The celebrated Foulises, of Glasgow, attempted to publish a work which should be a perfect specimen of typographical accuracy. Every precaution was taken to secure the desired result. Six experienced proof-readers were employed, who devoted hours to the reading of each page; and after it was thought to be perfect, it was posted up in the hall of the university, with notification that a reward of fifty pounds would be paid to any person who could discover an error. Each page was suffered to remain two weeks in the place where it had been posted, before the work was printed, and the printers thought that they had attained the object for which they had been striving. When the work was issued, it was discovered that several errors had been committed, one of which was in the first line of the first page.
