is said to be equal to the best Swedish. The soil is rich and produces good 
crops of corn and wheat. The surface is undulat’ng, and covered with a thick 
carpet of buffalo grass that protects the soil from denudation. We find near 
Fort Harker large concretionary masses of fine sandstone. They are valuable 
for grindstones. Some of them are 20 feet in diameter, and where they rest on 
soft rock that has been fashioned into rude pillars by the elements, they resemble 
huge mushrooms. I trust Kansas will soon organize a thorough geological sur- 
vey. It is too bad that science must wait for private enterprise to develop the 
rich stores of animal and vegetable remains buried in the rocks of our great 
State. Already many rich collections have been taken out of the State to Yale 
College, Philadelphia, and other Eastern museums. Among the marine shells 
described by Prof. Meek are found Cressatellinz oblonza, Arca parallela, Yoldia 
microdonta, Cardium Kansensts, C. Salineus, Turbo mudziana, etc.

THE THERMOGRAPH: ITS EVOLUTION AND DESTINY. 
A. WELLINGTON ADAMS, M. D. 
[Dr. A. Wellington Adams, of Colorado Springs, has invented an apparatus 
for measuring the heat of the body for a given or an indefinite length of time, 
to which apparatus he gives the name of Thermograph. It is a very ingenious 
contrivance, and it is based upon the principles Breschet advocated. Medical 
men have long been plodding on with the ordinary medical thermometer, the best 
of them recording but one application to the body. It must be evident to every 
one in the medical profession, as well as those out of it, that any instrument that 
can so record the temperature that the medical man can enter the sick room, day 
or night, and see what the temperature of the body has been for any hour, half, 
or quarter hour of the twenty-four, we repeat, it must be evident, that such an in- 
strument must be of incalculable value to mankind. This Thermograph widens 
the field of the diagnostician and allows him to prognosticate more surely. 
There has long been a need for something which would register accurately 
the rise and fall of temperature during sickness, and the present system is sadly 
limited by the many imperfections and the very narrow range of its application, 
and we are glad of this addition to the mechanical appliances of medicine. In 
dealing with the force, electricity, Dr. Adams found many obstacles; the greatest 
were the proper condition of the conductive carbon under pressure and the fric- 
tion of the apparatus, the last by no means being the least. Also, by his studying 
the principles laid down by Breschet and Becquerel, Pere et Fils, he has succeeded 
in giving to the world his Thermograph, an instrument which will be a very val- 
uable auxiliary to physiological, therapeutical and pathological investigation. Dr.
