“ It is in itself a reasonable rule, enabling the guarantor to know the nature and extent of his liability; to exercise due vigilance in guarding himself against losses which might otherwise be unknown to him; and to avail himself of the appropriate means in law and equity, to compel the other parties to discharge him from future responsibility. The reason applies with still greater force to cases of a general letter of guaranty; for it might otherwise be impracticable for the guarantor to know to whom, and under what circumstances the guaranty attached ”
