Let's examine each statement:
Statement I: Uremia (a condition involving abnormally high levels of waste products in the blood) and uric acid diathesis (a predisposition to uric acid-related conditions like gout) would typically be found under more specific organ or system chapters in the BBCR (Boericke's Repertory). Uremia would likely be under "Urinary Organs" or "Generalities" related to blood conditions. Uric acid diathesis might be under "Generalities" related to diathesis or under specific joint complaints if gout is a prominent feature. They are not typically grouped under "Sensations and Complaints in General" as primary rubrics. Thus, Statement I is incorrect.
Statement II: Glycosuria (glucose in the urine) would be found under the "Urinary Organs" or "Urine" section of Boenninghausen's Therapeutic Pocket Book (TPB), likely within a chapter dealing with urine characteristics. Milky urine (chyluria or phosphaturia) would also be located in the same general section. While "Micturition" is a related aspect, the TPB is structured based on modalities and concomitants associated with symptoms, and these specific urine characteristics would be listed under the urine itself, not solely under the act of micturition. Therefore, Statement II is also likely incorrect as the primary location.
Given this analysis, both statements appear to be incorrect regarding the typical organization of these rubrics in the mentioned repertories.
