The Class in Mineralogy.
None of the courses of study we have ever had the pleasure of offering to our friends, has had the magnificent success which is attending Prof. Crosby's class in mineralogy. At this writing no less than eighty-nine pupils are enrolled, and as Chapters usually take the course through one representative, this number doubtless means that at the least five hundred persons are learning how to observe and describe minerals, under most competent instruction. To each pupil is sent a set of thirty valuable specimens, and all exercises are corrected and returned for revision. Geographically, the class extends from Washington Territory to England.
