The spark spectrum of air as photographed, mapped, and described by Hartley and Adeney contains various lines which they have not been able to attribute to oxygen or to nitrogen, having no grounds for assigning them to one element or the other. The lines belonging to oxygen and nitrogen, when produced by uncondensed sparks, are comparatively well known; so also are the lines of oxygen when a condensed spark is used, but it is otherwise with the lines of nitrogen when the spark is condensed.

The two spectra of oxygen are shown to be of a different nature. They behave differently, and reasons are given for their being in all probability the spectra of different gases. They may either be two spectra produced by different vibrations of the oxygen molecule, or they may be the spectra of two different modifications of oxygen, or the spectra of two distinct gases resulting from a dissociation of oxygen, a combination of which is called oxygen. It appeared worth while to undertake experiments with a view of testing the last of these.

Since May, 1892, I have been making monthly determinations of the number of bacteria capable of development on a peptone-gelatine plate in a given volume of Thames water collected at the intakes of the Metropolitan water companies at Hampton. The number of microbes per cubic centimetre of water varied during this time between 631 and 56,630, the highest numbers having, as a rule, been found in winter or when the temperature of the water was low, and the lowest in summer or when the temperature was high.

In the 14th of the 'Lecons sur la Physiologie et la Pathologie du Système Nerveux,’ Claude Bernard draws attention by experiments on the frog and on puppies to the degree of impairment in movement undergone by a limb that has been rendered insensitive by section of the sensory roots of its spinal nerves. In a series of experiments carried out during the last eighteen months, we have examined the same thing in the monkey, using chiefly Macacus rhesus, and observing the animals for periods up to four months from the time of operation. We propose to give here a brief account of the results obtained.

In the last part of the paper the medical aspects of this research are discussed. I t is suggested that emotional syncope is due to paralysis of the splanchnic area, and a case is quoted where com pression of the abdomen immediately removed the syncopal condition. The same treatment, or that of elevation of the abdomen, is sug gested for conditions of shock, chloroform collapse, and after severe haemorrhage. Finally, a parallel is drawn between some of the results of this research in reference to monkeys and those obtained by Dr. George Oliver on man, by measuring the diameter of the radial artery with his ingenious instrument, the arteriometer.

Black-damp, sometimes also called choke-damp, or “stythe,” is one of the gases frequently found in the workings of coal mines. It is distinguished from fire-damp by the fact that it is not explosive when mixed with air, but extinguishes flame; and from after-damp by the fact that it is not the product of an explosion, but collects in the workings under ordinary conditions.
