miting, and frequently in the diarrhoea of infants, with the happiest results. 

 An infusion of the leaves has proved an excellent remedy in hooping-cough, 

 and their use might be profitably extended to other derangements of the ner- 

 vous circulation. C. In the canton of Richmond, in America, there exists a 

 kind of clay which is sought by many persons, especially children, as food ; 

 Prof. Cotting has published an analysis of it, and found that 100 parts of it 

 furnish, silica 31, oxide of iron 12, alumina 34, magnesia 10, water 12, with 

 loss 1, and it presents vegetable without any trace of animal matters. 7- 

 Mr. Froriep addresses an appeal to physiologists, and we transcribe it here, 

 with a supplication to naturalists in behalf of the beetles and butterflies. 

 Man, the philozoist observes, may use animals, but he may not abuse them. 

 The necessity for instituting physiological experiments on living animals, we 

 do not deny ; but, for the sake ot humanity, we may be allowed earnestly to 

 entreat that, as soon as the object of the experiment admits, the animal may 

 be put to death. Very often do we see experiments performed on living 

 animals in cases where one just previously deprived of life would answer the 

 purpose quite as well ; and how frequently does it not happen that a muti- 

 lated creature is carelessly thrown away, and left to breathe out life, by slow 

 degrees, in the cruelest of tortures ! The writer once saw, in illustration of 

 a lecture, the heart of a frog laid bare and beating. Fourand-twenty hours 

 afterwards, he found the same animal on the same table, where it had been 

 carelessly left lying, its heart still beating ! If the sufferings of the poor 

 animal be not regarded, it may perhaps be worth considering whether there 

 may not be thus produced a hardening effect upon the minds of the youthful 

 pupils of science, and whether society at large may not suffer through the 

 consequences. If it be undesirable that a butcher should fill the office of a 

 juror in cases affecting life, this presupposes an obtundity of feeling ; and if 

 here the slaughtering and subsequent cutting-up of animals produce such an 

 effect, how much more must not the reckless dissection of living ones deprave 

 the heart, and render it incapable of sympathizing with suffering humanity ? 

 Among the original communications is a contribution, by Mr. Marshall, to 

 Statistics of the Mortality among Horses in Cavalry Corps serving in the 

 United Kingdom, together with the number of horses cast, and some preli- 

 minary observations respecting the selection, training, and feeding, of horses 

 belonging to dragoon regiments. This contribution proceeds from an intel- 

 ligent and observant medical officer : his remarks may be perused with ad- 

 vantage by fox-hunters, steeple-chasers, race-riders, by the whole tribe, 

 indeed, of those light-headed heroes who delight in the doings of the road, 

 the course, and the turf; and, entertaining this notion, we recommend it to 

 their especial consideration. There is a highly important and instructive 

 analysis of Mr. Colquhoun's report of the proceedings under a " brieve of 

 idiotry," with an appendix of relative documents, and an introduction : it 

 exhibits a compendious view of the law applicable to such cases, and forms 

 an excellent addition to the illustrations of medical jurisprudence. This 

 Journal continues the long series of periodical literature which commenced 

 at Edinburgh in 1731 ; and, while many cotemporaries or rivals have begun, 

 or changed, or terminated their career, this work maintains its uniform 

 course, exercising an influence, and conferring on the branches of science to 

 which it is devoted, a moral and intellectual dignity altogether unparalleled 

 in the records of philosophy.
