found in books of reference. Some of the 

 words proposed by the author are not ac- 

 cepted by good autliorities, as for example, 

 ' chemic ' for chemical, ' physiologic ' for 

 phj'siological, and in this respect the work 

 is sometimes misleading. In the attempt 

 to give a complete list of the bacteria many 

 names are given which would not be ac- 

 cept<?d l)y a bacteriologist, the list evidently 

 having been prepared by some one not 

 familiar with the subject. These, however, 

 are minor details ; the main fact about the 

 work is that it is the most complete and 

 practically useful single volume dictionarj- 

 of medical terms in the English language, 

 and as such it is commended to the readers 

 of Science. 



NOTES. 

 THE INTEENATIOXAL ZOOLOGICAL CONGREaS. 



The following invitation has just been 

 issued to the Third International Zoological 

 Congress to be held in Leyden next Septem- 

 ber : " The first International Zoological 

 Congress took place in Paris at the time of 

 the International Exhibition of 1889. The 

 second meeting was held in Moscow in 1892. 

 There the resolution was passed that in 

 September, 189.5, this Congress would again 

 meet in Leyden, the oldest University of 

 the Netherlands. The Netherlands' Zoolo- 

 gical Society has taken upon itself to make 

 all the necessary arrangements for the re- 

 ception and accommodation of the Congi'ess. 

 At tlie invitation of that Society, the under- 

 signed request you to become a member of 

 the International Congi-ess and to attend 

 the Leyden meeting. It ajipears probable 

 that diil'erent questions, in which the inter- 

 est of zoologists in general, as well as those 

 of specialists are involved, can be brought 

 to a solution by mutual exchange of opinions 

 on the occasion of such an international 

 meeting. At any rate the way that will 

 lead to such a solution may there be pre- 

 pared. Moreover it is undoubtedly a dis- 



tinct advantage to become personally ac- 

 quainted with representatives of Zoological 

 Science from diU'erent parts of the world. 

 As soon as you shall have expressed your 

 sj-mpathy with tlie above stated aims of the 

 International Zoological Congress we shall 

 be glad to be allowed to append your name 

 to a more general invitation directed to all 

 zoologists and morphologists, which will be 

 brought before our fellow-workers by the aid 

 of diflerent periodicals. We venture to 

 add that even in case of your not being able 

 to attend the proposed Congress you will 

 favor us with the expression of your sym- 

 pathy with the movement. Pray to be 

 so kind to send your answer to Dr. P. P. C. 

 Hoek, Secretary of the Netherlands Zoolo- 

 gical Society at Helder, Holland." 



The invitation is signed by about one 

 hundred naturalists in different jiartsofthe 

 world, including the following from tliis 

 country : A. Agassiz, E. D. Cope, E. L. 

 Mark, O. C. Marsh, H. F. Osborn, W. B. 

 Scott and C. O. Whitman. 



THE TESTING OF ELECTRICAL STREET 

 RAILWAYS. 



The expenditure and distribution of 

 power on electrical street railwaj-s has 

 formed a subject of investigation on a some- 

 what extensive scale, and for a number of 

 years past, by the departments of Sibley 

 College, Cornell Universitj'. In the issue of 

 the Sibley College Journal for January, Mr. 

 James Lyman, formerly of Yale University, 

 now engaged in special work of this char- 

 acter in the graduate department of the 

 College, summarizes some of the most im- 

 portant results thus collated. In the per- 

 formance of the work of investigation, par- 

 ties are sent out, sometimes to the number 

 of ten or a dozen, including the experts in 

 charge and their student-assistants, di- 

 vided into squads, assigned each to its spe- 

 cial part of the work, the electricians to the 

 measurement of current, the electrical en-
