MUTUAL LIFE ASSURANCE. 



THE SCOTTISH PROVIDENT 

 INSTITUTION combines the advantaga 

 of Participation in the whole Profits with mo- 

 derate Premiums. 



The premiums are as low as those of the non- 

 participating scale of the proprietary compa- 

 nies. They admit of being so not only with 

 saffety. but with ample reversion of profits to 

 the policy-holders, being free from the burden 

 of payment of dividend to shareholders. 



At the first division of surplus in the present 

 year, bonus additions were mode to policies 

 which had come within the participating class, 

 varying from 20 to 54 per cent, on their amount. 



In all points of practice — as in the provision 

 for the indefeasibility of policies, facility of li- 

 cence for travelling or residence abroad and of 

 obtaining advances on the value of the policies 

 — the reaulations of the Society, as well as the 

 administration, are as liberal as is consistent 

 with right principle. 



Policies are now issued free of stamp duty. 



Copies of the last annual report, containing 

 full explanations of the principles, may be haa 

 on application to the Head Office in F.din- 

 bnrgh ; of the Society's Provincial Agents ; or 

 of the Resident Secretary, London Branch.

 non-appearance, or any extra charge what- 

 ever.
