[February 5, 1891. his most important works was in connexion with his researches on the five senses of bees, which made a considerable stir at the time. Baron von Berlepsch, seeing their value, induced Schonfeld Fig. 1. Fig. 2. to write article 105 of his celebrated book. Berlepsch always considered this contribution as a most valuable addition to his book. Through the instrumentality of Schonfeld, Dr. "Wolff searched for and dis- covered the organ of smell of the bee, which re- sulted in his writing his now classical work on the subject. Many investi- gations were made on the tem- j>erature which bees require for their well-being, and many arti- cles were written on this subject which have led to a proper un- derstanding of the theory of wintering. One of the most important subjects with which Schon- f eld's name is connected is that of foul brood. With regard to his studies on this subject he had to fight hard battles against Fischer and Von Molitor-Miihlfeld, which ended in Schonfeld's favour, and it is to him that we owe our present knowledge of the real cause of this most terrible disease of bees. As Schonfeld's experiments have been so misrepre- sented, and statements have been attributed to him that he never made, we make no apology for giving an extract from the Bienenzeitung for 1874. Following the investigation of Dr. Preuss, who discovered minute bodies of an oval shape in foul-brood matter, which he termed ' micrococci,' and which he considered to be the cause of foul brood, Schonfeld proved these supposed micrococci (Fig. 1) to be neither more nor less than the spores of a ' bacillus' (Fig. 2), and he maintained that it was these bacilli, and not micrococci, that were the cause of the disease. On page 201 of the Bienenzei- tung for 1874 Pastor Schonfeld, giving a de-. scription of his observation on foul brood, says:— ' On the 24th of July, the smell from an exa
