TRANSACTIONS OF SECTION I. 7ol 
ing and technique, that I analysed my own memories, and I tried to make clear 
to myself the question of the memories of childhood, a little fogged by the re- 
searches made on them. 
The result of my researches seems to be that the localisation of remote or 
mediate memories—in other words, the processes of localisation, whilst taking 
account of conservation, reproduction, and recollection, elements of the memory— 
and also of the association of ideas, are carried out to a certain extent in 4 way 
slightly different from the processes of immediate localisation. 
Direct localisation—that is to say, the proceeding which consists in fixing the 
place of a word in a series, the place of an event or of a fact, the place being 
assigned according to the knowledge of the memory itself, and without other 
motive than memory—plays a more important part and, at all events, a more 
certain one than in immediate localisations. There appears to be a close and 
intimate relation between memorising, between the fixing of memory and the 
reproduction at a remote epoch ; the intensity of that image has made it appear 
spontaneously without the memory intervening or the association of ideas 
classifying it. 
Localisation by association is apparently the most utilised by the subjects, but 
its results contradict one another: they form the basis of great discussions, and 
guide minds at least towards analogous trains of thought, especially on account of 
the elements connected together by circumstances and of neighbouring situations, 
so to speak. The landmarks are not clearly defined, but they are very numerous. 
Mediate localisation without association plays an important part; the subject 
uses definite fixed landmarks, which fall into order in his mind without having 
recourse to association. 
The localisation by the association of a feeling is to be noticed in the most 
remote memories, when the landmarks are not distinct and when the feel- 
ing of the intensity of the image is dulled, and, at most, like a subservient 
phenomenon, but always indefinite, utilised, however, as a directing idea. 
To this mode of localisation can be opposed localisation by recollection ; reason 
then comes in, and a long deliberation occurs which takes up all the attention of 
the subject. These are in our case @ posteriori distinctions ; there may be mistakes, 
and inquiries into the first recollections of childhood may form an exception. 
Localisation by reason is the only conscious form; it must be imposed on the 
attention of the subjects as a means of investigation, because, as I have already 
said, the processes of localisation are based on reason. The subject looks for his 
landmarks, he knows how to manipulate his images, and, above all, he tries to 
take advantage of this recollection and of the examination of his mind, 
In one word, briefly to recapitulate my researches, remote and mediate 
memories are localised in time and space according to the same processes as imme- 
diate localisation, but with a slightly different mechanism, Memory and association 
of ideas play a secondary part, and the discovery of good landmarks is dictated 
principally by reason. Thus we have the existence of a spontaneous automatic 
cerebral localisation resulting from latent qualities and subservient to thought, 
which localisation acts and exists independently of images. The mechanism is 
certainly extremely complex, and I propose to discuss this subject in a work 
on memory.

Discussion on Conduction and Structure in the Nerve-are and 
Nerve Cell. 
Professor J. N. Langley, in opening this discussion, said that he restricted 
himself to a consideration of the general scheme of structure and arrangement of 
the nervous system in vertebrates, and the broad relation of this scheme to nervous
