You are bidding on one Handwritten, signed postcard of Comparative anatomists, zoologists and physiologists Moritz Schiff (1823-1896).
With interesting content, about that growth of hair.
Dated (according to Postmark) Geneve = Geneva, the 16th November 1878.
Directed an the physiologist Prof. Dr. Siegmund Mayer (1842-1910) in Prague.
He mentions his work “Investigations into the physiology of the nervous system with consideration of pathology” (Frankfurt aM 1855) and refers to a passage (on p. 166f.) about the growth of hair, which is as follows: "Furthermore, I saw that if I had resected the auricular nerves on one side of a rabbit and then shaved away the hair in the corresponding place on both ears, or cut it short with scissors, the hair on the paralyzed ear grew back much faster and thicker , than on the healthy side. It is best to use black-eared animals for this experiment."
Moritz Schiff was heavily criticized for his animal experiments, which is why he was even put on trial in Florence, which is why he fled to Geneva, Switzerland in 1876.
Transcription:"Dear colleague! The statement that after cutting the vascular nerves d. ear d. My research shows that hair grows stronger. e.g. Physiol. d. Nervous system Frankf. 1855 pg. 166.
Two years ago I examined this fact in more detail using a paper given to me by Prof. Thury procured arthetometers{?} and found that d. growth on d. Page d. the cut sympathetic nerve is not uniform. At first there is always rapid growth, then sometimes days come when d. Progress is very slow and irregularly distributed, individual days with very rapid growth. On d. On the healthy side, such irregularities are not noticed or noticed much less, and the hair remains shorter overall for the same {???}. I would be pleased if you would like to publish this comment from time to time, as my pen is too busy for other things. With kind regards. Greetings, you result. M. Ship.
At night they grow more on both sides than during the day."
With Prof. Thury probably means the Swiss botanist Jean-Marc-Antoine Thury (1822-1905), professor of botany at the Geneva Academy and co-founder of the Société genevoise d'instruments de physique (SIP) for the production of scientific instruments

About Moritz Schiff and Siegmund Mayer (source: wikipedia):
Josef Moritz Schiff (*28. January 1823 in Frankfurt am Main; † 6. October 1896 in Geneva) was a German comparative anatomist, zoologist and physiologist. He was the brother of the chemist Hugo Schiff and father of the Romanist and Hispanist Mario Schiff and the chemist Robert Schiff.
Life: Moritz Schiff, the son of a Jewish businessman, was originally intended to become a textile merchant, but instead began training at the Senckenberg Institute in Frankfurt in the late 1830s. From 1840 onwards he studied natural sciences and medicine in Heidelberg, Berlin and finally in Göttingen, where he also received his doctorate in 1844. He then went to Paris to study physiology with François Magendie and François Achille Longet (1811–1871) and botany and zoology (especially ornithology) in the Jardin des Plantes. After his return to Frankfurt he became director of the ornithological part of the Zoological Museum. In 1848 he served as a doctor in the revolutionary Baden troops.
From 1854 to 1863, Schiff was professor of comparative anatomy at the University of Bern. He had previously tried to complete his habilitation as a private lecturer in zoology in Göttingen, but was rejected because of “dangerous activities” in his youth. From 1863 to 1876 he was professor of physiology at the Istituto di Studii superiori in Florence, then at the University of Geneva. In 1892 he was elected a member of the German Academy of Natural Scientists Leopoldina. In 1895 he was accepted as a corresponding member of the Russian Academy of Sciences in Saint Petersburg.
Work: Moritz Schiff is considered one of the most important biological researchers of the 19th century. century. His first major contribution to medical science came in 1856 when he demonstrated that removal of the thyroid gland in dogs was fatal. He later found that the test animal's death could be prevented if it received a thyroid transplant or injections of thyroid extract. Schiff had sheep thyroid glands delivered to him by the local butcher, ground them and successfully used them to treat patients who had previously been operated on for goiter.
Schiff was the first to establish the influence of the cerebral cortex on blood circulation, to describe the effect of the vagus nerve on cardiac function and to establish that bile acids are subject to enterohepatic circulation.
For the first time in animal experiments, in his laboratory in Florence, as part of studies on death from chloroform, he performed direct cardiac massage on the heart exposed by thoracotomy (while the lungs were automatically ventilated) in animals brought to cardiac arrest with overdoses of chloroform. He thereby achieved a circulation artéficielle. In 1874, Schiff reported this to the Medical-Physical Society in Florence, and in the same year TG Hake published it without Schiff's authorization. Schiff only published his own publication 22 years later.
Schiff faced massive criticism for his animal experiments. He had to give up his experimental laboratory in Florence and flee to Switzerland when he was put on trial for his animal experiments. During this trial, he delivered an eloquent defense speech about the necessity and moral justification for animal testing. Schiff used anesthetics for his laboratory animals early on.

Siegmund Mayer (*27. December 1842 in Bechtheim near Worms; † 1. September 1910 in Amras near Innsbruck) was a German physiologist.
Life: Mayer studied in Heidelberg, Gießen and Tübingen, where he received his doctorate in 1865. He then worked with Hermann von Helmholtz in Heidelberg, Carl Friedrich Wilhelm Ludwig and Julius Friedrich Cohnheim in Leipzig and with Ernst Wilhelm von Brücke in Vienna.
In 1869 he received his habilitation in Vienna. In 1870 he became Ewald Hering's assistant in Prague. In 1872 he became an associate professor in Prague and in 1887 a full professor. From 1880 he headed the newly founded Institute for Histology.
Mayer left a significant amount of money to the medical faculty of the German University of Prague in his will. He is buried in Innsbruck. The monumental gravestone, a boulder in which the portrait of the deceased and a gravestone are embedded, is located in the Protestant section of the municipal cemetery.
