Brace that it is becoming quite a common practice in the United States to remove some of the molar teeth of children, as the jaw does not grow large enough for the perfect development of the normal number. Prof. With respect to the alimentary canal, I have met with an account of only a single rudiment, namely the vermiform appendage of the caecum.

But to return to matters of importance, I should be very happy to see the proofs of your paper upon the vermiform appendix. I may be able to furnish you with material for a footnote or two." "Your assistance will be invaluable to me," said O'Brien, with enthusiasm, and the two men parted in the hall.
At the postmortem" here the doctor paused in his walk, lowering his voice almost to a whisper while he bent over the boy "at the post-mortem the knife discovered an abscess on the vermiform appendix. The discovery was made too late." These were the days before appendicitis became fashionable.
This, then, was why he had let himself down so unexpectedly; and we noticed that the instant he touched the ground, he rolled himself into a round clew, presenting on all sides the formidable chevaux-de-frise of his quills. "The marten now ran around him, doubling his long vermiform body with great activity at intervals showing his teeth, erecting his back, and snarling like a cat.
The larvae of most insects pass through a worm-like stage, whether they are active and adapted to diversified habits, or are inactive from being placed in the midst of proper nutriment, or from being fed by their parents; but in some few cases, as in that of Aphis, if we look to the admirable drawings of the development of this insect, by Professor Huxley, we see hardly any trace of the vermiform stage.
This latter fact was sometimes made evident, when a worm had subsequently bored through a flat circular disc of this kind, and heaped up a fresh vermiform mass in the centre. These flat subsided discs have been repeatedly seen by me after heavy rain, in many places on land of all kinds. On the flowing of wet castings, and the rolling of dry disintegrated castings down inclined surfaces.
If a Bipinnaria, a Brachiolaria, a Pluteus, is competent to produce the Echinoderm, which is so widely different from it; if a hydroid polype can produce the higher Medusa; if the vermiform Trematode 'nurse' can develop within itself the very unlike Cercaria, it will not appear impossible that the egg, or ciliated embryo, of a sponge, for once, under special conditions, might become a hydroid polype, or the embryo of a Medusa, an Echinoderm."
The vermiform larvae of moths, flies, beetles, etc., resemble each other much more closely than do the mature insects; but in the case of larvae, the embryos are active, and have been adapted for special lines of life.
It is true that the Amphibia have two lungs, right and left. Ventral and pectoral walls are removed. The greater part of the body-cavity is taken up with the liver, from the middle part of which the caecum and the vermiform appendix protrude. Immediately behind the single structure of the thyroid gland a median groove, the rudiment of the trachea, is detached from the gullet.
