Transcription: Elektrosmose das. § 11) [Berücksichtigung der Dielektrizitätskonstante]. Bevor wir jedoch mit Helmholtz zur Vergleichung derselben mit dem Beobachtungsmaterial übergehen, bemerken wir vor Allem, dass in dieser Ableitung wie auch in fast allen späteren aufwand-gestützten Arbeiten, ein Versehen zu corrigiren ist, welches erst von Pellat bemerkt worden ist und welches, wie wir sehen werden, erhebliche Folgen nach sich gezogen hat. Hat nämlich die Flüssigkeit eine von Eins verschiedene Dielektrizitätskonstante , so nimmt bekanntlich die Poisson'sche Gleichung (6) die Form an: Allerdings könnte es zweifelhaft erscheinen ob in der Grenzschicht noch als konstant und gleich dem im Innern gültigen Wert angesehen werden darf; aber wenn man mit Helmholtz den Zähigkeitskoeffizienten $\eta$ als konstant ansieht, muss man dies wohl auch für gelten lassen. Die Rechnung bleibt sonst unverändert, nur erhält man schliesslich an Stelle von (9) die Schlussformel: Im Folgenden werden wir sämmtliche Formeln schon in dieser berichtigten Gestalt, mit Einführung des Faktors  gebrauchen. § 12). [Anwendung auf Elektrosmose]. Aus dieser Formel folgen die Erscheinungen des elektrosmotischen Flüssigkeitstransportes, wenn der hydrostatische Überdruck gleich Null gesetzt wird. ~~Da die Geschw.~~ Da in diesem Falle in dem ganzen Querschnitt verschwindet~~, folgt für die gesammte pro Zeiteinheit übergehende Flüssigkeitsmenge: wo ~~J die Gesamtstrom~~, wo die Potentialdifferenz an den Enden der Röhre, $R$ den Radius derselben bezeichnet. Somit ist die in Kapillaren von gegebener Substanz übergeführte ~~Flüssigkeitsmenge~~ einer gewissen Flüssigkeit der Gesamt-Stromintensität $J$ proportional, ohne Rücksicht auf ~~Weite~~ Weite und Länge der Röhre. Helmholtz zieht die Wiedemann'schen Messungen an Tondiaphragmen als Bestätigung dieses Satzes heran, und berechnet hieraus die Werte , doch liegen hier die Versuchsbedingungen wohl etwas anders, wie wir in § 16 noch näher ausführen werden. ¹) Siehe Perrin, Journ. chim. phys. 2, 601, 1904.

Transcription: Guerrero, the President of the International Court of Justice accompanied us from Geneva and we were to pick up Costa du Rels, President of the Council, en route as he was in France. - Holma wisely decided to travel less conspicuous- ly and was "on holiday" by himself. - The  journey was interesting and although I had been  very much alarmed at the prospect of six days ina  bus, this part at any rate was a relief  from the pressure under which I had been working.               We gor through the Franco- Swiss frontier without difficulty and reached Nimes at 11.30p.M    having made a brief stop in a way-side café to eat a picnic meal. We have had to make  a détour occasionally because of a bridge  blown up; the Rhone bridges were destroyed  right down to Valence near which we were told  the German advance guard had reached; they  were however prevented crossing the river;  it was a pity to see many fine bridges  shattered.            We left Nimes the next morning (Sunday) at 6.30 or 7 and luched in Perpignan. The vendange was in progress as we drove through literally scores of miles of vineyards. There  was practically no motor traffic, though some  vehicles were using the wood gas. In one or  two towns we did catch sight of non-Frech uniforms representing the German or Italian Commissions of Disarmament and control and an occasional vast park of abandoned army  vehicles.            Our special little bus reached the  frontier at Le Perthus about 1.30 and again  the French frontier was easy enough to pass. I had however been warning Jacklin and Guerrero that our passing would be made difficult on the  Spanish side. Guerrero being a Latin-American Spaniard was put first with his passport. In  a few minutes he explained to me that there was  difficulty; the official had turned up in his  book an order prohibiting the passage of League officials or anybody connected with the League.            The following is a bare summary of what  followed as I reported a few days later to the  Supervisory Committee:        26/9         The League party consisted of Lester, Jacklin,  Bisler, da Silva (Portuguese) and one English and one French stenographer. They were accompanied by Guerrero,  President of Court and were to pick up Costa du Rels,  President of Council, in France but latter was delayed  at Cannes and had to travel separately.          Guerrero  had diplomatic visa from Spanish Minister who  aad  refused diplomatic visa to Lester,  although latter carried diplomatic passport. Spanish  Consul in Geneva gave visas for all the party. Portu- guese Minister gave diplomatic visas for all.           On arrival at Le Perthus, Guerrero and Lester  first entered Spanish frontier office where officer-in- charge said he had some instruction about League people.  In his book he turned up an instruction which he said was dated 13th of August and forbade the entry of any  League official ar any one connected with the League.  On this ground he refused to allow the League officials to pass but though there would be no difficulty about Guerrero. This was Sunday, 3 p.m. Following protest, frontier official agreed refer matter to Govrnor. Gover- nor's Secretary though there would be no difficulty  about Guerrero, but Governor could not be found; it was not until Monday that Governor's confirmation arrived.  Guerrero then spoke personally [to him on telephone] pro- testing against decision and urging reference to Madrid. Governor undertook to do so and promised reply before  7 p.m. Monday evening. No reply came till Tuesday at  11 a.m. In the meantime, Lester persuaded Guerrero - who

