The author studied the trend of mortality by cause of death in the age-group 45-64
for three causes, and also for all causes combined. The trend was analysed according
to the ‘départements’ of France, on the hypothesis that the distribution of rates
of mortality by department at the time t was log-normal. To allow for the time
sequence of observations, i.e. when t varies, a normal distribution in two variables
was fitted. The method failed for other age-groups and the results for the mortality
by cause were unacceptable. The author proceeded to study an alternative method
based on Markov chains and ingeniously refined the results of the first method,
producing projected rates of mortality by cause and for all causes. In the second
section of the paper, the author investigates underlying cyclical variations in
mortality by harmonic analysis.
Pages 215-88 are devoted to a report on a Seminar held in February, March and April
1968 at the Statistical Institute of the University of Paris under the general title Actuarial
Calculations, Technique and Financing of institutions or plans for retirement benefits.

in an integrated data processing organization.
PETITJEAN,M. La réversibilité des pensions dans les régimes de retraite du secteur public
et para-public (Reversionary pensions in State and Para-State retirement schemes),
pp. 17-22. Criticizes the lack of rights for the widower of a deceased State female
employee as being contrary to the concept of equal rewards; the level of widow’s
pension which is normally 50% of the husband’s; and some aspects of the cost.
vie à la prime de risque (Danger of risk premium
life reassurance), pp. 23–8. The author feels that reassurance of the mortality risk
for an endowment assurance should be regarded as reassurance of the term assurance portion; the pure endowment portion being retained by the ceding office.
This means that the reassurer receives a risk premium for the whole of the nominal
sum reassured, and not for a decreasing amount at risk.
