been called, has been found in England. In structure this animal re- 

 sembled the fallow deer, but was larger. The remains of a cervus, 

 not differing from the red deer, were frequently found with the mam- 

 moth and other animals. Remains also of the roebuck, and the goat 

 and sheep, had been found associated with those of the mammoth. Re- 

 mains of the aurocks or European bison, had been found in various 

 parts of England, and also of Ireland. According to Mr. Ball, these 

 remains should be looked upon as those of an extinct species. In con- 

 cluding his Report, Prof Owen stated, that he never should have com- 

 menced these labors, nor could he have continued them, but for the 

 suggestions and assistance of the British Association.

Are the Atomic Weights multiples of the equivalent of Hydrogen 7 — 

 It is known that the opinion advanced by Prout, that the atomic weights 

 of all simple bodies are entire multiples of the equivalent of hydrogen, 

 was abandoned when Turner arrived at a negative result after a se- 

 ries of experiments, with which he had been charged by the British 

 Association for the Advancement of Science. It is also recollected 

 that M. Dumas revived this opinion by his experiments to determine 

 the exact atomic weight of carbon, having found it exactly twelve 

 times that of hydrogen. M. M. Erdman and Marchand have repeated 

 and confirmed his experiments. In waiting farther research, it would 

 appear that M. Dumas's experiments confirmed by the German chem- 

 ists have not been executed with all the care requisite, and that proba- 

 bly a certain agreement between the experiments and a preconceived 

 opinion of the authors, had blinded them somewhat to certain minute 

 precautions necessary in the process. One might almost believe that 

 M. Dumas has tried by a single dash of the pen to cast a suspicion of 

 inaccuracy upon all the careful and arduous researches of those who 

 have advanced a different opinion concerning the atomic weight of 



* Messrs. Editors, — This is but a hasty notice of some of the important articles 

 contained in the Report of Bezelius, and given in almost all cases in the words of 

 the author; those of your readers who have an opportunity to refer to it I 

 would recommend them to do so. A tolerably complete sketch is given of what 

 has been done upon the subject of atomic weights, which goes to show that Front's 

 theory is as doubtful as ever. Yours, J. L. S.
