On Plant Pathology and Bacti-riology 131 



That year Scribncr in his (xipcr on "* Hlack Rot" '-' read before 

 the Society for the Promotion of Agricultural Science mentioned 

 Smith's work on the ascosporous form of the fungus. Smith, in 

 Washington, roomed at the home of Benjamin Pickman Mann, 

 assistant entomologist of the Department of Agriculture, a lin- 

 guist conversant with "as many as ten languages," ''° who knew 

 botany having taught the subject for a year at Bowdoin College 

 and at one time edited a catalogue of the phaenogamous plants of 

 the United States, and who later was an examiner of the federal 

 patent office. He was the son of Horace and Mary Peabody Mann, 

 a graduate of Harvard University, member of national and local 

 scientific societies of Cambridge and Washington, a bibliographer, 

 author, philanthropist, and Unitarian, whom Smith esteemed al- 

 ways as " an upright and useful citizen." 



In the same home roomed a young doctor of medicine, Theo- 

 bald Smith, director of the pathological laboratory of the Depart- 

 ment's Bureau of Animal Industry. In 1881 he had been gradu- 

 ated from Cornell University with the degree of Bachelor of 

 Philosophy, and in 1883 obtained his medical degree in the city 

 of his birth at Albany Medical College. During a spring semester 

 while a medical student, he had studied in the biological labora- 

 tories of Johns Hopkins University; and, after securing his degree, 

 had taken some graduate w^ork at Cornell.^-' 



At Johns Hopkins courses of instruction in biology and physi- 

 olog)^ were given by the able and distinguished English biologist, 

 Henry Newell Martin, a man imbued with the teachings of 

 Thomas Henry Huxley, and by William Keith Brooks, a graduate 

 of Hobart and Williams Colleges who had taken special work 

 with, among other eminent scientists, Louis and Alexander 

 Agassiz.^-^ W. T. Sedgwick'-^ was then an associate in the de- 

 partment. Going to Johns Hopkins with E. B. Wilson, each 

 having been granted fellowships, Sedgwick had been persuaded by
