Doctor Solly has an extensive practice in Colorado Springs and the neighbourhood, and is reputed to be, I should think justly, the first medical man there. What he says, therefore, on the advantages of the Sanitarium deserves every attention, the more so that he honestly points out, in more than one place, the individual conditions which are more likely to receive harm than good from a residence on such high, dry table-land. I will now proceed to make extracts from the combined book of Mrs. Dunbar and Doctor Solly, and as, in a medical point of view, it explains much, I will first set out the preface to Doctor Solly's work _in extenso_. "A committee appointed by our citizens having requested the County Medical Society to select one of their number to write an article, for general publication, upon the qualities of this locality as a health-resort, the choice fell upon me, and the following pages have been written to comply with this request. The opinions therein expressed are set forth upon my individual responsibility, and not as being the combined outcome of the views of the County Society at large. I am, however, indebted to my colleagues for several valuable suggestions and points of experience, but with respect to a subject so complicated as Climatic Influences the saw applies '_Tot homines, tot sententiæ._' Nine years ago I resigned the practice of medicine in England to try the influence of the Colorado climate upon my health, with satisfactory results, and the opinions and statements here advanced are founded upon my experience and observation as a practitioner of medicine in this locality for the last nine years. The article being limited did not permit the publication of clinical records or extended discussion of the many interesting problems referred to, but is put forward as an effort to assist physicians and their patients in answering the often recurring question of the wisdom of a change to Colorado, from some safe standpoint and not merely from hearsay reports unsupported by evidence or reasonable inference. Viewing this subject of Climate as resting upon a scientific basis, and not alone upon empirical knowledge gained in particular regions, I have followed the plan of first stating the facts and opinions that are generally known or accepted concerning the features and essentials of climates in general, and their influence upon the healthy body; secondly, giving the general features of elevated climates and their effects both in health and disease, and finally, comparing these general effects with the special effects observed in this particular locality. Thus I have endeavoured to show good reason for the faith that is in me, by connecting this fragmentary study of climate with the whole great subject of climatology." "S. EDWIN SOLLY." "Colorado Springs, 1883." Colorado Springs is thus described by Mrs. Dunbar.
