and laborious one, involving many weighings of a deliquescent substance, which had to be done with the greatest rapidity, and at the same time with accuracy; also the making of some fifty careful assays, giving the chemist nearly a month of hard and dirty work. Another question referred to the chemist through Mr. Rhees, of the Institution, was the character of the coloring matter used on the small squares of paper given to the children in the Kindergarten schools of the District and elsewhere. This paper is a thin paper, colored and glazed on one side (in most cases), cut into five-inch squares, and is given to the children to cut up and fashion into various patterns.

The chemist regrets that he has not been able to find time to make more than a brief qualitative examination of the subject. Eighteen samples of paper were 'tested for arsenic, and out of that number six samples were found to contain a large amount of arsenic in different forms, probably the most dangerous being a bright green paper, the coloring matter being the brilliant but deadly Scheele's green. The other colors found to contain arsenic were purple, solferino, navy blue, carmine red, and vermillion red. Another investigation undertaken by the chemist for prominent private parties was a thorough testing of the so-called Robertson electric process for the reduction of gold ores. This process, like the Tichnor, is utterly at variance with accepted ideas of chemists and metallurgists, and the investigation showed similar results to the Tichnor in proving it of little value. In addition to these investigations the chemist has undertaken numerous analyses and assays for private parties of no particular chemical interest. The time of the chemist has of late been entirely occupied in overhauling and recording the vast amount of reserve material stored in the Institution, the object being to make a complete record of duplicates and reserves and to eliminate all worthless material and make room for new contributions.
