184 EXTRACTS AND ABSTRACTS FROM FOREIGN JOURNALS. 



viewed laterally, appeared as if placed in the posterior portion of the 

 body; and here also might be seen sometimes two or more vesicular 

 bodies. In the dying or dead animal, a sinuous tube, having an enlarged 

 extremity, was to be observed, which was probably an intestinal canal. 

 In the interior of the body was an apparatus of cilia, though it was not 

 always very distinctly seen. The internal large bladder was sometimes 

 so much distended, that it covered a great portion of the other organs. 

 Besides these, numerous small granules, varying from each other very 

 much in size, were seen internally. Remarkably enough, the neigh- 

 bouring intestine of the frog, did not contain any of these animals, but 

 an immense number of Infusorial creatures, and a Filaria. A single 

 specimen was found near the liver. 



Negrier on the connection of Menstruation with the Graafian Vesicle. 

 Menstruation, according to the author, is connected with a periodical 

 bursting of a Graafian vesicle in the ovarium. In the new-born female 

 there are only to be found rudiments of follicles ; about the 12th year, 

 a grey matter is observed within the follical coverings, which soon be- 

 comes hardened. At puberty the interior of the follicle becomes yellow, 

 and the follicle itself is now more vascular. At the first menstrual pe- 

 riod, a follicle swells, and bursts at its peritoneal surface. This is re- 

 peated at each menstruation, and ceases at the time when the uterine 

 discharge stops. 



Grube on the Menstrual Blood. Besides want of coagulating power, 

 and the presence of much albumen, with diminished quantity of fibrine, 

 the menstrual blood is characterised by the altered condition of the true 

 blood- globules, which are often notched and crumbled. 



Storer and Valentin on the Spawn of Syngnathus. Storer has observed 

 abundance of spawn in the male Syngnathus, which decidedly receives 

 the eggs from the female. Valentin remarks since the confirmation of 

 the opinion of Rathke, that the female bears the spawn, I have several 

 times examined, under the microscope, the organs, or at any rate 

 what was analogous to them, mentioned by Rathke, taken from spe- 

 cimens preserved in spirits, belonging to the species S. pelagius, Op- 

 hidion, and Rondeletii, and have seen the elements of the egg in the 

 generative organs. On the other hand, in a fresh Syngnathus, provided 

 with spawn, which was obtained at Nizza, the genitals appeared per- 

 fectly white, and only exhibited, under the microscope, granular bodies, 

 so that even after a microscopical examination, I could not say to which 

 gender the creature belonged. 



Langenbeck on Medullary Sarcoma. The femoral artery of a dog was 

 opened, and some blood drawn off ; this being freed from its fibrine, was 

 mixed with the soft matter of a medullary sarcomatous tumour of the 

 humerus, and injected into the artery ; the diseased limb had been 

 amputated two hours and a half previously, and was not quite cold. In 

 nine weeks time there were found two or three light-blue circular and
