AN ABNORMAL SALAMANDER. 
(Explanation of Figures.) 
E. B. Williamson. 
Mr. John Russi during the past summer collected a newt, 
Diemyctelus viridescens, Raf. , n:ar Salem, Ohio, with a fifth 
foot growing from the dorsal surface of the left thigh, as shown 
in figure 1. The newt is a young one, 48 millimeters in length. 
The left femur is slightly longer than the right, and is shown 
much enlarged at figure 2 in anterior view. Near its middle is 
a section of cartilege which allows of the femur being bent 
slightly in any direction. Tendons from the fifth foot pass to 
the femur at this point. Figure 3 shows a much enlarged draw- 
ing of the skeletal elements of the foot from dorsal view. The 
salamander was kept alive for 'some time but so far as was seen 
made no use of and exercised no control over its extra foot. I 
am indebted to Mr. Russi for the privilege of examining this 
interesting specimen which he has donated to the Salem High 
School Museum. 
THE SUMMER’S WORK AT SANDUSKY. 
The work at the Lake Laboratory at Sandusky the past sum-

and students from the Departments of Botany and Zoology and 
Entomology of the University, there were in attendance repre- 
sentatives of a number of other Ohio colleges and high schools. 
Courses in General Zoology, Botany, Entomology, Invertebrate 
Morphology, Embryology and Ornithology were given. Collect- 
ing trips to different portions of the bay, the lake shore, and the
