Catalog type History
Provenance Used to get specific gravity or viscosity of urine (density=specific gravity x volume). Used in the laboratory of Dr. Claude S. Hudson (1881-1952), Chief, Division of Chemistry, National Institute of Health (NIDDK). Hudson was a renowned specialist on carbohydrate chemistry, formulating the "lactone rule" about carbohydrate molecules’ shapes, among other achievements, and mentoring many other award-winning scientists. Per conversation with Dr. Kenner Rice, 3/2001: Hudson had a student from Georgetown and as was his custom, he took the student out on the town the night before the student’s boards. The next morning the student, with hangover, was asked about Hudson’s rules. The student said that Hudson’s first rule is that "any drink with gin is a good drink." Whereupon Hudson stood up and shouted "That’s my boy!"
Notes Restrictions: mercury
