Thus, the effect of including these slighter shocks is to increase the amplitude of 
both periods, and to place the maximum epoch of the semi-annual period a month 
earlier. 
47. Zante .— Schmidt and Fuchs. 
Duration of record, 1859-1878. Number of earthquakes, 246. 
The list on which this discussion is founded is compiled from those given by 
Schmidt and Fuchs for the south-east of Europe. The former extending from 1859 
to 1878, the latter from 1865 to 1884, though not recording any shocks later than- 
1874. For the years 1859 to 1863, Schmidt’s records, with only seven exceptions, 
are all taken from Baubiani’s catalogue. For the remainder of the time, Schmidt 
and Fuchs do not seem to have made use of the same authorities, for their dates 
agree in only a comparatively small number of cases.

Now, the average number of earthquakes felt in Zante every year is 34‘8 or 43‘8 
according to Barbiaisii, and 8’2 according to the list compiled from Schmidt’s and 
Fuchs’ catalogues. M. Barbiani’s catalogue may perhaps relate to a more than 
usually disturbed interval, but it was compiled by a resident in the island, and 
therefore probably includes a much greater number of slight shocks than the other 
list. This may account for the difference in the maximum epoch of the annual period
