Louisville, Kentucky 40232, U.S.A. 1.5th June, I988 Dear Lance, I was asked sometime ago :o comment on the ~ paper submitted by Professor Cain to B.&W. relating to the Capri study he undertook for you earlier this year. For your information, a copy of my original views are enclosed. As a result o£ th~ Alan Heard asked me to elaborate further on one of the points (No. 2) of this note. Easeatially, my comments arose from looking at Table VII from Cain's drat~ paper (which is also appended). By examining the ~ in product ~pea in temm of both the weights burnt and analytes measunut, a pattern should emerge .m. terms that the. ,% weight saving of Capri relative to the other products should be reflected in the % reducuons ox u~ analytes monitored for (.this is exptes.u~ in the table be.low). ,% REDUCTIONS BETWEEN PRODUCT TYPES Parameter CO Hydrocarbons NO, Partk:ies (1) Paxticles ('2) DoralLdghts-Cal?, ~ ,% DoralLights 34 23 39 0 11 *-3 Marlboro-Capri % Marlboro 36 26 41 14 19 14 VirginiaSlims - Capri % VirginiaSlims 34 20 24 8 13 16 * NOTE: -re indicates Capt'/is higher than Dotal Lightst 0 ",,d ClibPDF - www.fastio.com

(This fact is mpported by our own sidesucam ~ studies). I Iowever. on balance within the paper, I feel that to try and put the whole subject into context, it would be advisable for someone to comment on the vxiability oftbe data that ca, be derived from Table VII, point out that Capri produces the Iowest absolute EI'S levels anti discuss the e'r$ p~.-,~,a~c GSP) ~ of Cagi a.d the oe~ pred.c:s.
