“17. From a plain reading of the Section it is manifest that to make an entry relevant thereunder it must be shown that it has been made in a book, that book is a book of account and that book of account has been regularly kept in the course of business. From the above Section it is also manifest that even if the above requirements are fulfilled and the entry becomes admissible as relevant evidence, still, the statement made therein shall not alone be sufficient evidence, still, the statement made therein shall not along be sufficient evidence to charge any person with liability. It is thus seen that while the first part of the section speaks of the relevancy of the entry as evidence, the second park speaks, in a negative way, of its evidentiary value for charging a person with a liability. It will, therefore, be necessary for us to first ascertain whether the entries in the documents, with which we are concerned, fulfil the requirements of the above section so as to be admissible in evidence and if this question is answered in the affirmative then only its probative value need be assessed.”
