Abnormal microscopic findings in organs which appear normal grossly, such as the kidney, pancreas, and adrenal glands have been recently reported in cases of trisomia.1

It was to be expected that a microscopic study of the CNS by the conventional celloidin technique on large sections would yield findings which might be missed in the smaller sections from paraffin blocks as customarily prepared in the tissue laboratories of pathologists. Whereas such striking anomalies as the absence of olfactory nerves and tracts,
