456 POPULAR SCIENCE MONTHLY. 



mon Plants, by Dr. Goodale; and Commercial and Other Sponges, 

 by Professor Hyatt and others— were pnblished by Messrs. Ginn 

 and Heath, who have since bronght ont many snch helps. 



After a winter of intense activity there came a period of repose, 

 and no lectnres were given the next season. After lying qniet for 

 a year the school once more came into active operation. Mrs. 

 Qnincy A. Shaw and Mrs. Augustus Hemmenway showed their 

 sympathy with the efforts on behalf of education by most generously 

 assuming the whole expense of the lessons given that year. Imme- 

 diate measures were taken to carry ont the ])lan which had been 

 arranged several years before, which consisted in giving a series 

 of lessons which would be a good preparation for a course in physi- 

 ography. Accordingly, Professor Cross, of the Institute of Tech- 

 nology, was engaged to give eight lessons in physics. Professor Hyatt 

 following with eight on the physical relations of animals to the 

 earth; Professor Goodale gave four treating of plants in the same 

 way, and Mr. W. O. Crosby concluded the course with four lectures 

 on the relations of geological agencies to physiography. The ap- 

 plications for tickets to these lectures so far exceeded the expecta- 

 tions of the committee that they were forced to duplicate them, 

 each speaker repeating his lesson on the same day before a differ- 

 ent audience. 



After this the work of The Teachers' School of Science was 

 taken under the protection of the Lowell Fund, Mr. Augustus 

 Lowell sending word that he would make an annual donation of 

 fifteen hundred dollars. ^Ir. Lowell allowed the Natural History 

 Society to make engagements and announce lectures one year be- 

 forehand, and also gave the use of Ilnntington Hall. Eighteen 

 lectures were given that winter, undcn- the title of the Lowell Free 

 I^ectures in The Teachers' School of Science. Eight of these lec- 

 tures Avere on physics, by Professor Cross; five on geology, by Mr. 

 Crosby; five on physiology, by Dr. H. P. P)0\vflitch, of the Har- 

 vard Medical School, and all were very successful and well attended 

 l>y the teachers. The Teachers' ScIhm.I of Science had another 

 hi-anch in active operation, which was courses of laboratory lessons 

 paid for by the teachers themselves. 



Through tlu^ liberality and co-operation of the AVoman's Edu- 

 cation Association the Society of Natural History was able to an- 

 nounce that a seaside laboratory, under the direction of Professor 

 Hyatt and cajiable of accdmniodating a liiuitcMl number of students, 

 would be open at Annisqnam, ]\Iassacliusctts, from June Sth to Sep- 

 tember 1 5th inclusive. The ]>ur])osc of this laboratory was to afford 

 opportunities for study and (.l)S('i'\ati(in to the development, anat- 

 omy, and liabits of coumion ty])es of nuu-ine animals under suitable
