During the past few years thallium has come to assume a much more important position among the elements. A prime cause of this phenomenon was the second world war and its unforseen demands for materials possessing special properties which could be put to use in an attempt to further the war effort. Recourse was made to thallium probably because of its similarity to lead and much was added to the limited knowledge of the element. It was only logical then that new and better methods of analysis of thallium should be sought, since use of any substance will at some time or other require an accurate method for its analysis. New ways for determining thallium were devised and these along with older methods of analysis afforded the chemist a variety of ways in which to compute the amount of thallium present in a particular substance. It is the writer's belief, however, that in such a situation one procedure must be superior to the others with regard to accuracy, precision and ease of manipulation. The problem is to find which one this might be. Statistics affords the chemist an accurate and sure means for making this decision. A statistical study of the accumulated procedures will be made in this thesis in an attempt to decide which of the several methods for quantitatively analyzing the thallous ion is the best qualified to do the job.
