Remarks on "Piezonuclear neutrons from fracturing of inert solids"
  In two series of measurements, Cardone, Carpinteri et al. report an excess of neutrons over the background flux corresponding to the catastrophic fracture of a granite block subject to compression. Here we show that these measurements contain large inconsistencies with respect to the stated experimental procedure, including fractional neutron counts and strongly non Poissonian statistics
