Excerpt from The Elements of Experimental Chemistry, Vol. 3 of 3 No blame attaches to the publisher for not having originally delayed the republication, until the appearance of the new Eu glish edition, since the demands for the work were so urgent, as well by the students of the University of Pennsylvania, in which it is used as a text book, as by those of other public Insti, tutions, as not to admit of being disregarded. At the same time, in presenting the new matter in a separate form, he believes he has done an acceptable service, both to the purchasers of that part of his edition, already sold, by enabling them to complete their copies with the supplementary volume, and also to those, who, while they may desire to see the latest discoveries in Chemical Science, may not wish to incur the expense of the English copy.
