Figs. 4 and 5, highly magnified, seemed to me to be probably the embryo state of the Acarus above described. I would here note the great liability to disappointment that is incurred in the search for Acari in the tumours we have just considered. In illustration of this, I may remark that in many fresh slides I have altogether given up as hopeless the idea of discovering them, but that, on a subsequent occasion, I have on examination found them to possess some one, others two, and others again three of these creatures, with perhaps some oval bodies resembling the embryo stage of the same. Again, some fe\v refused to discO\'er any to the most careful scrutiny, though continued for many consecutive minutes of each sitting at the microscope. This, however, must prove no discouragement, and should not damp the ardour of succeeding- observers, as in every branch or department of the science of the microscope, the most earnest, indefatigable, and tedious labours will often lead to disappointment and be unfruitful of results. It is only to those who hope against hope, who perseve re in the teeth of seemingly insuperable obstacles; in short, it is only to those who wait that success will eventually come, fully compensating for the labour spent, and replete with results of value and interest. I have treated this subject, with the substanti al whole before me, from the point of view of a micro-pathologist, although certain clinical facts, being inseparably connected with a thorough consideration of the disease, could not with propriety have been passed over, and this is the only apology I offer for their being joined in this place. I have refrained as far as possible from leading my readers into any unnecessary details of the case, and I trust also that there will be no more technicalities found here than the merest tyro in general pathology may understand.
POISONING BY ACONITUM NAPELLUS. BY CHARLES MORGJ\.N, M.R.C.V.S., NONINGTON, KENT.
ACONITUM NAPELLUS is cultivated in many gardens in this locality, being hardy and a handsome, free-growing flower.

The following case, which came under my immediate notice, I think worthy of note. Subject : a bay cob ; had been out several hours in perfect health, and was seen, while standing beside a fence, to bite off four pieces of the flower, which had just commenced blooming. The owner witnessed the occurrence, and could have taken the pieces out of the animal's mouth; but thinking there was no danger, allowed them to be masticated. He noticed, almost immediately, an increased flow of saliva. The horse went about a mile, and was then brought to my house and taken out of harness. I saw him in about two hours. The symptoms were frequent violent attempts at vomition, almost complete loss of power, reeling about and falling, pulse imperceptible, and purging commencing. Repeated doses of 01. Lini. were administered, with stimulants. The first dose stopped the efforts to vomit. Purging was very free for about twelve hours, when the patient gradually recovered, and in two days was well enough to walk home, a distance of four miles.

SINCE I introduced dialysed iron in combination with quinine, it has formed an important therapeutic agent in veterinary practice. Not being thoroughly understood what the chemical properties of dialysed iron is, this article is written as a supplement to my previous one, which has already appeared in the columns of this Journal. The substance, dialysed iron, or peroxy-chloride of iron, is prepared in the following manner:Dilute IO parts of solution of ferric chloride with cold distilled water, precipitate, it will dilute (riO) water of ammonia; wash the precipitate with cold water, and add it, while still moist, to I 1 parts of solution of ferric chloride contained in a sufficiently capacious flask. Put it aside one day, frequently agitating,
