THE OEGANS OF REPBODUCTION 107 



Dr. Steinach has recently summarized his work 

 in an article for a technical journal entitled Ver- 

 jungung durch experimentelle Neubelebung der 

 alternden Pubertatsdruse; which may be translated' 

 into "Rejuvenation through experimental revivify- 

 ing of the senescent puberty (interstitial) glands." 

 This article under the short title of Verjungung 

 has since been published in book form (by Springer, 

 of Berlin). 



Professor Steinach's work receives support from 

 that of Dr. Lichtenstern, a lecturer at the Univer- 

 sity of Vienna, who has successfully performed 21 

 transplantations and 36 operations in cases of 

 senility. Yet we must also observe that Professor 

 Kolber, another colleague of Dr. Steinach's, who 

 has made a careful histological study of the inter- 

 stitial cells with the view to elucidating their func- 

 tion, is not wholly in agreement with Steinach ; and 

 perhaps in the form of a word of warning, if only 

 to ward off too much optimism, it may well be asked 

 why the repairment of a part of the organism a 

 very important part, we admit that has become 

 very generally dilapidated, should rejuvenate the 

 entire bodily machine. It must be remembered that 

 not only the interstitial gland, but the other duct- 

 less glands, are affected with the onset of old age, 

 to say nothing of the rest of the organism.
