Murphy will be glad to provide you with the occasional capacitor which
has considerably more leakage than another. In a parallel circuit,
this may be of no importance, but in a series circuit it may be fatal.
Likewise, since this box is going to be outdoors, Murphy may cause dew
to condense more on one cap than the other, again of little or no
consequence in a parallel arrangement.

These things can be overcome, but the designer must take them into
account before construction begins. Just slapping a couple of caps in
series with no further thought is asking for trouble.
