TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 51 



in man twice in the liver (in one 

 case over two quarts and one 

 quart in the other case) ; between 

 the extensors of the thigh ; one in 

 the bulbus of an eye extirpated 

 for panoohthalmitis ; once it 

 passed from the bowels of a lady 

 who had often suffered from pain 

 in the liver, but did not show any 

 tumor. My soil took a great many 

 €chinococcas from the bladder of 

 a child; they were large, traiis- 

 parent anvd elongated. All these 

 specimens I mentioned contained 

 booklets, and so the diagnosis was 

 correct. I understand that Dr. 

 McLaughliii, in Austin, also re- 

 moved echinoeocci from the vagi- 

 no-rectal cellular tissue. I am sure 

 if proper inquiries were made it 

 would prove to be so. The st>eei- 

 mens of which you send the photo- 

 graph is a true echinoeoceus, as 

 the multiplicity of the heads in- 

 dicate. ' ' 



Besides above, I have a few 

 other cummunieations on cases of 

 echinoeocci in man, including one 

 of Dr. R. H. L. Bibb, of Saltillo, 

 Mexico, stating that he had re- 

 moved a cystic tumor several 

 years ago, situated in the cellular 

 tissue between the "trapezius" 

 and the "latissimus dorsi" mus- 

 cles, which the microscope showed 

 to be due to this parasite. 



The microscopic mountings 

 which I prepared from specimens 

 of diseased rablaits, I may state, 



were examined by frifends with 

 much interest; especially also in 

 the private bacteriological labora- 

 tory of Dr. Julius Braunnagel. . 



After above had been written, 

 an additional paper on the sub- 

 ject heading this article was con- 

 tributed to the Texas Medical 

 Journal, and I herewith submit the 

 main part of same: 



These investigations will show 

 that after the development of the 

 premature or embryonic psrasite 

 jof ihe echindcoccus tapeworm 

 from the ingested ova of the ma- 

 ture taenia, up to the migration, 

 encystment, and STirouting of new 

 embryonic colonies inside the 

 cyst membrane in different parts 

 or organs of the human, and ani- 

 mal system, that all of these par- 

 asites in their most primitive sta- 

 dia already show quite a well- 

 developed head with characteristic 

 suckers and booklets and" after 

 further development, free them- 

 selves from the endocystic mem- 

 brane, although still adherent to 

 its linings and ultimately, after 

 still further development, some of 

 the more mature of these embry- 

 onic parasites isolate themselves 

 later and free themselves entirely 

 from the other more premature 

 crop, and can then be found in a 

 free state either near the base of 

 the endocystic membrane or in- 

 side of the cyst fluid. 



Something About the Texas Prairie Spider. 



In his ramblings about the 

 prairie-plains, river-bottoms and 

 forests, the hunter and lover of 

 nature encounters a large variety 

 of interesting arachnids, from the 

 smallest, hardly visible spinning- 

 variety up to the haud-large black 

 or brown-colored and fearful look- 

 ing .jumping tarantula. 



With its inimense area of over 

 274,000 square miles and sunny 

 clime, Texas naturally harbors a 

 large variety of spiders .of differ- 



ent type and colors; and, al- 

 though the more dangerous types 

 are not as numerous as encoun- 

 tered in the tropical zones of oth- 

 er countries, we have among the 

 smaller variety of interesting 

 arachnids some very vicious speci- 

 mens; and among these the small 

 speckled vagabond' or jumping 

 tarantula is most conspicuous. 



For reason of a lecture before 

 the San Antonio Scientific So- 

 ciety, the writer had the pleasure
