washed out with strong alcohol, dehydrated, and imbedded 

 in paraffin and sectioned. The sections are stained on the 

 slide in the mixture quoted 252, as there described.

703. Nervous Networks of the Liver (IGACUSCHI, Arch. f. path. 

 Anat., xcvii, p. 142 ; Zeit.f. wiss. Mik., 1885, p. 243). For the demonstra- 

 tion of those particular networks that are found in the liver, and that have 

 been interpreted as nervous networks by some observers, as elastic tissue by 

 others, Igacuschi proceeds as follows : Pieces of liver (either fresh, or 

 hardened for some days in solution of Muller) are put for eight or twelve 

 hours into a solution composed of 100 parts of water, 20 parts of grape sugar, 

 and 1 part of common salt. They are then put into 0'5 per cent, solution of 

 gold chloride, and after twelve to twenty-four hours therein are put back 

 again into the grape sugar, where they remain for two or three hours at 

 the temperature of an incubator, or, which is better, twelve to forty-eight 

 hours at the normal temperature. Sections are then made by the freezing 

 method, and mounted in salt solution or glycerin ; or by the collodion 

 method and studied in clove oil. 



704. Other Glandular Structures. See, amongst other impor- 

 tant papers that want of space precludes me from noticing 

 here, RANVIEK, Les membranes muqueuses et le syst. gland. 

 (Journ. de. Microg., ix, x, 1885 1886) (principally concerned 

 with the investigation of the liver), and the same author's Le 

 mecanisme. de la secretion, ibid.,Xj 1886 1887, which contains 

 a variety of observations on other glandular structures.
