During the second term instruction was given to Natural 

 History 7 in Professor Farlow's own working-room at the 

 Museum. This was necessary in consequence of lack of facili- 

 ties for illustrating the study of cryptogams at the Botanic 

 Garden. Hereafter, however, this class will be furnished with 

 a room in Harvard Hall, thus leaving Professor Farlow's room 

 free for the arrangement of collections, and such work as may 

 be done by persons doing special work in cryptogamic botany. 



During the academic year 1883-84 the general lectures in 

 Zoology by Dr. Mark were given for the first time in the new 

 lecture-room at the Museum, which affords ample accommoda- 

 tion for even larger classes than those of the past few years. 

 The course was attended by one hundred and eleven students, 

 of whom one hundred "and four were in attendance during the 

 whole year, and seven for somewhat more than half the year. 

 Of those who completed the course twenty-three were Seniors, 

 thirty-four Juniors, thirty-eight Sophomores, one Freshman, 

 four special students, and four Scientific School students. 



Professor Mark has given assistance during the year to two 

 students engaged in special zoological investigations. The 

 work of one of them, an undergraduate, is not yet completed. 

 The other person, to whom the privileges of the Museum were 

 extended by the Curator, has produced a paper which is now in 

 press, and will soon appear in the Proceedings of the American 

 Academy : " On the Anatomy and Histology of Aulophorus 

 vagus. By J. E. Reighard." 



The new Zoological Laboratory affords excellent facilities for 

 the prosecution of the more delicate histological and embryologi- 

 cal studies, and has been found by a year's trial to meet every 

 essential requirement of such a work-room. 



The paper previously reported as prepared last year, by 

 William Patten, has recently been published with some addi- 

 tions, in the Quarterly Journal of Microscopical Science, Lon- 

 don, Vol. XXIV., 1884.
