Otherobservers, Jendrassik and Klein, either deny its existence or regard it merely as alymphatic or an artificial product. Numerous fine lymphatics penetrate into theinterior of the organ, and many are distributed over its surface, but their mode oforigin is unknown. [They seem to be channels through which the tymph-CQr-puscles are conveyed away from the gland.]
