The Eyes Have It

Kidney stone photographs from the Louis C. Herring & Co. Kidney Stone Analysis Laboratory (“We Leave No Stone Unturned”). Painfully and surprisingly beautiful. There’s also poetry in their reports and analyses as well as in they way they describe the initial visual inspection of the stones:

“The true nidus is invisible because it is the first crystal or aggregate of crystals precipitated from solution and deposited at what eventually becomes the stone site. An “apparent nidus” is either a region from which crystalline forms radiate or the geometric center surrounded by concentric laminations.”
