[445] Jacquemart reports a striking case of impotentia coeundi, which he saw in an engineer who received an appointment in a State tobacco factory. After he had resigned his appointment, the patient fully recovered his sexual powers (cf. Loebisch, article “Tobacco,” in Eulenburg’s Real-Enzyklopädie, 1900, vol. xxiv., p. 19).

[448] In some cases it is said to have given rise to permanent impotence.

[452] The Englishman Thomas Parr, who attained the age of one hundred and fifty-two years, remarried at the age of a hundred and twenty years, and his wife is said “to have noticed no defects in him on account of his age” (cf. William Ebstein, “The Art of Prolonging Human Life,” p. 70 (Wiesbaden, 1891)).

[453] In the drug trade we find two brands, known respectively as “Yohimbin Spiegel” and “Yohimbin Riedel”; both preparations are of equal value. [In a letter to the translator under date January 8, 1908, Dr. Bloch writes that “Yohimbin Riedel” is preferable to “Yohimbin Spiegel.”]
