The indexed term 'acuaesthesia' (relating to sensation at particular points) is defined in the letter WHRivers/2/3/3 within this collection.

Myers praises Rivers for his work, but goes on to try to convince Rivers that hypnosis can be used effectively to reveal repressed memories (something Rivers is against).

This is framed as a rebuttal of Professor Alexander Forbes. Forbes wrote a letter which appeared in 'Nature' for 14th December 1929 refuting the arguments MacCurdy made in criticism of the mechanistic interpretation of reflex functions. MacCurdy here therefore justifies his own position and gives further detail to support his view about 'vicarious functions' and the central nervous system. This hinges on the definition of the term 'automatic'.

This collection of notes includes a description of an experiment, a diagram as well as a photograph of some apparatus and a graph representing data. A scrap of data print-out included in this collection has the name 'H. Head' (Henry Head) written on the back with the date, October 1907. This suggests a connection with the experiment carried out by W. H. R. Rivers on Head's arm.

Head's thumb has been drawn on in ink, but there are also pen markings added onto the photograph labelling different parts of the thumb in red ink with lettering.

A grid has been drawn on Head's hand in ink, with dots arranged within the grid to show the arrangement of nerve endings beneath the skin.

Head's arm has been drawn on with ink markings to show the location of nerves beneath the skin, and the words 'Line of change' written twice following the wavy lines that show the area under investigation.

A grid has been drawn in ink on Head's hand to show the location of nerve endings beneath the skin, with dots arranged within the grid to show their position.

The ink markings on the skin show the location of nerve endings throughout the area.

A grid pattern has been drawn on Head's hand in ink, with dots inside the grid.

There are ink markings on Head's skin showing the area of investigation and the location of nerve endings.

Head's arm and hand have been drawn on with ink to mark location of nerve endings beneath the skin.

There are various ink markings drawn on Head's arm and hand to show the location of nerves beneath the skin, and a grid with dots inside.

There are ink markings on the photograph in red and blue ink. Beneath the photograph, on the card mount, are written the words: 'Red= loss of light touch; Blue= line of change to Prick'.

Head's thumb has been drawn on in ink, but there are also pen markings added onto the photograph labelling different parts of the thumb in red ink with lettering.

There are ink markings on the photograph in red and blue ink. Beneath the photograph, on the card mount, are written the words: 'Red= loss of light touch; Blue= line of change to Prick'.

A grid patterm has been drawn on Head's hand in ink with dots arranged withink it to show the location of nerves beneath the skin.

There are ink markings drawn on the skin of Head's arm and thumb to indicate the location of nerve endings.

Head's arm and hand have been drawn on with ink to show location of nerve endings beneath the skin.

There are ink markings on the photograph. Beneath the photograph, on the card mount, are written the words: 'Red= loss of light touch; Blue= line of change to Prick'. However, there are no red markings on the actual photograph, only blue.

Head's arm has been drawn on with ink to show the location of the different nerves beneath the skin.

Head's arm has been drawn on with ink to show the location of the different nerves beneath the skin, and the words 'line of' can also be made out (the third word, which would be 'change', is out of sight).

A grid has been drawn on Head's hand in ink, with dots arranged within it to show the location of nerve endings beneath the skin.
