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 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.

I must beg leave at the outset to acknowledge the valuable aid of my Assistant, Mr. R. B. Moris, F .C. S., in the present inquiry. An investigation of this kind, necessitating much consideration, can only be carried to a successful issue by arguments and discussions, and to Mr. Moris much credit is due for the light these discussions have shed on the inquiry; I feel also indebted to him for the care he has bestowed on the numerous analyses he has made for me, and for the accuracy with which-his work has invariably been done. From a general view of the function of respiration it follows that there are four fundamental forms of breathing; their characters are the following:—

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.

On August 4, 1893, at 6.41 p. m. (G. M. T.), an earthquake shock was felt throughout the whole of Leicestershire and Rutland, and in parts also of the adjoining counties of Lincoln, Nottingham, Derby, Stafford, Warwick and Northampton. The disturbed area, therefore, lies entirely within the land. It is also one over which villages and country houses are for the most part closely scattered, and it has thus been possible to obtain a large number of careful and detailed accounts. I have received altogether 391 records from 298 places where the earthquake was observed, and 103 others from 97 places where, so far as known, no trace of it was perceived.
