 the First Class, First Part of the Natural Science Tripos, 

 and, in 1886, in the Second Class of the Second Part. He 

 came as Science Master to the Hulme Grammar School, in 

 April, 1888. As a schoolmaster he was a marked success,

 work, and his thoroughly unselfish nature made him a 

 universal favourite. After a short illness, he succumbed to 

 an attack of pneumonia on Sunday, March 8th, 1891.
