Notice of Walter H. Biillocli. 



By henry L. TOLMAN, 



CHICAGO, ILL. 



The death of this eminent Chicago microscope maker is a severe loss, 

 not only to the Illinois State Society, of which he was for nearly twenty 

 years a prominent member, but to the cause of science at large. He 

 was born in 1S35, at Glasgow, Scotland, and lived there until he was 

 seventeen years of age. About 18^2 the family emigrated to New 

 York, where Walter learned the trade of tailor with his father. But 

 his innate fondness for mechanical pursuits made him dissatisfied with 

 his prospects, and he was apprenticed to Messrs. Pike & Sons, then a 

 leading firm of opticians and instrument makers on Broadway, New 

 York city. After serving his time he went into business until the war 

 of the rebellion broke out. when he enlisted as a private in the 12th 

 N. Y. volunteers. His term of service, however, was very short, as 

 he contracted a severe cold, which developed into rheumatism, and he 

 was incapacitated from further work, and was mustered out of service. 

 Returning to New York he formed a partnership with William Wales, 

 the well-known maker of objectives, and continued in business there 

 until 1866, when he moved to Chicago. He was very successful and 

 had accumulated considerable means, when his shop and tools were 

 destroyed in the memorable Chicago fire of Oct. 8 and 9, 1871, and 

 Mr. Bulloch sustained a financial loss from which he never recovered. 

 Immediately after this misfortune, he went to Boston and was for a 

 time connected with the late R. B. Tolles, but again returned to estab- 

 lish himself in Chicago. In 1 889 he accepted a position connected with 

 the U. S. Coast and Geodetic vSurvey in the Bureau of Weights and 

 Measures, at Washington, but he chafed under the restraints of an 

 official situation, and after six months' experience, returned to his home
