Lastly, it was said that the request for a draft contract for a solicitor's approval should be regarded as an indication that the respondent was not accepting the terms of purchase set out in the grant of the option, but that he required a statement of the appellant's terms in the form of a draft contract so that his solicitor might consider them in order to decide whether or not the respondent would agree to purchase upon them. I am unable to accept this submission. The taking up of the option is not said to be subject to a contract approved by the solicitor, nor, in my opinion, can the last paragraph of the letter be read as making that taking up subject to such a contract. Rather, in my opinion, that paragraph of the letter ought to be read as no more than an indication that the respondent desired the agreement to purchase to be reduced into a formal document, in which event he desired his solicitor to ensure that that document did express the agreement which had been made. The reduction of an informally made agreement into a formal document is not infrequently done as a prudent matter of business. Even if it had been thought by the respondent that some additional terms of a conveyancing nature might be agreed upon and expressed in the formal contract, that circumstance, in my opinion, would not make the exercise of the option ineffective, and nothing is to be derived from the oral evidence which, in my opinion, was irrelevant to the meaning or operation of the documents in this case.
