That the public and private schools are finding the exhibits in 

 the Museum interesting and helpful in their educational work 

 is evidenced by the large number of schools that, with their 

 teachers, visit the Museum each year. During 1919 there 

 were schools from San Francisco, Berkeley, Oakland, Alameda, 

 Piedmont, San Jose, and San Anselmo, 



Whenever opportunity ofifered it has been the policy of the 

 Director to accompany the schools through the Museum, ex- 

 plaining briefly the general features of installation and calling 

 attention to the educational value of certain exhibits, and then 

 taking the schools into the lecture hall and showing them 

 stereopticon slides and moving pictures of the species of ani- 

 mals shown in one of the groups. 



The visits by schools in the year have been as follows : 



Number of schools represented 80 



Number of classes or grades 214 



Number of teachers in charge 215 



Total number of pupils 7000 



LECTURES 



The practice of maintaining courses of free lectures on popu- 

 lar scientific subjects has been continued. These have been, as 

 heretofore, in two series — first, those given at the regular 

 stated meetings of the Academy in the hall of the Engineers' 

 Club of San Francisco, 57 Post Street, on the third Wednes- 

 day evening of each month (changed September, 1919, to the 

 first Wednesday of each month), and, second, those given at 

 three o'clock each Sunday afternoon in the Auditorium of the 

 Museum. These lectures have without exception been well 

 attended, the audiences at the Sunday lectures usually equalling 

 or exceeding the seating capacity of the hall. 



A list of the lectures given in 1919 will be found in the Presi- 

 dent's report (pp. 359-361).
