Zchoo vac under tho iaprocsioa that, '.-hat he raid in hie presentation to tho Ivies Lead Coccittee at Barna in July 1030, ri^ht tot have loon interpreted in euactly the se:a:o it van count. l.'o, therefore, arranged for a nootinr botvreon Sr. hieho c , rroit iloeppcr (proainoat medical aoaber of the Coccittos} and Sr. ("ho vac also present at the first discus si er and vho -pave us tho ini ores ion contained in our .1otter to you of August ii. 1C 30) . This meat in" tools place on October 31, 1960, in tho pres onso of our Products Advisor, S r . A. llosaaer. In essence, this is '..'hat Dr. ZoLco sails 'x ho teste eorrplc tod by July 1330 (vh.,...i .u ......-so ...eeo hi si first presentable n on DHL to the Lend h i11 eo ) arid tho limited tine ..,v.":,il.able for those to t s ..id soot silos' to obtain scientific proof regarding the cii.sts of 'fll'A. Giaso tests are und'srva.y at tho present tiro i : viil, however, be possible to furnish sons proofs in tho foreseeable future. On the- other hand, those tecta which -rare completed-by July 1930 did substantiate certain, tssuspiioco and this .nude it possible for Dr. Kohoo to assume the responsibility cf rococcoadiaj the use of THL in the U.G. 00KF 03049 fT. VO VC Dr. hohoo stressed the fact that tho introduction of- DHL in. the US vas nado possible'only by his positive ottitud.0 Ko maintained that since it is permitted te uso '13L there i3 a o ro z on to put a. baa on TliL. . . ' . In reply l:o ... if is question by .Prof. Hoojrgor ro.g&rdiaj t b a d 3 r - .1 In; 1city of-Tin, versus i'DL, Dr. Kobo said z. . -.. : o rove that the uso of TAL in inoran In controlled concentrations has >had -t o adverse --effects -dtid can he considered as not ^dangerous. b This i s toacked iup-Vby controls extending over .a period of more ithan thirtyyears. n TML is loss readily absorbed by the human skin than TEL, In this respect TML is less dangerous. On"the other hand, as a result of its higher volatility, eoto lead, goto into the atmosphere during' evaporation of nogas containing TML than rould be the case with TSL. This increases T M L 5a , relative toxicity. **) Expressed in ausbers B r . Kehoo believes that T M L fc tonicity is about two to two and a half times that of TEL. However, since experience proved that the use of TEL does not involve any hazards to public health, this - according to Br. liehoc - also applies to the use of TML, Dr. ICehoo emphasized that this is his personal opinion and that ho trill be able to produce evidence of the harmless nature of TEL only at a later data, i ,,e0 when tho tests which are underway now will have yielded sufficient data. Ho has, however, no doubt that these results will be positive **) 'with regard to this paragraph it should be mentioned, that Prof. Eccggcr, Dr. Buf and Dr. Moasmex wore under the impression 'hat Dr. ICehoo *3 statement was a summary and referred to o? r- .. ... day , Basing on literature received tho other day on TEL, kovovor, vo rather suspect that Dr. lichee only had the e~or tio:a .L inha1a.ticr. haz ard in mind.. Possibly, there is just another mi sunder standing here. Dr. Bui to whom we talked after the meeting said that Br. Eehoo, this time, sounded somewhat more positive and that some, of his statements varied from those made in July. Dr. Hohoc, in turn, felt that his statements vers identical and cay have been partly misinterpreted. Doth, Dr. Bui and Prof. Hoogger welcomed the opportunity of thoroughly discussing the whole problem and tho latter promised to pass on this latest information to the Lead Committee accordingly. Obviously, from a supply and quality point of view fast action to secure- official clearance to use TML in Switzerland would be highly desirablo . Me understand from our Supply Manager, Mr. 17. liUller, that this question was also discussed <it the recent Vienna Supply Mooting and you may rest assured that wo fully appreciate tho problems arising from a ban of TML in this country. ` fho e avunion now is what action we can take to obtain official iaarance with as little delay as p-ossible. KF 0003 V. . ^ - *> -3 a) From a technical point of yj axt ve have a'clear situation, .We know the advantages offered by TliL and va al3 0 know that there are no negative aspects regarding engine life b) The nodical aspect, however, is a different story, lou rill agree that Dr. Kohoo's presentation to the Lead Committee and his latest statements during his second visit are not too convincing,, marticularly when you keep in iaind that you face a group of rather conservative and cautious non vho took a good many years to prepare a finai report on 2?3L.
