 rose, amongst the expansions of the olfactory nerve, I found eight other specimens, all of which were males. I then examined the auditory canals, but no traces of the parasite were to be seen, I immediately prepared same of them as specimens for the microscope, thinking that if 1 could keep the young alive in situ until the next meeting of the Birmingham Natural History and Microscopical Society, when Mr. W. R. Hughes, F.L.S., was to present a paper on an allied subject by Dr. T. Spencer Cobbold, I might, perhaps, assist In throwing light on a matter of considerable difficulty, one which has occupied the minds of some of the most distinguished scientific observers for years past, and which is now bearing fruit in the shape of contributions of a character so important to the medical and non-medical world, that I feel bound to express my personal obligation to Dr. Cobbold for the very complete form in which he is bringing the subject before the Society and general science-loving public. The mounted specimens were exhibited at that meeting, immediately after Dr. Cobhold's paper. The young worms were then alive, as was testified by Mr. Hughes himself and several others, having then been mounted in Canada balsam for four days, showing the extreme vitality of these young minute threads of living matter. I have written to Dr. Cobbold, and sent him specimens for examination, and until I hear from him, with his declaration as to the name of species of this round worm, I must defer my anatomical description. It may turn out to be a well-known form. If it does, no descriptions will he necessary; but way departure from the usual form will be noted and described. The worm, and the skull showing the sinuses, may be seen at Mr, Bolton's Studio, No. 17, Ann Street, Birmingham, where I have placed them for inspection.—Wright Wilson, M.R.C.S., F.L.S., &c.

.—We heave much pleasure in announcing that at the annual meeting of the Woolhope Naturalists’ Field Club at Hereford, on the 23rd April, it was unanimously resolved that the Club join the Midland Union of Natural History Societies.

.—Under this title a valuable book by Mr. Montage Browne, of Birmingham, has recently been published at "The Bazaar" Office, London. In an early number we hope to review it at length.

.—In the March number of the "Journal of Botany" Professor Babington commenced a series of articles "Notes on Rubi." In the March and April numbers are criticisms on little understood forms, which will be read with interest end instruction by all students of this difficult genus.

.—In the "Quarterly Journal of Microscopical Science" for April a valuable contribution appears, entitled "Recent Researches into the Nature of Lichens," by Sydney H. Vines, Fellow and Lecturer of Christ's College, Cambridge, in which the more recent speculations for and against the Algoid Nature of Lichens are given, and very ably criticised.

fasciculus of seventy-five specimens, representing sixty species, illustrative of "Carrington's British Hepaticæ," will be ready for distribution on 1st June next. Communications should be addressed to Mr. W. H. Pearson, 145, Church Street, Pendleton, Manchester.
 * —Students of these interesting plants will be glad to see by an announcement on cover of present month's number, that a
