Pathological Report on Miscellaneous Specimens 
 
Red hepatization of almost the entire lobe of each lung in 
two young blue geese, nos. 21691 and 21692, constituted pathological 
evidence that pneumonia was the immediate cause of death of these 
birds. 'The' pneumonia was probably also the primary cause of death, 
as the birds bcame sick suddenly and died after a very short illness, 
and no evidence of another disease could be detected at necropsy. A 
species of Salmonella was obtained in pure culture from the lung of 
one of the birds. Injection of lung tissue from this bird into a 
normal mallard duck failed to reproduce pneumonia.

An immature robin, no. 21695., found sick in Minneapolis was 
turned in to the Minnoap!olis Public Library Science F-sojum t i later 
was forwardep to us. Complete spastic paralysis of the logs of tVLs 
bird was ascribed to some u nper motor neuron lesion. Lhe diagnosis 
was confirmed.at necropsy two days later, when a traumatic lesion 
was found just anterior to the sacrum. An old hemorrhage in the lungs: 
was probably also cau{sed by trauma. The cloaca Was' enormously dilated 
from loss of sphincter control.
