For Inhalation only.
As all the Diseases mentioned in this Circular proceed from one cause, they can be Cured by
one remedy, viz., the CARBOLIC SMOKE BALL.
A NECESSITY IN THE NURSERY.
All who have the management and care of children know there is no more helpless being than a young child. It is powerless to help itself, and the most experienced mother or nurse is equally powerless to give the suffering infant the slightest relief. The CARBOLIC SMOKE BALL has been welcomed in the nursery of many homes for the relief it has given to infant sufferers from Croup, Whooping Cough and Colds. Not only is it now used to cure them, but also to ward them off, which it never fails to do.
To administer the CARBOLIC SMOKE BALL it is not even necessary to awaken the child, as the Powder emitted in front of the nostrils is inhaled unconsciously, and immediate relief is the result.
It is so harmless and easy to apply that an infant can take it with ease and safety. Nearly all diseases of children arise from one cold upon another, which, if not promptly relieved, usually lead to fatal results. Every nursery should have a Smoke Ball.
The CARBOLIC SMOKE BALL will not only cure all diseases caused by taking cold, but will, if used in time, positively ward of colds.
One CARBOLIC SMOKE BALL will last a family several months, making it the cheapest remedy in the world at the price -10s., post free.
The CARBOLIC SMOKE BALL can be refilled, when
diatoms and other minute algæ can be seen in various stages of digestion. The pseudopodia are excessively delicate, and require a nice adjustment both of focus and of the light, to clearly distinguish them. The artist has drawn the pseudopodia too dark. In all cases, the sarcode entirely fills up the delicate, membranous shell. The figures will show the general arrangement of the pseudopodia, which are almost constantly moving, though sluggishly, from side to side, or lengthening and shortening in the same slow, deliberate manner. A large nucleus is generally visible. My specimens were procured in great numbers, from the ooze of a clear pond. Although there was a constant though slow movement of the pseudopods, I never noticed any of the animals to move from
pole ; it is of various shades of brown, approaching to black. All my specimens were much more active than those of Pamphagus, among which they were numerous ; indeed, many of them would have been quite overlooked, had it not been for the bobbing about of the shell, as they were so very much like an aggregation of flocculent dirt. I think it very probable that the form is much more common than supposed, but that its inconspicuous character causes it to be overlooked ; or if seen, to be confounded with a minute Difflugia.

the position in which they were first seen under the microscope ; it is quite possible, however, that in summer they may show a greater activity in this respect. Like all other Rhizopods, they vary greatly in size, but the majority of my specimens averaged about the sto of an inch.

The agentes Pseudodiflugia differs from Pamphagus | St Cyphoderia ampulla is another Rhizopod, not un
only in the fact, that its chitinoid shell is incorporated or encrusted with sand-grains or dirt; in other words, it has the test of a Difflugia, but the delicate, filose, pseudopods of Pamphagus. There is only one species, P. gracilis, and in this the test is more or less void, with the mouth at the narrow
common in this district. I have found it in fair numbers in one clear pool, in several wells, and amongst Sphagnum ; from the latter, the specimens have been larger, and, I think, more active. The test of Cyphoderia is very elegant from its graceful curves, and its minute pitting in all its varieties. It is generally of a straw-colour or pale yellow, occasionally colourless and transparent, of chitinoid membrane. It is a long oval, or retort-shaped shell, with a cylindrical neck curving down to the mouth. The fundus, or top of the shell is either evenly rounded, or drawn out in the form of a nipple-like prolongation. When the pseudopodia are extended, and the animal is moving, the mouth is directed downwards, and the body of the shell is directed backwards and upwards, as in Fig. 205. Many of the shells exhibit minutely hexagonal markings arranged in spiral rows; others seem, even under high magnification, entirely destitute of this; while in others again, the markings are so coarse as to appear pitted. I have frequently dipped from my marine aquarium, a Rhizopod in every point like the one described, so I presume this species is both lacustrine and marine. The sarcode does not ordinarily fill the shell, though this is sometimes the case. There is a large clear nucleus, generally visible and one or more contracting vesicles. The pseudopodia are long and delicate, often radiating from the mouth, for a distance equal or even exceeding the length of the shell, in fine, thread-like branches. There is considerable variation both in form and size ; average specimens here are about ado of an inch in length, though I have seen others as small as the ad of an inch.

clutch of five. I give the measurement of the latter, as I have never known it equalled—it being quite the exception to meet with specimens fully an inch in length-1'0 by 65–10 by 65—98 by •62—98 by 65—92 by 65. The clutch of six-the only genuine clutch met with, which I have preserved-consists of exceedingly fine eggs, with the “odd egg” very pronounced. I must mention a clutch of five pygmean eggs, two being infertile. I think they would puzzle an old oological hand to recognize them. The eggs of this season were as a whole much more uniform in size than those of 1890. In that season many of the clutches contained a small but perfect egg, but this season this irregularity was quite exceptional. The smaller end marking only cropped up in one specimen, and that in the fourth clutch taken. I thought by its appearing so early in the season that more would be seen of it, but I have seen no further trace of it in any of the specimens brought under observation. There can be no doubt that the extreme rarity of these specimens is owing to the eggs being so large in proportion to the size of the birds.
Having examined such a large number of these eggs without meeting with anything like a double one, I began to think the sparrow to be quite exempt from this phenomenon ; however I am able to say it is not the case, and I now place on record—I believe for the first time—that an egg has been found containing two chicks. The egg in question was one of a clutch of five, very ordinary-looking, and very uneven in size, so much so that had I not known them to be a genuine clutch, I should have placed them on one side. This egg having somewhat the appearance of a double one, by its being so much broader than the others at the smaller end, made me examine it carefully. This I did by dividing the shell, and found an embryo in each end. These I removed, and by a little manipulation I placed the pieces of shell together, which show a very good specimen of a double egg, which I believe to be unique.
As this investigation was going on I occasionally met with an egg in which the embryo was dead, whilst the other eggs of the clutch contained healthy chicks. I knew it to be impossible for eggs to get chilled in such a warm nest as the sparrows generally build, but I thought it quite possible that their sharp claws might puncture the delicate shells. This I found to be the case. Having no wish to give the impression that I am shooting at these birds “ with a long bow," I have preserved some specimens to corroborate the fact. It is curious that such a slight injury should destroy the embryo in nearly any stage of incubation, and also curious that these birds-considering the number of enemies they have-should assist in destroying their own eggs, from what may be called, hygienic neglect.
At the commencement of the season I expected it would prove a worse one than any I have recorded,

say after reading this paper, “What is the use of bothering about the sparrows ? Kill them all !” Others will say “Very disgraceful taking sixty clutches of their eggs !” I
say that sixty clutches are but a very small portion of those annually destroyed in this locality by those who consider them a pest. I have now for the sixth season paid considerable attention to their nidification and added another sixty clutches to my collection. They have not been collected, examined and prepared without considerable trouble, for which I have been duly rewarded by their revealing some facts which I believe have not been previously recorded.
They began nesting about the usual time, but in one locality they were quite ten days earlier than in another three miles distant.