He refused Jackin's suggest- ion that he might tell me something about it and threatend to bring the matter to the Su- pervisory Commision. - I had then remarked to Jacklin that I would be greatly relieved if I were treated by him as something so important  as a Member of Section and that while I had hoped not to have to make any report on Avenol to the Supervisory Committee, if he raied the matter, I would indulge myself for half-an-hour. - The other letter to Kisch was written by hand.  I think the reason must have been that he dared not to ket his private Secretaru see it. In it he said he wished only to express his heartfelt and profound admiration for the gallant fight the British were putting up ; they were fighting not only for themselves, but for all of us in the  world! I have often been nauseated by Avenol in recent months, but thi swas the limit ; it reflected I suppose the r eaction on him of the  continued British defence, but he also disclosed to Jacklin another reason by word of mouth: he told him he hoped to be made the go between the French and British Governments. When Jacklin told me this, I laughed saying that neither one or the other would touch him: Avenol was nobody in France and a lot less than that in London. He certainly is an  incredible creature.  Sent knowledge to Salem 26/9 Lester to Hambro Following is for your use at Supervisory Commission Stop I had intended discussing with the Commission the situa- tion of the Secretariat in Switzerland, the possibilities of work and survival here, the question of temporary transfer of all or part elsewhere. I have been rendered uneasy by the signs  of change of attitude of the Swiss Government in the last two months Stop There have been certain facts and fairly clear tendency which have led me to conflusion that the Swiss Govern- ment would not be displeased at Secretariat departure or liquidation Stop Appreciate Switzerland's difficulties due  to geographical position and recent events Stop Increasing volume of obstacles however render continued efficiency of technical services very doubtful and cannot shirk raisng  problem of transfer Stop Communications by letter are often  slow and uncertain and telegraphic communication with Geneva  is deteriorating Stop I have personally for more than sic months favoured - and still favour - transfer from Switzerland of vital techni- cal elements, but policy puresued till first September prevented serious consideration and preparation and seemed  envisage practical liquidaction this year.  The consequences of the closing of the Spanish frontier by secret order the day the Labour Office party passed through now reveals a new and worse situation.  I realize there are arguments for the maintaining  official headquarters at Geneva, or somewhere in Europe,  to keep the basis for unltimate reconstruction of inter-

Description: Handwritten and typed diary entries relating to Lester's time as Acting Secretary General of the League of Nations in Geneva. One of the most notable entries in this diary is Lester's extensive account of his meeting with James Joyce and his family in Geneva in December 1940. The Joyce family had fled their home in Paris the previous May and sought Lester's help in obtaining a visa for their daughter Lucia; the Nazis had refused to issue her with a visa and she remained in a mental health clinic in German-occupied France. A related letter from Joyce to Lester prior to this meeting is also included in the diaries, as are letters from Giorgio Joyce, son of James and Nora Barnacle [Joyce], and Carola Giedion-Welcker, a German-Swiss art historian and close friend of the Joyce family, following the death of James Joyce in Zurich less than a month later. Diary also includes letters and telegrams from: Alec [Alexander] Loveday, Director of the Economic, Financial, and Transit Department of the League; Sir Walford Selby, British diplomat; Arthur Sweetser, League of Nations Public Information Section; John Gilbert Winant, Director- General of International Labour Organisation; [Humphrey] Hume Wrong, Canadian Advisory Officer to the League of Nations; Elizabeth Wiskemann, British historian; Royall Tyler, Economic and Financial Section of the League of Nations; Carl Hambro, Head of the Supervisory Commission of the League, and René Massigli, French diplomat. Also includes letters and telegrams to: Ned [Edward Joseph] Phelan, International Labour Organisation; Carl Hambro, Head of the Supervisory Commission of the League; Elsie Lester; copy letter from Seán Murphy, Irish Minister Plenipotentiary in France to James Joyce, author; Nora Barnacle, wife of James Joyce, and Frank P Walters, Deputy Secretary General of the League of Nations. Some of the diary entries and correspondence 15 feature codenames with later annotations by Lester giving the individuals' real names. Diary also includes two black and white photographs: one of the overturned bus that Alec [Alexander] Loveday and others had been travelling in when it crashed near Grenoble, France, in August 1940, and the other is of a Connemara pony taken by Ann Lester [Gorski].
