Copy letter from an unknown correspondent, to Messrs Harrison & Sons, Pall Mall 'The oil sheets you sent us on Jan 13 are very bad indeed, often being used once or twice the water goes through them, & the letter-book is being quite spoiled. For type-written letters which have to be well wetted it is quite useless. Pray send us at once some proper sheets (two dozen). I enclose one of your sheets that you may see what sort not to send'. 17 March 1896
