McCANN


West called to him and he insisted on returning to Berkeley where he died in February, 1906, apparently from slowly advancing tuberculosis.

This is an outline of his brief life in which each turning was directed by his illnesses. -In his harness to the end, he cheerily though falteringly tested the effects of various drugs on jelly- fish when from his weakness he could no longer control a rabbit, and the paper on these experiments which his mother wrote at his dictation was published after his death.

He was indefatigable in his interest in his work and worked as an artist with a grasp of his problem. Through- out his crippled life he bore himself with the courage and cheerfulness Avhich stood so well by Stevenson.

McCann, James (1837-1893).

About the year 1825 a certain Thomas McCann of Scotch-Irish ancestry married one Sarah Wilson and settled on a farm near Verona, Penn township, Allegheny County, Pennsylvania, and on this farm James McCann was born April 12, 1837. His education was obtained in the public schools in which, at the completion of his course, he served as teacher for one or two years, after w-hich he entered at Cannonsburg, Pennsylvania, but termi- nated his studies before graduating.

About 1858 or 1859 he went to Pitts- burg and for a time was employed at clerical work; later becoming a student of medicine under Dr. John Dickson, before attending medical lectures in the Univers- ity of Pennsj'lvania. He did not, however, complete his studies at the University I at this time, but entered the Union Army
