APPENDIX
A CATALOGUE OF SPECIMENS OF ROCKS AND MINERALSILLUSTRATING THE REPORT OF A GEOLOGICALSURVEY OF MASSACHUSETTS .
Collected by Order of the Government of the State .
The State Collection contains two sets of specimens, both numbered from unity onward. Thesmallest set consists chiefly of soils, clays, and marls ; and all the specimens are contained inglass bottles, ticketed and sealed, and extending to 227. In the other set, which contains 2646specimens, the numbers are usually attached directly to the specimens, though some of them arein bottles. When reference is made to this Collection in the preceeding Report, the letter b, isannexed to the specimen belonging to the first or smallest set, except the soils proper, whichamount to 152: and which can hardly be confounded with the specimens of the other set. Inthe second set considerable irregularity will be perceived in the order of the numbers, occasionedby the re-survey, which made it necessary to add a second set of numbers to the first, under thedifferent rocks. This could not be avoided without numbering over the whole Collection anew.
About 130 of the specimens have been smoothed or polished ; and this is mentioned undereach number, where such is the case. Those specimens that have been only smoothed, havebeen varnished ; and this process will need to be renewed occasionally. I found that in this waythe true character of the rock could be brought to light quite as distinctly as by polishing ; andthus the expense was considerably reduced.
