elements in the two spouses respectively. Here a difference between the English law and the law as enacted by the Bombay Legislature may be pointed out. Whereas under the English law those essential conditions must continue throughout the course of the three years immediately preceding the institution of the suit for divorce, under the Act, the period is four years without specifying that it should immediately precede the commencement of proceedings for divorce. Whether the omission of the last clause has any practical result need not detain us, as it does not call for decision in the present case. Desertion is a matter of inference to be drawn from the facts and circumstances of each case. The inference may be drawn from certain facts which may not in another case be capable of leading to the same inference; that is to say, the facts have to be viewed as to the purpose which is revealed by those acts or by conduct and expression of intention, both anterior and subsequent to the actual acts of separation. If, in fact, there has been a separation, the essential question always is whether that act could be attributable to an animus deserendi. The offence of desertion commences when the fact of separation and the animus deserendi coexist. But it is not necessary that they should commence at the same time. The de facto separation may have commenced without the necessary animus or it may be that the separation and the animus deserendi coincide in point of time; for example, when the separating spouse abandons the marital home with the intention, express or implied, of bringing cohabitation permanently to a close. The law in England has prescribed a three years' period and the Bombay Act prescribed a period of four years as a continuous period during which the two elements must subsist. Hence, if a deserting spouse takes advantage of the locus poenitentiae thus provided by law and decide to come back to the deserted spouse by a bona fide offer of resuming the matrimonial home with all the implications of marital life, before the statutory period is out or even after the lapse of that period, unless proceedings for divorce have been commenced, desertion comes to an end and if the deserted spouse unreasonably refuses the offer, the latter may be in desertion and not the former. Hence it is necessary that during all the period that there has been a desertion, the deserted spouse must affirm the marriage and be ready and willing to resume married life on such conditions as may be reasonable. It is also well settled that in proceedings for divorce the plaintiff must prove the offence of desertion, like and other matrimonial offence, beyond all reasonable doubt. Hence, though corroboration is not required as an absolute rule of
