SIR,—Mr. J. Hunt should not assume so easily that do

not knoW my homework. 1 had in fact noticed what he describes as a 'glaring error' in Mr. Kerbys article, and indeed some other mistakes which Mr. Hunt has not pointed out. But I am sure that neither you, sir, nor your readers would welcome long letters itemising all the minor inaccuracies which are written from time to time on the subject of purchase tax. NO reader is likely to come to much harm when a contri' butor quotes incorrectly the rate of tax which a registered trader has to charge on a chemistry set-- least of all the registered trader himself, for he w have in his possession the official list of rates. But a member of the general public who thinks he can save purchase tax by converting his van to an estate car without informing the Customs and Excise may find himself liable to prosecution if he acts on this belief. Whether or not Mr. Kerby needed to be told this is beside the point. My concern was solely to ensure that his article did not mislead any of your readers on this issue. I deliberately refrained from the pedantry which Mr. Hunt seeks to thrust upon me Yours faithfully,

ill
