mimeographed and given to the students at each succeeding 
Clinic. This procedure has proved more valuable than when 
students themselves made notes. It has also enabled me to keep 
a record of the subjects presented, has avoided repetition and 
furnished a definite material from which examination questions 
might be selected. 
Frequently, students and visiting physicians have suggested 
that the Clinics and Lectures be issued in consecutive order and 
in form more substantial than loose mimeographed sheets. Dif- 
ficulties attendant upon such arrangement finally have been 
overcome and this volume contains the bulk of the clinical 
matter presented during the past three months. It is hoped 
that each quarter similar collections of Clinics and Lectures 
may be issued and 'that the venture may prove as useful to 
medical men, generally, as it has proved already to a limited 
group of students.

FROM THE PREFACE 
The efficacy of ultra violet rays in the practice of dermatology 
is now thoroughly established, and its bactericidal action, its 
anti-pruritic and analgesic effects, as well as its reconstructive 
action upon epidermal cells and its constitutional effect upon 
the general economy, cannot now be denied. 
The author has been prompted to write this book because no 
American author has heretofore attempted it, the profession 
relying entirely upon the writings of their European colleagues. 
It is the author’s intention to present the subject as briefly 
as possible with clearness, and with no intention of going into 
histo-pathologic details. The mere thought in mind will be to 
give in a practical way to the profession the results of his 
clinical experience with the use of ultra violet radiations in 
the treatment of the various skin diseases for which he has 
found the ultra violet light a desirable agent. 
The author has thoroughly gleaned the literature of the day 
and hereby gives credit for the material which he has used 
therefrom to the foreign writings of Morris, Dore, Bach, Wag- 
ner, Kruger, and Blaschko, and to the following writers from 
our own continent: Martin, MacKee, Jordan, Plank, Collins, 
and Allen.
