NOTES AND QUERIES. 209 
hired of Messrs. Ross and Marshall, of Greenock, for a week, com- 
mencing Monday, 2nd July; facilities will thus be afforded for 
dredging excursions, not only in the districts previously worked, but 
also in distant localities. , 
The time for the excursion will be from the 29th June to the 
roth July inclusive, but members may return at any time during 
the month. The arrangements for the return journey on roth July 
will be similar to those for the outward journey ; but members may, 
if they prefer it, return by rail vza Glasgow. 
It is estimated that the expense will be a little over £13 13s. for 
the twelve days. 
THE MetuHops or MicroscopicaL REsEARCcH.—The first part 
of this work by John Ernest Ady was issued to subscribers on 
June 16th, and is but an introduction to that which is to follow. 
The work promises to be exceedingly interesting. 
Microsia OF MarINE FisH.—At the zoological station recently 
established at Havre, L. Oliver and C. Richet have carried on an 
extensive series of experiments on the presence of microbia in the 
tissues of living fish. With one or two exceptions, they find these 
organisms universally present in the peritoneal fluid, the lymph, the 
blood, and, in consequence, in the tissues. They have all the 
characters of terrestrial microbia, and are reproduced in the same 
way, by division and by spores. ‘They are most numerous in the 
peritoneal fluid, less so in the blood and lymph. 
The most common form is that of bacilli, longer or shorter, en- 
dowed with oscillatory movements; they are coloured by ammonium 
picrocarbonate and by aniline pigments ; some are provided with 
spores, either in the middle or at the extremity of the rod.—See 
J. R.M_S., June, 1883. 
ANILIN CoLouRING MaTTers AS STAINING MEDIA FOR HUMAN 
AND ANIMAL TissuEsS.—Dr. H. Griesbach discusses the value of 
anilin colours as staining media for human and animal tissues, and 
gives the results of his own experience. His paper is not capable 
of useful abstraction, being already in a condensed form, but the 
following brief account is given to call attention to its existence 
and to enable reference to be made to the original. 
Anilin-yellow he considers unsuitable. Sdwre-gelb, colours bone 
a beautiful orange, tracheal cartilage and connective tissue lemon. 
In sections of the intestinal sac of Uzzo the epithelium is orange, 
muscle gold, glandular tissue brownish, and the nuclei of the cells 
are very clearly shown. Nerve-elements are not so well coloured, 
nor any isolated cells except gland-cells. It does not appear to be 
suitable for chromic acid preparations. Czrysotdin is useful for 
bone and all kinds of connective tissue, which it colours a bright 
yellow. Its best effect is with fresh preparations. zsmarck brown
