John B. Adams, esq., died at his residence, at the West End, about 7 p.m. yesterday. He had long suffered with a pulmonary affection, which he bore with Christian fortitude until relieved by death. He leaves a widow and four orphan children to lament his loss.

He was born in Crawford county, Illinois, in 1830, and was nearly forty years of age. He removed to this city in 1858, and took an important position in the banking department of the office of Hon. J. K. Dubois, then auditor of state. This position Mr. Adams continued to hold - Mr. Dubois being elected to a second term - until 1864, to the great satisfaction of all who had business with that department. It will be remembered that during this period nearly all the state banks of Illinois were placed in liquidation, and a large part of the business passed through Mr. Adams' hands. It is sufficient to say that so far as possible all the interests of the bill holders and stockholders were carefully protected.

Leaving the auditor's office, Mr. Adams formed a partnership with Major D. L. Gold, and opened a drug store in 1865. He attended to this business until 1868, when his failing health admonished him of the necessity of a change of business. Since then, with many fluctuations, his disease has been making constant progress. Mr. Adams has been for some years a faithful, consistent member of the Third Presbyterian church.

His family, his many friends and his brothers of the church will meet at his late residence tomorrow to pay the last tribute of respect to his remains.
