Sub-series A-1 contains experiment notebooks from the Chemistry Laboratory, Cambridge, concerning the study of stereochemistry. Of special relevance are the experiments pertaining to the optical activity caused by the restriction of the rotation of a trivalent nitrogen atom. It includes material produced at the Sir William Dunn Institute of Biochemistry related to oxidation reduction systems with particular relevance to the reduction of glutathione and the study of peroxidases in milk and horseradishes. This sub-series is comprised of 4 files (files no. 1 to 4), which are arranged chronologically.

Sub-series D-2 contains correspondence of Dr. Elliott relating to various topics. Of special importance is the correspondence with Baxter Laboratories concerning “Elliott’s B solution”. This sub-series includes a portion of Dr. Elliott’s lecture notes for courses taught on Biochemistry. This sub-series also includes some files relating to Dr. Elliott’s “Unorthodox Career”. This sub-series is comprised of 22 files (nos. 134 to 145).

Sub-series D-1 contains correspondence of Dr. Elliott concerning topics of various natures. This sub-series includes research notes, newspaper clippings, manuscripts, and typescripts of speeches. This sub-series is comprised of 48 files (nos. 76 to 133), which are arranged alphabetically.

Sub-series A-3 contains experiment notebooks from the Montreal Neurological Institute, concerning experiments on brain swelling as a result of head injury and neurosurgery. Brain slices were examined to determine the effect of aerobic and anaerobic metabolism of electrolytes, pH, oxygen tension, narcotics and convulsants. Of special relevance is the experiment measuring the acetylcholine (Ach) content of cat and rat brains. This sub-series is comprised of 14 files (files nos. 34 to 47), which are arranged chronologically.

Sub-series A-2 contains experiment notebooks from the Graduate School of Medicine, University of Pennsylvania, concerning the measurement of peroxidase activity of animal tissues, the activity of the “succinoxidase system” and the effects of redox indicator dyes on metabolism. Includes experiments related to the aerobic and anaerobic metabolism of glucose, lactate, pyruvate and succinate by slices of tumor tissues using manometric, analytical and isolation procedures. This sub-series comprises 29 files (files nos. 5 to 33), which are arranged chronologically.
