    minerals, rocks, and chemical substances, elemen- tary and otherwise, are found in Nature in such minute particles as to render them suitable for immediate examination and study under the microscope, but, in the majority of instances, it is necessary either to pulverise, grind them down into the thinnest possible sections or sheets, or to precipitate them by chemical means ere they can be brought within the range of observation, and thus the petrologist must be provided with chisels, hammers, files and stones for grinding and polish- ing, and a variety of instruments adapted to the collection and subsequent treatment of specimens, whilst the chemist will require blow-pipes, test tubes, re-agents and balances, &c., &c. For investigations in the organic world, the vegetable histologist must provide himself with a vasculum, a trowel, dipping bottles, and all necessary col- lecting apparatus of all kinds, and with all the various instruments necessary to facilitate the examination of the unicellular and more delicate forms of plant life, whilst the more highly organised and complex examples will require dissection or sectionising and, in many cases, chemical treatment before they can be examined to any useful purpose. The animal histologist again will find his work inextricably connected with that of his brother botanist, and, to a large extent, will work hand in hand with him, but, as his observations and inquiries progress, there will arise necessities for a collection of tools including scalpels, scissors, bone forceps and saws, needles, forceps of different sizes and forms, section knives, as well as the all-impor- tant and indispensable microtome; whilst both
