I read it once over and thought that it was a decent story but it did not grab my attention like some of his other stories. I seem to believe that it is a popular Lovecraft choice, but I would not place it at the top. I can tell you that right now, although it did contain quality structure so it was easy to read. I liked a few of the things that occurred in the story such as when West animated Dr Allan and also the part where their experiments turned into failures resulting in monsters. Basically West believed that life depended upon chemical automation. The need for fresh corpses might have gotten in the way of something better, but I did not feel any morbid reaction, only that the story was far fetched and perhaps because West did not have any reason to continue what he was doing except for some slight changes to the formula. I have recently read "The Island of Dr Moreau" by H.G. Wells. I think that Wells did a better job although his writing is lower quality. They told a similar story but Wells created a more plausible character and it was a stronger effort.
