"Development of the rabbit heart after the plate models of Gistav Born. Born claimed that his plate method was more objective then His's 'free' modelling. The walls of the atria and vessels have been modelled somewhat thicker and more distinct, respectively, than they in fact appeared. Magnification 60-fold throughout." Hopwood, Nick. Embryos in wax.
