Annulate lamellae have been observed in the myocardium of 18-day-old chick embryos maintained at the normal temperature of 100 degrees F and at 90 degrees F during the last week of incubation. An increased number of annulate lamellae was observed in heart muscle of embryos incubated at 90 degrees F. This is probably caused by a persistent production of these organelles, since annulate lamellae are present in greater frequency than in 11-day-old embryos incubated at 100 degrees F.
