The easiest way to find out where the diagrams are is to buy the right map. In this case it will be the "Adalbert Kermith's fourth map" which you can buy from the Lindenvale Blacksmith. Of course you can also look for the diagrams on your own.
During one of his numerous adventures, Geralt got his hands on a map covered with strange markings. He quickly deduced that they indicated the locations of hidden witcher caches and, intrigued by the chance of discovering long-lost crafting schematics, he set out to find them.
Adalbert Kermith's fourth map
The trail of symbols relating to the Cat School of witchers led me to four additional locations marked with the same sign. I was not surprised to see that the pictograms found in each do not differ from the one Professor Atimstein discovered in the caverns beneath Temple Isle.
As instructed, I have marked these locations on this map.
