew the doctor lacked. For that matter, so did he. What was needed was a specialist, someone who knew how to make a transformer. Fortunately, such people were relatively easy to find in Grantville. "Where are you intending to use this…" Michael paused to think up a suitable name the doctor would enjoy. "Kirlian Imager, Doctor?"
