Solution is generally best effected in flasks; but where the resulting liquid has afterwards to be evaporated to dryness and ignited, evaporating dishes (fig. 12) are used. With them clock glasses are used as covers during solution to avoid loss through effervescence. Evaporating dishes are also best when an insoluble residue has to be collected, since it is difficult to wash out most residues from a flask. Bumping occurs less frequently in dishes than in flasks. After the addition of the acid, and mixing by agitation, the vessel containing the substance is heated. This is best done on the "hot plate" (fig. 13). This consists of a slab of cast iron about half or three-quarters of an inch thick, supported on loose fire bricks, and heated by two or three ring burners (figs. 14 and 15). The burners are connected to the gas supply by means of _lead_ tubing, to which they are soldered. Flasks and dishes after being put on the plate are not further handled until solution is complete or the evaporation is carried to dryness. The hot plate is contained in a cupboard so as to be out of the reach of cold draughts. |
The uncertainties which hung over his presence in the earlier periods, spoken of in the former chapter, do not apply to the proofs of his presence during this age, though it is far from settled at what particular portion of the Glacial Age he came into Europe. We must remember we are to investigate the past, and to awaken an interest in the history of a people who trod this earth in ages long ago. The evidence on which we establish a history of the early tribes of Europe is necessarily fragmentary, but still a portion here and a piece there are found to form one whole, and enable us to form quite a vivid conception of manners and times now very far remote. |

The Connecticut Valley was next the theatre of war. Springfield, Hatfield, Deerfield, and Northfield were attacked the last two having to be abandoned. At Hadley the onset occurred on a fast-day. The men rushed from their worship with their muskets, which were ready to hand in church, and hastily formed for battle. Bewildered by the unexpected assault, they were on the point of yielding, when, according to tradition, an aged hero with long beard and queer clothing appeared, placed himself at their head and directed their movements. His evident acquaintance with fighting restored order and courage. The savages were driven pell-mell out of town, but the pursuers looked in vain for their deliverer. If the account is correct, it was the regicide, General Goffe, who had been a secret guest in the house of the Rev. Mr. Russell. He could not in such danger refrain from engaging once again, as he had so often done during the Civil War in England, in the defence of God's people. | ||
