15. _Worms in the Eye._--Several cases of worms in the eye are mentioned in the Bulletin des Sciences Medicales, for Feb. 1826. DEGUILLEME saw several in the eye of a cow; and the case was published by GORIER, a veterinary teacher, in his memoirs. In the report of the proceedings of the veterinary school at Lyons, in 1822-3, there is the case of a mule, in which a knot of worms (crinons) was seen in one eye. _Two_ were extracted; (why no more is not said;) and another subsequently. No inflammation was produced; but a violent nervous agitation of the head, and a turning of it to the left side took place. Next follows an account of a memoir read before the Medical Society of Calcutta, but of which the name of the author is not given. He is represented as stating, that the strongylus armatus minor of RUDOLPHI, and the _filiaris_ (filaria) papillosa, are frequently found in the eyes of the horses in India, but much more so in the cellular membrane, particularly about the loins. He believes that they make their way into the blood-vessels, and, through them, into the eye. Their most ordinary seat is the cellular membrane of the loins; where they exist for years, producing emaciation, and, at length, paralysis of the hind legs. This last the Calcutta author is represented as ascribing to the penetration of the spinal marrow; but he does not appear to have verified it by dissection. TREUTTLER says, he has seen the strongylus armatus in _aneurisms_ of the mesenteric artery of the horse; but the writer in the Bulletin doubts whether any have ever been found in sound arteries. Dr. KENNEDY, in the Edinburgh Philosophical Transactions, describes a worm, which he calls _ascaris pellucidus_, (pellucida,) as being common in the eyes of horses in India. A review of BREMSER'S work on worms is expected in our next, and inferences will then be drawn from these singular facts. 16. _Digestion._--MM. LEURET and LASSAIGNE, in their very interesting and valuable experimental essay on this subject, have met with many curious results. They found no remarkable difference in the saliva of carnivorous and herbivorous animals. The purest saliva was obtained for their experiments directly from the parotid duct, in man, the horse, and dog. The composition was as follows: Water, 99 parts; mucus, traces; albumen, soda, chloride of sodium, chloride of potassium, carbonate of lime, and phosphate of lime, 1 part. Total, 100. Their experiments on the bile confirmed the results of THENARD and CREVREUIL. The pancreatic juice is of the specific gravity 1.0026; at 15 deg. of the thermometer: (centigrade, we presume.) Its composition is: Water, 99.1 parts; animal matter soluble in alcohol, animal matter soluble in water, traces of albumen, mucus, soda, chloride of sodium, chloride of potassium, and phosphate of lime, 0.9 parts. Total, 100. This greatly confirms the analogy long observed between the pancreatic liquor and the saliva. In the _gastric liquor_, there are:
