To the Editors of the CRIMSON:

As there are at present several cases of measles and mumps among Harvard students, I desire to call attention to the importance of consulting a physician immediately if there is the slightest occasion to suspect either disease. I should also like to emphasize the following facts:

1. Although in measles the rash is usually preceded, for three or four days by fever, malaise, and symptoms of a "cold in the head," Frequently the first thing that leads the student to consult a physician is the appearance of a spotted eruption on the face, cheet and abdomen.

2. Measles is a highly contagious disease and as much so before the appearance of the eruption as afterwards.

3. Usually the first thing noted in mumps is the swelling of the parotid gland, which lies in front of, and beneath, the lower lobe of the ear.

4. It is quite possible for the same individual to have either measles or mumps two or more times.

This letter is prompted by the fact that several men have recently gone about as usual for one or more days after these contagious diseases might have recognized had they consulted a physician. M. H. BAILEY.
