Another objection has also been advanced against the employment of ether or chloroform, the force of which must be estimated by every one for themselves. It is well known that many, if not most of the lower animals during labor, or immediately afterward, _experience certain feelings and desires stronger than at any other time_; and it is supposed that such would be the case, as a general rule, with human beings, if it were not for the _pain_ which overpowers everything else. This supposition has, in fact, been partly verified in a few cases; several females having confessed, after recovering from a painless labor under the influence of ether, that their dreams during the sleep were of _a peculiar warm character_! How far this may be _generally_ the case, of course, we have no means of ascertaining, nor do I consider it to be practically of any consequence to know, because it can in no way interfere with the safe progress and termination of the labor, which alone is what we are properly concerned in. I have merely thought it proper to state the fact as being a singular one, and to make my readers acquainted with it. Physicians are well aware that the peculiar feelings referred to are frequently produced by various causes which act on the nervous system, such as _mesmerism_, and even by _strong devotional excitement_. I have known females with strong moral impressions who always carefully avoided _both_ the above causes, from having discovered their liability to produce such effects; in fact, this has been one objection raised to allowing mesmerists to operate upon young persons, and several cases of moral failing having been attributed to this cause. It is not at all improbable, therefore, that such results may occasionally occur during labor, though we are not at all justified in assuming that they will in any particular case. How far this may be considered an objection to the employment of such means, must be however, as I before remarked, decided by all persons _for themselves_, and _for themselves only_! It is not a _medical_ question at all. Notices of Dr. Hollick's Lectures. DR. HOLLICK AND PHYSIOLOGY.--The second of a series of Lectures, by this gentleman, on human physiology, and the all important truths connected with our physical constitution, was attended by a full house, in National Hall, last evening. The time was well spent, and so appeared to think the audience. On the delivery of the first of these Lectures on Tuesday evening, the speaker in a comprehensive and well-digested exordium, placed himself and the subject right with the public. His manner, language and style, did the first; his sound logic, his argument, his candor and research, accomplished the second. Apart from the interesting and apposite details of the wonders of reproduction, the illustrations of the immutable wisdom of nature, which teem in the animal and vegetable worlds--which
