 voice, the volumes are hunted out and arranged 

 side by side in the order in which their titles are 

 read, while the entry on the invoice is checked in 

 the margin with a pencil. These pencil-checks 

 are afterwards copied into the margins of the 

 book in which our lists of foreign orders are regis-

 particular work has been received or not. This 

 order-book, with its marginal checks, is the only
