Note 1 — INTRODUCTORY REMARKS.

I trust the public will pardon me for stating, that various scientific friends, despairing of the revival of the Journal of Dr. Bruce, had, for some time, pressed me to undertake the editing of a Journal of Science. Considerations of personal friendship prevented me from listening to such proposals till the decline of Dr. Bruce's health, attended by the most alarming symptoms, rendered it very obvious that his Journal would not be revived. Towards the close of last November, in a personal interview, I communicated to him the design of the present work, at the same time offering to waive it, provided he considered it as probable that his own Journal would be resumed. Of this, however, he gave no encouragement; but, on the contrary, expressed his warm approbation of my undertaking, authorized me to consider him as a contributor, and to make public use of his name as a patron. It was not till after this that the annunciation of this work took place; and it is certain that had not all hope of the resumption of Dr. Bruce's Journal been completely cut off, this would not have appeared.
