Résumé
See Patent Office Reports for 1850.5 they are pending, he becomes intimate with the speculators and holders of the licence, and announces that it is Coal !To the man of science the material is asphaltum ; to the hungry schemist it is changed first into Asphaltic Coal, and then intoCoalitself.The truth and correctness of Dr. Jackson's present statements are denied by the Academy of Natural Sciences of Philadelphia, tlie Polytechnic Institution of London, the late lUchard C. Taylor, Dr. Ure, and many more of the most eminent scientific men of the age.The decision of those public bodies, and a number of certificates from distinguished individuals, will appear at the close of this Review.We therefore turn to Dr. Jackson's Reports in the spirit of candid examination, to inquire how far he has supplied any reason for his extraordinary vacillancy ; but no motive can be found for his self- condemning paper, except one, which will be as well understood as if it had been expressed.After giving a full account of his exami- nations, our author states that his subject " has embarrassed men highly distinguished in the ranks of science," who, under " erroneous impressions," have attributed to **hisco<2Z" properties which it does not possess, but which belong to coal-tar, fitch, and asphaltum.Such men therefore, according to his statements, cannot distinguish between coal, coal-tar, pitch, and asphaltum; this kind of discernment being only possessed by himself, or other persons having an interest in the mine of Hillsboro'.Employing for the moment his own words, taken from the pub- lished declarations and analysis of Dr. Jackson himself, and the united testimony of many distinguished persons, " I shall be able to prove, to the satisfaction of all scientific men, that the Albert Asphal- tum is in true veins, included in asphaltic shales ; and from the absence of the fossils that accompany coal, and the presence of those that belong to other formations, the veins are not in a coal field, and are of more recent origin than the rocks that embrace them." I shall next show conclusively," and that by Dr. Jackson's own analysis, *' that the substance in question is really" Asphaltum, of an unusually "beautiful variety ;" (his own words again) and that ** it cannot be confounded with Coal, and will not serve for the uses to which that substance is applied ;" so that neither in a scientific or practical point of view is it any variety of Coal.Dr. Jackson states, (page 4) that he also learned, by his own examination, that no such substance as soft asphaltum or naptha is found in the Albert coal, or anywhere near it ; and then quotes a private letter from Dr. Gesner, which he endeavors to make it appear was written to mislead him.The letter of John Edgett, Esq.,* contained in this Review, will satisfy the reader that Dr. Jackson's assertions and suspicions are unfounded.At the fourth page of the Reports, Dr. Jackson relates, that *' some time after his analysis had been reported, in the spring of 1850," (at which time he called the article " a beautiful variety of * See Anuf' ^is,.' It softens and melts when exposed to heat in close vessels.When inflamed

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
