J. This being an amlvorscry year a apodal program was prosaritod, consisting of reviews of the aecoapliahmonts and progross In tho battery field during the past 10 years. In addition to prosontation of tho results of tho past yoar?s battery rosoarch and dovolcpudat activities, A list of tho pepors prosontod. their aathors and affiliations is'attached, with sooo additional notos on tbo lead-add battery paper preeented ty Dr. Willihngan*. In tho post. abstracts of all tho papers wore Bade available to aeobers of the Lead Industries Association. Complete papers wore unobtainable bocouso of security complications. This year, bowovor, tho Signal Corps intends to jwbliah the full proceedings of tho Conferonco, since all popors hare boon doclossifiod. Inasmuch as copies in quantity are cvr.ilable at a loner cost. $5.00 oach as compared with $10.00 for singlo copies, it is suggested that nodbore Interostod in obtaining a copy of tho procoodings of this Conference write to the Load Industries Association to this offoct* Copies ere expoctod to bo available within too months. m* %` 2? -.
