Página 363 - It is well to observe, that neither in these nor in other poisoneaters is there the least trace of an arsenic cachexy discernible ; that the symptoms of a chronic arsenical poisoning never show themselves in individuals who adapt the dose to their constitution, even although that dose should be considerable. It is not less worthy of remark, however, that when, either from inability to obtain the acid, or from any other cause, the perilous indulgence is stopped, symptoms of illness are sure to appear,...

Accordingly, whilst in the steam engine the caloric is constantly wasted by being passed into the condenser, or by being carried off into the atmosphere, in the improved engine, the caloric is employed over and over again, enabling me to dispense with the employment of combustibles,...

After sixty years of renewed inquiry, and after we have greatly enlarged the sphere of our knowledge, the same conclusion seems to me to hold true. But if any one should appeal to such results in support of the doctrine of an eternal succession, I may reply that the evidence has become more and more...
Página 224 - Playfair, we have given the result of some examinations of stalactites from caverns in Germany, and from the vaults of old castles upon the Rhine, made with the view of ascertaining the fact of the presence or absence of organic matter in these bodies, either combined or uncombined. The result may be 'stated in the words of the author, Prof. LIEBIG : The stalactites from the caverns " contain no trace of vegetable matter, and no humic acid, and may be heated to redness without becoming black.
