370 CHAPTER XXX. 



GRAND-MOURSEL and THIBONDEAU (C. R. Soc. Biol., liii, 

 1901, p. 187) recommend for pancreas NICOLLE'S " thionine 

 pheniquee," which stains the ins ill tv) of Langerhans hardly at 

 all, the rest strongly. 



730. Gastric Glands. KOLSTER, (Zeit. iviss. Mik., xii, 1895 

 p. 314) differentiates the two kinds of cells in stomach 

 glands by over-staining with hasmatoxylin, washing out with 

 alcohol containing 1 per cent, of HC1, blueing with alcohol 

 containing 1 per cent, of ammonia, and, after washing, 

 staining for one to five minutes in a weak solution of 

 Saurefuchsin. Peptic cells blue, parietal cells red. Osmic 

 material cannot be employed. 



CADE (Arch. Anat. Micr., iv, 1901, p. 4) stains material 

 fixed with Bourn's picroformol in Victoria blue of 1 per cent. 



R. and L. MONTI (Rich. Lab. Anat. Roma, ix, 1902) demon- 

 strate ducts and canaliculi of delomorphous cells by Golgi's 

 bichromate and silver impregnation, especially with reju- 

 venated material (see SACEUDOTTI), leaving it for 5 or 6 days 

 in half-saturated sulphate of copper, then for 24 hours in the 

 osmic-bichromate mixture. You can imbed in paraffin 

 (rapidly). . . . 







731. Intestine. BEKSLEY (Amer. Journ. Anat.., v, 1906 p. 

 323) stains sections of glands of Lieberkiihn in a mixture 

 of equal parts of saturated solutions of Orange G and 

 Saurerubin, and then with toluidin blue, and mounts in 

 balsam. 



732. Liver. BRAUS (Denhschr. Med. Nat. Ge#. Jena, v, 

 1896. p. 307) demonstrates the bile capillaries by the rapid 

 method of GOLGI, hardening in a mixture of one part formol 

 with three parts liquid of M tiller or ^ per cent, chromic 

 acid. 



EPPINGER (Beitr. path. Anat., xxxi, 1902, p. 230) studies 

 them by means of a complicated modification of WEIGEKT'S 

 neuroglia stain, and CIECHANOWSKI (Anat. Anz., xxi, 1902, p. 

 426) by means of WEIGERT'S myelin stain (the 1885 method). 



OPEL (Anat. Anz., v, 18DO, p. 144; vi, 1891, p. 168) puts 

 pieces of liver or spleen (alcohol material) for twenty-four 

 hours into a solution of neutral chromate of potash (4 to
