A CASE oF MicrocEPHALY. By D. W. DENNIs. 
The subject of this sketch is Edward Basse. He is an inmate of the 
Institution for Feeble-Minded Children at Fort Wayne, Ind. He was born 
July 13th, 1883, in Germany. His father died at the age of 49. His mother 
lives at Garrett, DeKalb County, Ind. He is the sixth child of a family 
of eight children.. Of these six are said to be well formed. One other, 
Mary, who died at the same institution at the age of fourteen, in 1895, 
was microcephalic. His parents were second cousins. The following 
table gives the size of the cranial portion of his head in comparison with 
nine other microcephals reported by Carl Vogt in 1866:

It will be seen by the table that Basse ranks fourth in the list by three 
of his measurements and third by one. His measures are all very close 
to those of Michael Sohn and Conrad Schuttelndreyer, whose skull-con- 
tents were 370 ¢. ¢ The measurements taken on Sohn and Schutteln- 
dreyer were taken from the skull, however, while the measurements of 
Basse were taken from the living head covered with thick and not closely 
cut hair. 
Several factors not represented by maximum measurements affect the 
cubie contents of the skull: the shape of the floor, the amount of surface 
for which maximum thickness stands, the thickness of the bones, ete. The 
second of these factors is against the size of Basse’s cranial capacity being 
large, for the maximum is in the region just over the ear, while the frontal 
and post-parietal and occipital lobes fall rapidly off. I do not think his 
cranial capacity can be more than 400 c. ¢« The normal capacity of a
