jects, and they are works which will be of importance as standard 

 books for a long time. They certainly do not give an explan- 

 ation of the origin and nature of the disease; the time had not yet 

 come for that ; neither do they give a certain and formulated mode 

 of cure, if there is to be such a thing : but in these books he describes 

 and defmes the symptoms of this terrible disease, the ways in 

 which it shows itself, and the dilference between real leprosy, in its 

 various forms, and other diseases with which it has been mixed up: 

 he explains it, so as to lay a firm foundation for the work of later 

 times towards an explanation of its causes and origin. And Dr. 

 Danielssen had also his share in this later work; this may be said 

 without infringing on other people's claims. It was in the labora- 

 tory of the Lungegaard Hospital that the bacillus of leprosy was 

 first discovered, and he who discovered it will surely be the first 

 to acknowledge the important share the energetic cooperation of 

 the senior investigator had in the procluction of both this and other 

 works issuing from the same laboratory. Without Danielssen's 

 energetic interference, the honours of this important discovery, 

 now united to G. A. Hansen's name, would have been reaped by 

 a G-erman investigator. 



Besides .these large works, Danielssen, in the course of years, 

 has published a great number of minor treatises, on leprosy, as well 

 as on other skin diseases, in Norwegian and foreign medical 

 periodicals, and quite a long series of "Keports on the work of the 

 Lungegaard Hospital", containing extremely valuable information 

 as to the course and nature of leprosy. His useful contributions 

 on this subject have been constantly translated into the highest class 

 of foreign periodicals. We cannot however mention these writings 

 at greater length; but have to mention Danielssen's great work, 

 published two years ago, "The Vegetable parasitical Diseases of the 

 Skin'', the closing volume of the "Collection of investigations &c. u , 

 with excellent engravings, and linally his last work "Behandlung der 

 Lepra", which was not out at the time of his death. 



In this connection we must mention that Danielssens's influence 

 has procured for the Lungegaard Hospital a rich medical library, 

 which, besides being useful for producing the works issued from 

 the laboratory of the institution, has made it possible to publish 

 the "Medical Review", a periodical for reference, of great impor- 

 tance to the medical profession in Norway.
