The board of directors or the president and secretary of any insurance company may call special meetings of the stockholders of the company whenever they may deem it expedient so to do, first giving thirty (30) days’ notice of the time, place, and purpose of the meeting in a newspaper published in the county where the company is established, or, if there is no newspaper published in the county, then in a newspaper published in an adjoining county. At all of these special meetings, not less than two-thirds (?) of the shares shall be represented either in person or by proxy in order to constitute a quorum for doing business. The stockholders of the company, when so assembled, may act on the business for which they were specially called together, and also on any other business as may be transacted by law at any regular meeting of the company.
