700 Chronicles of Science. [Oct., 



resuscitation, under the limitations named, is a possible process, and 

 that it demands only the elements of time, experiment, and patience 

 for its development into a demonstrable fact in modern science. We 

 have not space to follow Dr. Bichardson through the systematic series 

 of experiments which lead to this result, but we may add, that the 

 present memoir is preliminary, and that he promises to return with 

 new results which are in course of development. One very remarkable 

 circumstance may be recorded, which in the author's words is as 

 follows : — " Since this paper was laid before the Society I have deter- 

 mined, by a direct experiment, that rhythmic stroke is of the first 

 importance (in artificial circulation) for restoring muscular contraction. 

 By means of a machine, which can be worked either by the hand or by 

 electro-magnetism, I was enabled, assisted by my friends Drs. Wood 

 and Sedge wick, to introduce blood heated to 90° Fahr. into the coronary 

 arteries of a dog by rhythmic stroke, and at the same rate as the stroke 

 of the heart of the animal previously to its death. The result was 

 that in one hour and five minutes after the complete death of the 

 animal, its heart, perfectly still, cold and partly rigid, relaxed, and 

 exhibited for twenty minutes active muscular motion, auricular and 

 ventricular. The action, which continued for a short time after the 

 rhythmic injection was withheld, was renewed several times by simply 

 re-establishing the injection. 



Mr. Blyth, writing to the ' Natural History Review,' gives some 

 remarkable instances of the reappearance of lions in some parts of 

 India, from which they were supposed to be extirpated. He observes 

 that during the whole of his twenty-two years' residence in India, 

 not a single instance had been recorded of a Hon having been observed 

 in any part of the country, excepting in the province of Kattywar, 

 in the peninsula of Guzerat, to which locality, in the general opinion 

 of sportsmen and others, the species is now restricted as an Indian 

 animal. The lion was supposed to be extirpated in Harriana in 1824 ; 

 one was killed in the Nerbudda territory so late as 1847-8 ; since 

 which it does not appear to have been heard of in those parts until 

 last year, when in August, Lieut. Clarke, R.A., was out shooting near 

 Dusay, on the borders of Eajpootana, and was sadly mangled by a 

 lioness, and had to suffer amputation of his right arm. Later, in 1865, 

 March 19th, Lieut. -Col. Tytler writes that a party of officers were out 

 shooting small game on foot, when to their horror three lions sprang 

 out before them, two males and a female. They fired : one of the 

 males fell dead and the other wounded, and was found dead next day. 

 Lions had not been heard of in that part of the country for at least 

 thirty years. 



Dr. Davy, in the Proceedings of the Eoyal Society, gives the 

 results of his observations upon the temperature of the common fowl, 

 made at different seasons of the year, showing that the temperature 

 of this bird ranges from 107° to 109°, and that the male possesses a 

 somewhat higher temperature than the female. Hunter assigned to 

 it a temperature no higher than between 103° and 104°, a degree 

 reached and even exceeded by some mammals. He also gives the 

 results of his experiments on the air expired by a certain number of
