This species was discovered in the following manner. Parker's paper, in which, by the way, he departs from the very common practice of giving merely dry details of ■perinl characteristics of genera and species, and di Bcusses instead the broader principles of construction exhibited as mnch in variation of form as in unity of design. A few days ago, I purchased a lobster taken off the Creaswell coast, nine miles to the east of Morpeth, not br fi^m low-water mark, where the sea bottom is covered with flat rocks and the larger Algae luxuriant. The paper is illustrated with very numerous and beauti- fidly executed drawings and diagrams, which testify to the industry as well as the talent of the author ; and I am much mistaken if this communication does not act as a powerful stimulus to enlist a large number of microscopical labourers into BO promising a field of scientific reeearch. One of these villous tufts I have mounted for your I iu Biicction (fig. Brightwell, in a communicatiou on the ^filunentous long-homed Diatomacc«, describes two species ef these singtilar Algse as the first which have been, iu a Kriiig state, discovered in this coimtry : these are Clueta- wro« Wighamii, gathered by Mr. The anterior extre- mities appear in the form of small fins or paddles, while the lower ore discernible aa buds projecting from cither side of the trunk. Blenkius minutely describes the appearance of the allantois, and corroborates tlie p^e^■iou B observations of \Vagner, Miiller, Coste, and others : be also remarks upon the vitelline sac, the chorion, and amnion, which two latter integuments, unlike Dr. Parker, "On the Milio Utida; of the East Iftdian Seas." If I Eun not mistaken, this is only the fourth paper rc- ' lating to the Foraminifcra that has been laid before the Microscopical Society since its formation ; and I confess that it is a matter of very considerable surprise to me, that a class of bodies of so highly interesting a nature, resperting wliicb Thv Pregideitft Address. 2), and it will be seen that they are hollow I canals, their walls being composed of granular cells, and f having numerous pouch-bke projections from them, or rudi- meiitary villi; one of the primary divisions of this tuft is partially broken aerosa, and you will notice distinctly that it 18 empty.

Brightwell's comraunica- tion, no other native member of the family has, I believe, been discovered. Farre, he finds separate, and is unable to find a trace of any vessels in the villi of the chorion. Cobbold, though at first inc Uned to regard this species aa allied to some of the echinoderm larvffi described by Muller, subsequently hazards an opinion that it might be more properly classed amongst the Polyzoa, but states, that on commumcating this opinion to Professor Allman, that gentleman in reply considers that Dr. The concluding paper belonging to this section is one we had the pleasure of hearing read at our last meeting, and is by Mr. 69 tliere is eo wide a field open fur i Dvesttgation, aad that ii by no means difficult of acquisition, seeing that many of the 8pei-ic9 are very widely distributed, should not command the sf Hrcial attention of a much larger number of workers. Carpenter and Professor Williamson as peculiarly devoted to these singular beings, we are mentioning a host in tliemselvcs; but great generals require the aid of multitudes of humbler assistants, and if we cannot all aspire to become officers in the army of investiga- tion, many of us may do much service in the ranks.

Arthur Farre ; and one " On an early Human Ovum," by Mr. In each of these cases, the precise age of the aborted spe- cimens was not capable of accurate determination, but the respective authors of the papers estimate, from careful eom- panson with specimens ol' known age, that tlie lirst-uamed was voided alrout the early part of the fourth week of utero- geatatiou, while the latter was probably a fen days younger. Parre regrets that, in onler to avoid injuring the cephalic portion of the embryo, when opening the sac, he cut through the pedicle of attachment, and was thus unable to give aity satisfactory account of the allantois ; while in the specimen operated upon by Mr. Qnekett*s paper on the White Filamentous Substance surrounding the so-called Mealy Bug of the Vine.

After sub- jecting the contents of this lobster's stomach to the action of Twiling nitric acid for several minutes in a small retort, and alter removing the acid from the remaining sediment by re- peated ablutions with distilled water, 1 was not a little astonislied to discover on all the slides — on which a portion this sediment was placed — several specimens of Synden- 'ium diadema ; its frustules being more numerous than B of any other diatom. tain by future investigation) ; and if ho, which I httle doubt, it will materially assiat, by the facility offered for the study of its living form and economy, in solving the question as to whether the group, to which it belongs, ought to be classed amongst the Diatomaceee, irom which it has been excluded by Professor Smith in hia recent ' Synopsis,' and by others, a& of a doubtful character. 1 now proceed to consider the one paper that I have classed u pathological, which might with almost equal propriety have been included amongst the botanical ; it is by Mr.
From this fact it would appear, this remarkable form is quite common on this part of Northumbrian coast (but this I mean shortly to ascer- i L. It will also assist in determining whether those various species of the same family, hitherto observed only in a fossil or semi-fossil condition, have in the living state their frustulea aggregated into filaments,- or whether these exist as sepjwate and independent organisms. drove, and entitled, "On a Fungus parasitic in the Human Ear."

Ill eonclnsion, I fenr 1 must apologise to tlie non-profes- eimial portion of my audience for the introduction of such dry details, on a subject which they cannot be expected to l)e very familiar with, and to some of whom they may ap|icar ulto- I gether unintelligible ; but as we medical members of the t Society have been renmrtcd aa not pcribrmiiig otir share in I ita business, and as 1 pi'rsoually feel the imputation to be a I just one, 1 have ventured to lay before you these few remarks, 1 whicli tlio esamtnation of this ovum has aifonled rae the opportunity of making, in order to show that 1 am desirous I of contributing my mite whenever 1 have the means of I doing BO. Within the last few days, however, it has fallen to my lot to discover a third species in a recent condition, which, if I am not mistaken, has hitherto been found only in a fossil state in certain diatomaeeous earths, and in the guano de- posit on the coast of Peru ; from which it appears to possess B very wide geograpliical range. The two specimens, I would remark, differ materially in the point of size, although so nearly of an age ; but this is by no means surprising, when we recall the great variation in size apparent in different children at the period of birth. Spencer Cobbold, " On a probably New Species or Form of Actinotrocha, from the Frith of Forth." The observations that were made, though few, are impor- tant, as they go far to demonstrate a distinct specific differ- ence from the Ac Hnolrocka branchiala of Miiller, as was apparent from inspection of an example of the latter species in the possession of Dr. A solution of the mystery may probably be found in the fact, that the determination of the limits of each species in this class of organisms is by no means an easy task, as is appa- rent from the observations of Dr.
