52 THE MICROSCOPICAL NEWS. 
article alone gives but a poor idea of the whole work, as the 
original is illustrated with an excellent chromo-lithograph and a 
perfect slide, to illustrate the subject. 
Co.e’s Stup1Es.—Numbers 7 and 8 of Volume II. are before 
us ; the former contains an account of epithelial tissue, simple, 
stratified and transitional, the simple being tabulated as pavement, 
columnar, glandular and ciliated. A coloured plate illustrates the 
slide accompanying the number, demonstrating the structure of 
epithelium from the tongue, intestine, and fauces. 
No. 8 treats of the cell as an individual, and is described and 
illustrated by a beautiful plate of the desmid J@icrastertas dentt- 
culata. ; 
No. III. of the Popular Microscopical Studies with its accom- 
panying slide is devoted to the Hair follicles, glands and tissues of 
the Human scalp. The fifth part of ‘“‘The Methods of Micros- 
copical Research,” is a continuation of the preparation of tissues. 
STAINING AND MountTiINc PoLLen.—The following appeared in - 
the American Monthly Microscopical Journal for 1880, as the 
process of preparation adopted by the Rev. J. S. Brownell, who 
exhibited, at a meeting of the New York Microscopical Society, 
some slides of stained Pollen of special excellence. 
“« A small quantity of Pollen having been placed on the centre 
of the slide,.a small drop of staining fluid (anilin dissolved in 
alcohol), is placed upon it. Then wash by dropping on pure 
alcohol until all traces of sediment or of stains upon the glass 
among the Pollen grains are washed away. Wipe clean with a dry 
cloth drawn over the end of a pointed stick, turning the slide 
rapidly on the turn-table. When thus cleaned and quite dry, put 
on a drop of spirit of turpentine, and then the balsam and cover.” 
“ A few kinds of Pollen are distorted by the action of alcohol. 
Some of these can be stained by the use of an ammoniated solution 
of anilin. Those that will not bear this solution may be mounted 
unstained.” 
PHOTOMICROGRAPHY.—I have often thoughtif Microscopists knew 
how easy it was to adapt an ordinary photographic camera for Micro- 
scopical work they would employ photography much more than they 
do at present. For any one intending to read a paper before any 
scientific society it is very useful to have it illustrated in some 
way, and asarule Microscopists are not good at drawing, and 
further find the camera lucida a tedious and not very satisfactory 
process. No doubt many have thought photography would be a 
very convenient way, but that it would entail a special camera. 
Such however is not necessarily the case, and using an ordinary 
camera has the double advantage that it can be used for ordinary 
photography when not required for the microscope. The difficulty
