Back in the year 1844 when medical studies are not as extensive and accurate as it is today and back in the eras when masturbation was highly condemned as the culprit for almost every possible malady, flyers and pamphlets of "educational" awareness are not uncommon in the public areas of medieval times.
This particular extract from a 19th century FrenchBook With No Title is no different as it chronicles the deathly symptoms of excessive masturbation.
Cow Fistula, a scientific breakthrough allowing researchers a closer look inside the cattle's digestive system, literally.
Subjects of the study, the cattles, have been given a hole directly into the ruminant's rumen covered only with a seal called cannula. Agricultural scientists can reach within to examine the process, remove partially digested food than having to collect the cattle's feces, find food alternatives in the feedings and study the cow's internal digestion. With this induction of this aid, further lab investigations can be managed and other problems may be administered like stomach cancer.
There goes our Hole-y Cow!
